PLEASE READ FIRST
This post will have info on the chroot method. To find out info on running Ubuntu natively on the Adam, click this link for post #2 below. Enjoy
chroot Method:
chroot Ubuntu on Adam Beta1...
For now project files for chroot method will be located at this Google Code Project site. Files will be posted shortly, stay tuned.
DO NOT attempt this yet until specified as alpha or beta or otherwise stated as ready for testing!!
Liability:
I'm not responsible for what you do with your device, this is a guide or tutorial for general purposes only.
If you do not have a strong understanding of rooting and how to recover a device from scratch DO NOT attempt this until we are our of beta stages. Wait till you see RC status at least.
Verified working with bugs
Directions:
I'm not sure what file format is needed on the SD card, so make sure it has the stock file format from Android.
Make sure you are rooted using the methods listed here or Notion Ink Hacks Forum.
Download necessary files:
- Main scripts: Download from Google Code Project webpage. http://code.google.com/p/chroot-ubuntu-ni-adam-tablet/
- Ubuntu.img file: Download from MegaUpload. http://www.megaupload.com/?d=3ZQTCUUN
Create a folder on root of your Adam SD card called "ubuntu" and download the files from the Google Code Project site to this folder.
Unzip "ubuntu.img.zip" package and copy or move "ubuntu.img" file to the ubuntu folder you created above. Delete all the rest of the files. Do this to make sure you do not confuse the scripts I've put together for the Adam.
Plug Adam into your computer and make sure you have a connection to it.
Android SDK installed on a local computer with ADB functioning.
Make sure you do not have the SD card mounted on your computer. Also make sure USB Debugging is turned on, which I think you need for ADB.
Change the name of "bootubuntu[x].[x]" to just "bootubuntu"! DO NOT use the original "bootubuntu" file.
If you haven't already open a command prompt and type:
Code:
adb shell
Enter superuser mode:
Code:
su
Change directory to the "ubuntu" folder:
Code:
cd /sdcard/ubuntu
Run the setup script (You should only have to run this once or whenever new updates to the files are released):
Code:
sh ./ubuntu.sh
Once the script finished you should be good to go, type the following to run Ubuntu:
Code:
bootubuntu
If you see something like the following below, job well done!
Code:
[email protected]:/#
Troubleshooting:
If you get any errors, please FIRST, try rebooting Adam and start back at "adb shell" step 7 and try again.
More to come
If you get any errors, please post at what step number you got an error and post as much detailed info as you can about the error. Myself and others will do what we can to help.

More to come, holding this place for future use...
No problem for testing it ... but not before the end of next week
My Adam will be send on 31st of January
There is nothing to test yet. Not until more research is done and files gathered. Not to mention we still need full root and unlock first.
Do not attempt to run the files in that link.

For Rooting Adam it seems that it's done ?
And Don't worry i will not try to use fill that wasn't for Adam.
If you need help ... to search, test ... I will be part of ;o)
Thanks Gkar! Just be sure to follow this thread as any updates will appear here.
Also, root methods have been started but there are bugs. We need Adam users to help with that process first before helping here. Once that process works consistently I plan to get started on this.

Pfffff ... I've just seen on pre-order page that my date has been pulled to 14th feb 2011 and then i will have to wait to test !!
Ubuntu netbook edition
Btw, I am sure you have seen this, but Ubuntu does have a Netbook Edition. It brings all the advantages of Ubuntu to a netbook – using Unity, an innovative user interface super-optimised for smaller screens and also convenient for touch screens.
So, this may be the best version to port to Adam if we can get it going. I unfortunately have no development knowledge to know if it is possible.
Mmmmmh .... i'm using Netbook edition on EEE 901 for my kids but unity isn't mature.
I prefer old version of Netbook edition (10.04 LTS) ... and that's the version used to create Ubuntu Distro for HD2.
Maybe we can ask them for some help.
I'm interested on this too. For the record, I'm keen to get an Adam and wipe Eden, replacing it with Ubuntu. I think Ubuntu 11.04 will be an awesome distro to run on a tablet, and currently Notion Ink's Adam is the only one being made that meets the stats I'd like to see.
The current hacks that exist to get Ubuntu running on the Nexus One (have done that) require running a modified server version from the sdcard, the using VNC to run a virtual session. Has it's plusses (running within Android, for instance), but I'm keen to see Ubuntu running natively. Android isn't mature enough to be a main system yet, whilst Ubuntu is. Cheers.
hope a port is cooming soon
Yeah, I'm very eager to try this too
Maybe a dual boot with Android ?
Looking forward to it
Thanks for your patience everyone. I've been swamped. This weekend I plan to hunt down some files, look at the scripts, and hopefully we can start trying this shortly!
This is one of the main reasons I have been waiting for the Adam for so long. Hopefully we can dual boot Ubuntu as that is what I would prefer, but if not, oh well. I want to have a tablet that acts more like a computer then a glorified smartphone without phone capabilities... Can't wait to see the development of this!

Dual booting is always preferred yes, but that is not what my method will do. This method will be a bootloader running on top of Android. For many reasons this will be easiest for now.
I'm very excited about this, can't wait to have my Adam and following the developent of ubuntu.
I really think, on another hand, that Android and Ubuntu are majors players in the open-source OS and should therefore communicate better.
I want Adam to be the best friend of my Ubuntu desktop. There are so many possible ways to make these OS interact, at least the way iOS talk to Mac OS X.
i can't wait for my Adam to be here to write apps in this direction!
I love that idea as well. Would be cool if there was a way to integrate Ubuntu netbook edition and Android.
Sent from my PC36100 using XDA App
Ubuntu netbook edition and the desktop version are now the same thing with the upcoming release. Actually, the whole UI of Ubuntu is getting a major overhaul to be touch centric. Currently, my nexus one running cyanogenmod DOES talk to my Ubuntu netbook. And server. Very well in fact. Tomdroid for notes reads all off my desktop tomboy notes, and Funambol, with syncevolution syncs my calendar and address book.
Have just ordered an Adam with a friend, and plan to hack it extensively until Ubuntu is running in full, natively, as it's primary operating system. Android is useful, but doesn't have the functionality of Ubuntu. Would be useful having android as a secondary system, or within Ubuntu, but I won't hold my breathe.
I agree though, the first step seems to be getting Ubuntu running within android. I'm starting to research how the bootloader needs to be hacked to recognise a usb or dvd drive to boot from, and how it would "see" ubuntu installed on one of the internal drives. Will post back with more info soon, even though this is further down the track.

I ordered my Adam Once I saw it figure in XDA forum. My experience with XDA especially with SGS phone has been immensely satisfying. The way Things are going I am sure Adam will be an object of envy before long.
From a development and user standpoint I am of course interested acquiring root for the android side of things but my main interest and focus on gaining the ability to modify and enhance the webtop image that provides the "full feature" capability for Firefox. So in a sense there is a goal for Double Root on Atrix. Rooting first the android side and then rooting the webtop Linux instance.
I am guessing from the looks of it that webtop is based on Ubuntu Light. It is also likely run in a VM otherwise the phone instance of android (Dalvik) and the Webtop could not run simultaneously. Given that the platform is probably something to the effect of:
Linux File System -----> Dalvik VM ------> Android Runtime
Linux File System -----> Some other VM? -------> Ubuntu Light
I am running under some assumptions (not having an Atrix till next week ):
* The "Some other VM" is not Dalvik since I don't think as an App VM.
So some of the questions I seek to answer right away are:
What VM is running (presumed) Ubuntu light
Does that VM have security around the disk image (singed)
Is the (Webtop disk image) encrypted/signed
What is needed to get root access on the Webtop side.
The best way to get root on the Webtop side is to go after the file system. I am guessing that will be signed but it MUST be writable at some level to save state.
Just a bunch of musings. I am looking forward to getting my atrix so I can start answering some questions.
I think getting root to one or the other will make it VERY easy to root ther other.
I for one hope it is ubuntu lite, or something debian based. Hopefully make it really easy to port over a full distro.
being able to boot into a full linux distro would be the cats meow!
i have full expectations of being able to do this within a month or two ;-)
Do you guys think it would be possible in the coming weeks/months to be able to boot into a full linux distro on the Atrix itself - without the laptop dock?? that would be ultimate awesomeness right there!

It's also possible that they have a Linux variant running on bare-metal, without a VM. I have seen some architectures in the embedded world that allow each CPU core to work together as a typical dual-core system, OR to boot a different OS kernel on each core.
The latter case would be the most interesting in terms of getting the most out of Linux on the Atrix, assuming the second OS can be rooted. This could (speaking with almost no knowledge of Android itself), also be another angle of attack/defeat though if that means the webtop linux kernel also needs to be signed...
Then again, a VM does make more sense in terms of the near-instant boot time of the WebTop mode.
I can't wait to see the "double root... oh my god... what does it mean???" Youtube video come out in a few weeks =)
If I can get a command prompt and root access on the Webtop instance I will sound just like the Double rainbow guy.
Things I believe to be true right now.
WebtopSession app initiates then session when you plug in HDMI. This is no different than any other peripheral launch.
WebtopSession app (speculating based on other posts) checks you connection type and provisioning. If you don't have a tethering plan it doesn't allow you ton continue. If you are on wifi it allows you to continue.
If you start off on WiFi and then change network state to mobile radio (and no tethering plan) will it discontinue the session?
The WebtopSession App doesn't look like it does anything other than manage the initiation of the Linux (Webtop) session.
There is nothing in the dumps that looks like it could remotely be a disk file which makes me think that there is a partition that is different that the normal android partitions. I would love to see a partition map of a rooted phone.

im also wondering this!
edit: Erm. Whoops. A little bit of research and it turns out Motorola has left the code in for when they test the OS in "goldfish-qemu", an Android emulator. Sorry ><
It's got to be QEMU. In the retail firmware dump in /etc/init.goldfish.sh:
Code:
# call 'qemu-props' to set system properties from the emulator.
#
/system/bin/qemu-props
So what I'm thinking after parsing the information I've got...
... WEBTOP is simply a QEMU (ARM version?) instance running off of some unknown image/partition on flash that outputs to HDMI with some hackery to support local media [mounted in the host OS, Android] and local control and USB keyboard/mouse input, along with special extensions to allow for use of the Android/host OS instance within the VM.

Oh maaan. Double root all the way What does it mean???
In all seriousness, the Atrix is certainly the most interesting phone from a developers standpoint, but I'm sitting and watching for a bit as I want to see how much of a problem the signed bootloader becomes first.
So does the Signed Bootloader rule out the Double root ? or changes to the Webtop APP/Module ?

It depends. Signed bootloader refers to the fact that the phone boots only if certain partitions match the Moto signatures.
The question is, where does the Webtop mode boot from, and is any part of *that* boot process signed?
I don't know why you guys think it has to be running in a VM. It's more likely they have just install Xorg and Firefox on Android and run them, with X displaying on the HDMI.
Exactly the same as the ubuntu-on-android hacks, but instead of using VNC to view X, you just display it on HDMI.
The phone view is an X11 app which communicates with the Android system server to mirror the display.
I seriously doubt they are using QEMU or anything like that.
Bah! Edited post since my last one was way off.
Did some looking and it looks like qemu in this instance is related to running some proc emulator for android development sdk support.
There this is a bunch of stuff out if you google: android goldfish
Its related to ARM targets for the sdk and in this instance probably not webtop.
I'd still really like to see the output of:
adb shell
cat /proc/mtd

Agree. But from the DG's / dump could not find more interesting info except the WebtopSession.apk. I guess webtop stuff live in another patition which is actived when webtop session starting.
Could anyone who has a rooted Atrix dump the phone while webtop on?

I don't have the webtop device. What about while the phone is plugged into the TV? If it'd help any just give me the steps and I'll do it.
Yes if you plug your phone into the tv it will be able to access webtop.
I am pleased to announce that I've patched the Atrix webtop files, allowing us to run webtop over HDMI on HKTW, AT&T 4.5.91 and ORFR 4.5.2A based system images (yes this will work on custom ROMs too), without the requirements of an official dock!
The goal is to enable the Webtop function over HDMI on any display, not just official Motorola Docks. There seem to be more HDMI display options that are disabled, for example: Clock Widget, Gallery, Music, Home. Sadly, none of these options actually do anything on the big screen, they just display the interface on the phone
However, Webtop works great! Just use the instructions below to replace the original DockService and PortalApp apk's.
Included are two versions of the DockService in the zip attached to this thread, one will enable only the additional Webtop mode for HDMI. The second one will be a "dev" version that enables every option, for those of you that are curious and/or want to try to get some of them to work over HDMI! Only one version of PortalApp is included, which is required for webtop to work, with both versions of the DockService.
One particularly interesting option that many of you are interested in is included in the dev build too: Mirror phone on display . Sadly, as stated above, it does not work (yet?). Will you get it to work?
Requirements:
Have one of the supported build and functional webtop flashed
Be rooted
Be able to work with adb
First, unpack the attached zip-file.
Go into the correct directory for your version.
Now run (in a terminal)
Code:
adb push DockService.apk /sdcard/
adb push PortalApp.apk /sdcard/
adb shell
# you are now in the phone shell
su
mount -o rw,remount /dev/block/mmcblk0p12 /system
mv /system/app/DockService.apk /system/app/DockService.apk.bak
mv /system/app/PortalApp.apk /system/app/PortalApp.apk.bak
mv /system/app/DockService.odex /system/app/DockService.odex.bak
mv /system/app/PortalApp.odex /system/app/PortalApp.odex.bak
rm /data/dalvik-cache/*DockService* /data/dalvik-cache/*PortalApp*
cd /system/app
cp /sdcard/DockService.apk ./
cp /sdcard/PortalApp.apk ./
chown 0:0 ./DockService.apk
chown 0:0 ./PortalApp.apk
chmod 644 ./DockService.apk
chmod 644 ./PortalApp.apk
reboot
NOTE: if these instructions dazzle you, try Ronaldo's CWM package (for AT&T only!): http://forum.xda-developers.com/showpost.php?p=15871616&postcount=53
NOTE2: ignore errors concerning odex files if you are deodexed.
NOTE3: If you have issues with the Touchscreen Input not working, try a reboot first. If the problem doesn't go away: fastboot flash a (stock) webtop image for your base ROM. It is currently unclear what causes this problem, but my guess is a bad flash of the webtop partition, possibly CWM related. Reboot/reflash has solved the problem for a few people encountering this issue.
Thanks to Gizmo, eval & romracer!
More information on dev version
Some extra information on the different modes that are available (but currently non-functional):
Clock: Transform your phone screen into a big clock with perks. See the time from afar, set alarms, play music, view photos and get live weather information. This mode was designed for your bedside but is useful in the kitchen and as a desk clock too.
WidgetDock: Get access to the same Android widgets, apps and shortcuts as on your phone home screen. Arrange them and change the wallpaper to your liking. All of which will be saved and applied the next time your dock your phone.
Mirror: Access and display all of the phone applications on a larger display
Other: Displays non-smart mode dock apps
Gallery: View photos and videos
Music: Access, listen, and share music
There is also mention of an "easport" option, with the following description: "Entertainment detailed description goes here. To be added later."
Although not working currently, they give a good insight in what is to come
IMO, one of the best features of the Atrix right here. You're the man!
Great, I was looking forward to this. Thanks again.

Everything works fine
Holy **** ! That is all.
So, frist, thanx for this excelent work! Now my webtop works.
I just have one problem, my mousepad on lapdock doesnt work!
works great! thanks!
Awesome work! I only used my atrix for a few minutes before flashing 2.3.4 so I have no idea how well this worked before, but I'm pleased. All I know is when I plug in the HDMI, it restarts into the webtop mode and it works well from there. The entertainment center app crashes but that isn't as a result of this, it definitely did that when I tried to run it before.
mouse not working
loads fine but no mouse control for me either..
Same for me. The webtop loads up fine, but no mouse control on the touchpad.

if by touchpad you mean using the screen of the phone as a touchpad, it's working fine. I don't have a lapdock to test, but I could walk over to the AT&T store in the AM to check it out.
Edit: if that is the case, and something is working on my Atrix but not on many others, I assure you it was just a lucky accident. I may be a systems engineer by date but by night I'm little more than an Android n00b. I'll gladly poke around on my device to collect info that might help others get their webtops sorted.
I successfully flashed the webtop and the touchpad is working fine. But I did notice at times, GUI became unresponsive to the touchpad (touchscreen). It it not perfect, but it works
See now this almost makes me wish I still had my Atrix...
I would love to tinker around with these APKs some more. Especially with the new options cropping up.
But, as it is I am doing it all blind... doing DEV for a phone you don't have is tricky business.
Awesome!! Worked perfect!
Installed using ADB via OP commands. Never flashed the CG61.img or the Update's for HKTW 2.3.4 - Roll-up of Fixes and Mods (Navalynt's Mod) that included the Webtop Fix and I am having absolutely NO problems using the screen as the mouse pad.
Make sure you followed all commands and set the permissions correctly with the chmod command.
No problems at all here, but I did flash the non-dev apk.... if you flashed the dev apk then that may be where the mouse pad issue is, I can not confirm.
I've spent some (much) time this week with trying to get ubuntu running on the optimus 2x. I have succeeded to boot and get the wifi, X11 and the touch screen sort-of working.
The ramdisk is completely replaced with a busybox executable, some symlinks to it and a shell script that mounts the necessary stuff (/dev/block/mmcblk1p2 as ext3), changes root directory and calls /sbin/init.
USING THE FOLLOWING WILL VOID ANY WARRANTY YOU MIGHT HAVE LEFT AND MIGHT ALSO BRICK YOUR PHONE!
Seriously, don't do this if you don't wish to risk the data on your phone.
I will be providing some demo images for people who don't have a build environment up and running. These images will not work particularly well, don't get your hopes up .
If you want to have a big linux installation (more than 3 GB) you can flash the images to the second partition on your external sd (obviously you have to create this yourself first). You can use the following boot image (which assumes that linux is on /dev/block/mmcblk1p2 with ext3:
https://ha.xxor.net/o2x/boot-20110813.img
I have also targzipped the modifications to the file system that were required to get stuff going here:
https://ha.xxor.net/o2x/o2x-20110813.tar.gz
This should be extracted directly to the root file system.
The kernel source code is up at https://github.com/ergoen/LG-Optimus-2x-linux-kernel
Things that have been done to get this to "work":
1. Boot partition
Apart from grabbing the busybox stuff from some nexus one boot image (I'm sorry whoever fixed it, I don't remember where I got it from ) the boot command line had to be modified a bit, changing stuff from the default usually ends up in a phone that won't boot, but I discovered that it's possible to append new arguments to the default ones. So the following have been appended:
console=tty0 root=/dev/mmcblk1p2 init=/sbin/init
The console=tty0 makes sure that you see stuff on the screen while ubuntu get's running. The last two are not necessary to boot, but ubuntu seem to like (need?) them (or at least the init=/sbin/init), since otherwise you never get to the login prompt on the screen.
2. The Ubuntu installation
To make it possible to communicate with the phone at all adbd was put into the /sbin/ folder and a symlink was created /system/ -> /. Also the "/sbin/adbd recovery &" command was added to rc.local to make it autostart.
2.1. Modules and wifi
We need the /lib/modules/2.6.32.9 directory. Most files inside that were generated using the "depmod" command, the exception is wireless.ko which was taken from android, the firmware and nvram files needed for the wifi chip to work were placed in the /lib/firmware/wl/ folder. To make the wifi module autoload with the proper firmware "wireless" was added to /etc/modules and the file /etc/modprobe.d/wireless.conf was created with the contents describing the location of the firmware and nvram.
To make the wifi autoconnect on boot the /etc/network/interfaces file was modified with the following contents:
auto wlan0
iface wlan0 inet dhcp
wpa-driver wext
wpa-conf /etc/wpa_supplicant.conf
(To make the wifi autoconnect to your wireless you need to run the command "wpa_passphrase networkname networkpassword > /etc/wpa_supplicant.conf using adb or chroot)
2.2. X11
Getting X up by running xinit produces a simple black screen on the phone. At first I thought the problem was that the refresh rate was set to 106 Hz, indeed changing it with xrandr and pushing a new mode got me a visible xterm on Kubuntu 11.04:
https://ha.xxor.net/o2x/xterm.jpg.
On Ubuntu 10.10 it even gave me a nice colored gdm screen:
https://ha.xxor.net/o2x/gdm.jpg
But the image I got there was static and wasn't being updated. Turns out the reason the screen was black earlier with the 106 Hz rate and the reason why the screen is now just showing an image is that the framebuffer device doesn't update the screen like it should..
By modifying the kernel source to redraw the screen every 50 ms (~20 Hz) it's possible to get a scren that works. This is an ugly hack in the tegra-fb driver though, so I'm open for suggestions on how to solve it in a better way!
2.3. Touchscreen
By default the only thing the touchscreen does is force the mouse up in the left corner, I think this is due to some multitouch thing. Some more kernel hacking (basically half-disabling multitouch) makes the touchscreen work.

3. Misc
(K)Ubuntu 11.04 uses a new version of libc which crashes with the current nvidia kernel (2.6.32.9) on this hardware (http://developer.nvidia.com/tegra/forum/errata-657451-tls-bit-20-cp15-c13-3), so I'm going back to Ubuntu 10.10 until someone ports a newer kernel to the Optimus 2x or this problem can be solved in another way.
edit 1: Ubuntu 10.10 with much more working X11 noted in section 2.2.1.
edit 2: X11 working even more, touchscreen works aswell!
edit 3: Landscape mode works with both X11 and the touchscreen now, getting ready for alpha 1!
Current status:
Working:
- adb (best way of controlling device currently)
- X11 (only framebuffer with hardcoded refresh rate of ~20Hz)
- landscape mode fixed! =D
- touchscreen (probably only single touch)
- wifi (only when running things from console, ubuntus network manager does not recognize it)
Not working:
- Basically everything else
Alpha 1:
EDIT: Seems that multiupload has screwed up and this link was going to some crap, anyway this is not relevant anymore
Username 'ubuntu', password 'ubuntuxda'. Don't use this if you don't know how to restore the boot partition! (Or else you won't be able to boot back into android!)
Experiments:
Tried disabling the CONFIG_TEGRA_ERRATA_657451 switch in the kernel to make newer linux versions boot. This might be a bad idea in the long run, but this far things are working better than with the switch enabled..
I tried Ubuntu via chroot method posted in other thread, but I'm a noob.. Can you please explain what is different about your ubuntu?? Does it boot without Android and doesn't need VNC stuff?
Yes, it boots instead of android when turning on the phone, but it doesn't work completely, so I mostly put it up here so that people could help test and fix/hack things.
You rock! Unfortunately I'm no dev, so can't help but hopefully others will, so we'll get a fully working linux on our phone, and maybe later even meego. Is there btw drivers for the gpu? Because hdmi, with usb host ofc, would be really useful!
Anyway, good job, really!
This looks great ergoen! I'm no dev either but I can't wait until it's available to everyone, I would love to have Ubuntu running on my O2x.
Best of luck!
gpu drivers are closed source, and the ones released by nvidia require a newer kernel (2.6.38), so thats not really possible yet.
Newer kernel will be necessary anyway though, since the crashes I'm getting seems to be due to a bug in tegra which gets worked around in 2.6.36. I'm not skilled enough to perform that port though. I will of course give it a try, but most likely I'll go for some older version of ubuntu and/or perhaps meego instead.
Håller med tidigare poster. Would be awesome with native Ubuntu and Meego on the phone... keep up the good work, can't wait to follow this development.

What would happen if you changed this to 72Hz instead? I saw that info when I was browsing System Information in some app. Im not a dev At. All. But tell me what you think it's probably a stupid question

I can give it a try later, not that it would make any difference .

I've spent some (much) time this week with trying to get ubuntu running on the optimus 2x. I have succeeded to boot and get the wifi working, also X sort-of works (software fb). I have only slightly modified the kernel (built with CONFIG_SIGNALFD=y so that Meego wont complain in a related attempt to get that os booting). The ramdisk is completely replaced with a busybox executable, some symlinks to it and a shell script that mounts the necessary stuff (/dev/block/mmcblk1p2 as ext3), changes root directory and calls /sbin/init.
USING THE FOLLOWING WILL VOID ANY WARRANTY YOU MIGHT HAVE LEFT AND MIGHT ALSO BRICK YOUR PHONE!
Seriously, don't do this if you don't wish to risk the data on your phone.
I will not provide a complete root file system for two reasons:
1. It's pretty easy to make yourself, grab the omap3 kubuntu mobile image from the kubuntu site, or use rootstock from an ubuntu installation to build one yourself.
2. My upload sucks, and putting several hundred MB onto the interwebz would hurt me.
However, I have placed an image of my boot partition here (assumes you've got ubuntu on the second partition of the external memory card formatted with ext3):
https://ha.xxor.net/o2x/boot.img
I have also targzipeed the modifications to the file system that were required to get stuff going here:
https://ha.xxor.net/o2x/o2x.tar.gz
This should be extracted directly to the root file system you aquired earlier.
Things that have been done to get this to "work":
1. Boot partition
Apart from grabbing the busybox stuff from some nexus one boot image (I'm sorry whoever fixed it, I don't remember where I got it from ) the boot command line had to be modified a bit, changing stuff from the default usually ends up in a phone that won't boot, but I discovered that it's possible to append new arguments to the default ones. So the following have been appended:
console=tty0 root=/dev/mmcblk1p2 init=/sbin/init
The console=tty0 makes sure that you see stuff on the screen while ubuntu get's running. The last two are not necessary to boot, but ubuntu seem to like (need?) them (or at least the init=/sbin/init), since otherwise you never get to the login prompt on the screen.
2. The Ubuntu installation
To make it possible to communicate with the phone at all adbd was put into the /sbin/ folder and a symlink was created /system/ -> /. Also the "/sbin/adbdb recovery &" command was added to rc.local to make it autostart.
2.1. Modules and wifi
We need the /lib/modules/2.6.32.9 directory. Most files inside that were generated using the "depmod" command, the exception is wireless.ko which was taken from android, the firmware and nvram files needed for the wifi chip to work were placed in the /lib/firmware/wl/ folder. To make the wifi module autoload with the proper firmware "wireless" was added to /etc/modules and the file /etc/modprobe.d/wireless.conf was created with the contents describing the location of the firmware and nvram.
To make the wifi autoconnect on boot the /etc/network/interfaces file was modified with the following contents:
auto wlan0
iface wlan0 inet dhcp
wpa-driver wext
wpa-conf /etc/wpa_supplicant.conf
(To make the wifi autoconnect to your wireless you need to run the command "wpa_passphrase networkname networkpassword > /etc/wpa_supplicant.conf using adb or chroot)
2.2. X11
Getting X up by running xinit produces a simple black screen on the phone. After some troubleshooting and voodoo magic I realized that it tried to run the screen at [email protected], which is hmm, wrong . So setting up a script at /etc/xprofile, which makes sure the refresh rate is 60Hz, and running it after xinit gets you a xterm!!!
https://ha.xxor.net/o2x/xterm.jpg
Telling /etc/X11/xinit/xinitrc to run it makes sure that it gets set up properly by the startx script, unfortunately startx doesn't go through for me on kubuntu because of some weird error caused by a hardware problem in tegra: (http://developer.nvidia.com/tegra/forum/errata-657451-tls-bit-20-cp15-c13-3).
Unfortunately this (probably) means that either we'll have to stay with old versions of libc or get a newer kernel (2.6.36 contains fix). Old libc seems backwards, but porting a new kernel requires a bit more skill than I possess.
2.2.1. Ubuntu 10.10
Grabbed the image ubuntu-netbook-10.10-preinstalled-netbook-armel+omap.img.gz from http://cdimage.ubuntu.com/ubuntu-netbook/ports/releases/maverick/release/ . After first unpacking the tgz, then unpacking the raw disk image to partition images (with 7zip on windows) and then flashing the 1.img file to the second partition on my sdcard I managed to run a much more bug free ubuntu than before.
Ubuntu 10.10 (Maverick) uses an older version of som libraries that don't crash with the old o2x kernel.
This has lead to the following:
https://ha.xxor.net/o2x/gdm.jpg
Obviously touch screen isn't working properly (pressing it puts the pointer into the upper left corner :S) so can't get further than this currently.
3. Misc
avahi-daemon and cups seems to be crashing all the time and restarting, so removing them (apt-get purge if ubuntu/kubuntu) will make the boot much cleaner. Also I get lots of alignment trap kind of errors that shouldn't be there for different kinds of services, (due to tegra bug mentioned earlier).

Most computer screens usually support atleast 72hz also, it's just that it only works with d-sub, and sometimes only at a lower resolution.. It's possible to make special drivers to some screens to enable higher refresh rate through dvi also.
Anyway, it's good the screen on the phone refreshes at 72hz instead of 60 for android, but in linux I really don't see the benefit.. Doesn't hurt to have though. Btw, if we would stay on this kernel, can we use the drivers from android then? Shouldn't gpu also work? Or are the drivers limited and don't allow xorg for example? Sorry if it's stupid question, don't have that much knowledge how android works yet.
Update: X11 and touchscreen work on Ubuntu 10.10 Maverick with new kernel (just a few hacks )!
manasgirdhar: sure! Lot's of things to do new kernel is needed for anything newer than ubuntu 10.10, and even here things like sound etc (cpu scaling maybe too) don't work.
kruppin: actually i removed the xorg.conf now, the phone thinks its running at 106 Hz and it works. Unfortunately in practice it goes at more like 20 Hz because of the hack I made to enable the fbdev output in the kernel. Android doesn't use X11, so those drivers wont be of any use. (I will post the kernel modifications to github soon)
edit: kernel source up on https://github.com/ergoen/LG-Optimus-2x-linux-kernel
A List of Things working at 2nd Post would be nice.
So anybody could fast see Updates,...
Edit:
Have you tried some "cleaner" Linux like Debian?
Alpha 1 is up in the second post for anyone who wants to test it (don't ^^).
I have not tried debian no, I thought ubuntu would be the easiest to google errors and bugs for .
You are great! i was hopin' for this since I have mine. You should try to make usb(otg) work to get some devices going i will try to test it soon
That's amazing We have to test USB OTG function. If it works by default, I'll try this right now
It is possible to make a dual-boot: ubuntu and android?
I don't think usb otg works since I am basically using the android version of the kernel, I also won't be able to try since I don't have a cable... (will buy one sooner or later).
Dual boot probably works if you flash the boot.img onto the recovery partition instead of the boot partition (/dev/block/mmcblk0p7 instead of /dev/block/mmcblk0p5). I have not tried this though. That way regular booting would give android and booting while holding volume down would give ubuntu, only problem with this is that cwm will be gone and the only way to fix broken things would be to flash with nvflash.
well it is not a major deal if have cifs avail needs kernel support as well. Benee mentioned (might) some otg support, mayb u could ask.
also, you might give E17 a try, it is butter-fast, and has a touch module for keyboard (letter zooming.!..) LINK
this can be compiled on a lot of hw, and gives good response with fbdev non-accel drivers also.
and most linux apps work on it fine. ofc until we have 2d/3d accel and might try compiz/fusion as well
LINK
Great job ergoen!
I've worked on exactly the same some weeks ago but i never accomplished it. because i stuck creating a working ramdisk. Which toolchain do you use?

Since we got a x86 cpu i want to use ubuntu on it, as im from germany i still dont have my I but has anybody tried linux on android?
Adam Outler mentioned something that this would not work...
Btw can somebody tell me what the kernel version is..?

Kernel version is 3.0.8.
If you can install linux distros on the backend of rooted ARM devices it should make sense we could do the same....maybe
Ubuntu on a RAZR I ? Linux x86 apps + windows apps with wine without even recompile? I think this devece needs some love. It can be the next HTC HD2 for shure.
I dont understand the htc comparison
But i have your ideas about no need to recompile and wine in mind too...
But i understand adam because linux for android is compiled for arm achitecture so a usual desktop image would make more sense...
Why is the kernel version so low?!

What we need to do
I have a friend with this device, after rooting he reports there is no chroot command from terminal. If so we must:
Compile busybox (with more extensions) for x86 and install it alongside root (or after root)
Make a mountable image from an ubuntu clean install and mount it (probably also needs busybox)
chroot into this mounted image
run a vnc X server on a framebuffer
vnc from android
This is how it is done on other android devices, will attempt to compile and try these instructions out this weekend when I meet him but booting native ubuntu is a much better idea (even better if we can make it receive calls ).
And for what Windows on 4,3 inches display? It dont have hdmi.

Go look up the HTC HD2. It can run Windows Phone 7 and Android dual-booted (with Linux from SDCard), and was originally the last, albeit most powerful, Windows Mobile 6 phone ever made.
Even though it is four years old, there is a massive and vibrant dev community behind it, making it reach the front page of XDA forums.
However, even the venerable HD2 is getting old, with 1GHz processor and half a gig of RAM that was top-of-the-line years ago, and people have looked in vain for some kind of successor. Hopefully, the Razr I, with an unlockable bootloader and Intel processor, will be the one. But that remains for us to do.

So I tried this out and there is a chroot-compatible busybox after rooting ("busybox chroot" needs to be called as opposed to "chroot" as there is no properly made link), so anyone with this phone can try (using a PC) install Ubuntu without the grub bootloader using manual partitioning on a single ext3 (I am not sure if ICS supports ext4) partition on a microsd, put into your phone, use a root terminal, mount it, mount the adequate dev, dev/pts, proc and sys partitions and chroot right in. You then might want to install a VNC server in Ubuntu to be able to create a VNC X session in a framebuffer and a VNC client on the android side to VNC into localhost (127.0.0.1), but that should work, I didn't have time to try it this weekend If someone gets stuck post and let us see what happens I cannot wait to see if wine can run desktop Spotify with sound, excited a little hehe.
EDIT: So to make this more understandable you must:
Install Ubuntu (using your computer) to a MicroSD, specifying partitions manually and choosing only a single ext3. Right before clicking install there is a button with something along the lines of "Advanced options", disable the install the bootloader (grub) option.
Insert the MicroSD into the phone and open a root terminal
I don't use Android, maybe it automounts in /media/sdcard or /sdcard, if not you will have to find the device and partition name (probably /dev/mmcblk0p1 or /dev/sdb1) and issue "mount /dev/DEVICEPARTITION /media/sdcard"
mount -t proc proc /media/sdcard/proc
mount -o bind /dev/ /media/sdcard/dev/
mount -t devpts devpts /media/sdcard/dev/pts
busybox chroot /media/sdcard /bin/bash
Now a shell from Ubuntu should open. apt-get update && apt-get install vncserver (maybe the DNS settings must be set in /etc/resolv.conf, not yet sure)
vncserver (or start vncserver, something along those lines)
Now from Android install a VNC viewer and vnc into 127.0.0.1 (or localhost)
That should do it, again if you get stuck post here
i had htc hd2, the most amazing phone in the world. I wanna buy the rarz i for the x86 processor in it. But cpu power without community and developers is nothing :|
Sorry for my bad english.
Yesterday we tried something:
We used dd to put an arch linux image on a micro sd card...
Though my laptop wasnt even able to boot from any sd card, this should work on our phone...
but how to make it boot from the sd card? xD
btw you might have noticed, this will make only linux boot, not android, we dont chroot, may somebody build a simple ubuntu img for complete linux installer?
//Robert
so right now i am trying to chroot into an img file, mounting it and then chrooting it but all i get is:
chroot: can't execute '/system/bin/sh': No such file or directory
whats wrong?

Hey,
great work. :good:
Good to see there are people with the same ideas. I´ve searched a lot for this thread.
I will also try to get this device for the same reasons when it´s cheaper. Has anybody tried to get Plasma Active or Tizen to run?
I think Active should now be possible through kubuntu Active?

Hi all
At first you can try a application from play store called Linux installer
https://play.google.com/store/apps/details?id=com.zpwebsites.linuxonandroid
Otherwise you can wait some weeks for an nexus 7 Ubuntu port witch looks really interesting.

thanks for your post on preparing an arch image (I don't have permision to post in devel forum, maybe because I'm a newbie ), It worked well for me although I had to adjust some things such as path and pts mount
I now have a gcc toolchain and a latex distrib on my phone I had never used arch, found it very good
I've also tried some window managers ... the one I find best for the moment is enlightenment in the touchscreen mode, awesome works great as well.
I would also suggest to use Hacker's keyboard instead of stock android, it is a complete keyboard, very usefull when dealing with terminals ... as for VNC viewer, one should recompile android-vnc-viewer with the patches given in Issues 238 and 239 (can't post links either), it's a lot better
I've had a lot of fun, thanks
First, Complete Linux Installer doesnt work because its images are compiled for arm not x86 (i tried )
Secondly, I did a tutorial here http://forum.xda-developers.com/showthread.php?t=1966984
the nexus 7 stuff is interesting and we consider making flashable fastboot for the razr i since we dont have cwm or such you know
i am talking to jordan keyes who recently owned a nexus 7 who probably will try out the ubu stuff and i might get some system info
but i would really prefer a dual boot, capable of booting from sd...
