[Q] Can I set HDMI output for a loop Ubuntu system? - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Hi, I've installed Ubuntu in a loop system, and can login in Graphics Mode with an VNC client on my own Android or in other VNC client on my LAN. I've bought the HDMI output adapter and now i want to redirect the Graphics mode of the looped system to the HDMI. Like "Ubuntu for Android" but in my Note. Of course i will haven't the integration of "Ubuntu for Android" but i have some free time to investigate.
Obviusly i can see the VNC sesion throught the HDMI, but what i really want is not need the VNC clients. It's possible?
(sorry for my poor english)

Nope, sorry.
In order to use HDMI directly Ubuntu would need direct access to the hardware and the hardware is obviously already in use by Android. Besides most Android - implementations to do not support outputting different image through HDMI than what it shows on the main screen.
In theory it might be possible to drive HDMI separately from the Android side with a modified VNC-application, but that requires some coding skills.

I wonder if it is posible to por mythrontend to g1 ?
I don't think it'd be a port, so much as re-writing from scratch.
Yes it's possible, but why would you?

Because its cool.
I'm not sure if you understand the architecture of mythtv...
There is the mythtv-backend (server) -- this component is the server you have plugged in to your cable or satellite box in your basement.
Then there is the mythtv-frontend (client) -- this component runs on as many other devices as you want. It can access the tv tuner and dvr functionality (among other things) provided by the mythtv-backend.
So what you have with it is a DVR client/server system. That means remote access for multiple clients to your TV stuff.
The idea here is to be able to make the 'droid phone into a mythtv client and access your home tv recordings and even live tv from *anywhere*. This is a *really really cool* idea.

Wirelessly Mirror Android on Projector?

Does anyone know if it's possible to basically "stream" the screen to a projector? I'm thinking of an app that would have a server running on the desktop PC, where the Nook would wirelessly connect to that PC and display the screen of the Android on the projector.
Does anyone know if this is possible, or if there is an "app for that"?
i dont think the nook is suited for that kind of activity, you would need something like the droidx, which has a mini-hdmi output, then you can get an app to mirror the screen.
im not really sure of the benefit of streaming an android screen to a projector when the whole computer is there available to you? if its an issue of video content, there are a lot of other solutions that would work, if nothing else, a usb cable to mount the nook and access the video files through a desktop application
I think there are vnc servers for Android phones. If you need this for any video, it'll probably suck.
The main use case is for during a presentation, to be able to see the slides as they are shown on the projector, and potentially see the notes and such. It would be a super bonus to be able to make notations/drawings, etc., during the powerpoint if that's possible.
a more hardcore solution
not sure if this would help, but I came across a similar problem where I was doing a presentation so I wrote an air app for my galaxy tab, and one for a mac running a projector and used the netconnection and netgroup classes to send position and navigation data from one to the other. Have a look at the RTMFP protocol

Lapdock, full resolution RDP?

Hello Everyone,
I have had my Droid 4 since launch and have been pretty much too busy for customization until now. I was able to get it rooted and everything thanks to the help of these forums, but there is one key feature I am hoping for that I have so far not been able to find a solution for anywhere here or at droidforums or with general Google searches.
I have a lapdock for my Droid, (stock Gingerbread but rooted) and I would love to be able to open a full resolution RDP session to my Windows 7 computer at home. I found that some people were able to install and run a Ubuntu image ( http://forum.xda-developers.com/showthread.php?t=1509836&highlight=lapdock ) however they still needed to access the GUI with a VNC client. As long as the GUI is accessed with an Android VNC app, when you use the app full screen on the lapdock it just interpolates the image (as it is running at the Droid 4's resolution of 960x540)
I know there was success with the Atrix with webtop2sd and installing applications like rdesktop to the Webtop environment itself. Has anyone tried this with the Droid 4?
If there are any other tips or tricks to get a full resolution RDP session running in Webtop I would greatly appreciate them. It also looks like once we get a ICS rom with HDMI support that it would probably work fine too, as it looks like Webtop 3.0 just gives a full resolution tablety interface instead of the desktop one, which is fine since all I want is full resolution RDP and if Android itself is full reolution it should work fine with an Android RDP client.
Thanks in advance,
Legomaniac
Stupid question, but have you tried a remote desktop app?
https://play.google.com/store/apps/details?id=com.xtralogic.android.rdpclient
i use this and it works fine, but i'm not using an docks or cables. Oh and there are free apps, i've just been using this one forever

I am well aware of the fact that there are RDP clients for Android, I have one installed and use it when I am not docked with the Lapdock. The problem is that all Android apps that are run fullscreen with the lapdock get interpolated from 960x540 to 1366x768. This produces a very fuzzy RDP session that isn't conducive to getting work done.
As I mentioned above, the Atrix community seems to have had luck with getting an ARM version of rdesktop running in Webtop. I am just hoping there is someone in the Droid 4 community who has had luck in the same area.

I have not tried this with a docking station, but .215 ICS leak's webtop works in higher resolution than mirror mode on both my TV and projector.
If you can't wait for the ICS version, I recommend installing the leak. I did and now this phone is all I wanted it to be. I'm not even going to bother installing the final ICS version anymore, because it'd only be risky in case they decide to block some features (especially important for me, being a European user).
Wait, so the .215 ICS leak supports HDMI out and works with lapdocks?
If so this is probably exactly what I need.

It supports HDMI with webtop 3 for sure, but don't have a lapdock myself for testing. Since lapdock is just HDMI + USB, I don't see any reason why it won't though!
Well, last night I installed the ICS .215 leak, and I must say, I really like Webtop 3.0! (plus ICS is just way sexier than Gingerbread)
Thanks for letting me know about HDMI working with the leak Sjaakbanaan. I had read somewhere in the forums that HDMI wasn't working, but i'm guessing that was quite an old post from when the very first ICS leak came out.
I love how apps change into "Webtop mode" which is essentially just their tablet layout. Being able to use all of the Android apps at full resolution on the lapdock is just awesome. I have a Microsoft Bluetrak USB mouse with a micro adapter that I just leave plugged into one of the Lapdock's USB ports. It is amazing! I am going to be using this setup on campus all through this year for taking notes and viewing slides in class (plus maybe some Facebook chat, lol)
Now the only issue is finding an RDP client for Android that doesn't need me to hold down the mouse button to move the cursor on the remote session. (since most So far I have only tried Teamviewer, which isn't actual RDP in the first place, i'm guessing there is a client somewhere in the Play market that is optimized for mouse input however.
Does anybody know of one of the top of their heads?
Thanks again Sjaakbanaan!
You're welcome!

I usually use an app called 'Remote RDP' for real RDP connections (it has a free version), but don't remember if it has the exact input mode that you like. On my Prime I usually prefer Splashtop (built-in version) instead of actual RDP

Is it Possible to Run Android 5.0 / Android TV on Raspberry Pi 2?

Hello i'm kind of new to this so please don't be to harsh .
To run Android TV, android 5.0 would need to be ported first thus me titling this "Is it Possible to Android 5.0 / Android TV on Raspberry Pi 2?" However my main subject / me making this post is to see if Android TV on Pi 2 is feasible.
I was thinking would be possible to run Android TV on the new Raspberry Pi? I ask this because the specs of the new Pi 2 are quite impressive and I can totally see this becoming popular as I can imagine a lot of people would go out and buy a Pi just to run android tv on it (me being one of them) . This would be great as not only would it provide a large install base for Android TV (which in turn up the developer support) it would make it so almost anyone can have a cheap chrome cast type of device with a functional GUI. I don't know if this is possible but doing some research I can't see any reason why it would't work and it would make for such a cool and inexpensive android tv box! :good:
Possible short comings would be:
Lag due to low clock speed
Lack of a remote (possible use of a bluetooth controller or a smart phone app to control the box using wifi)
Poor Gaming capabilities?
Probably a few more.

My research indicates this would be difficult, however, if a Chromecast type Media Center is what you're looking fo, I have good news. There are 2 OS downloads that are essentially XBMC ports for Pi 2.
http://www.raspberrypi.org/downloads/
I bought a Pi 2 today and am waiting for them to provide a delivery date. I intend to use it with one of these XBMC OS'S.

Probably the same conclusion as this:http://forum.xda-developers.com/hardware-hacking/raspberry-pi/rd-android-4-4-4-t2816952
XBMC for RPi already supports CEC through the HDMI... So most of your remote problems are solved there. A wireless Bluetooth keyboard/touchpad also solves the problem.
Yes, I can confirm that, I'm using osmc(aka raspbmc) for more that one and a half years and the performance is a quite good, even if I have allot of other things running on my pi...
CEC is supported, but be careful if you own a LG webos tv you should not us this, cause will slow down your tv and make it unresponsive, as far as I know only webos TVs are afected(2014 models).
But anyhow if raspbmc has a good performance on the old rpi B, I think should perform way faster on the new pi2.
I'm planning also to upgrade my pi..
From what is being reported on the Kodi forums, the Pi2 does very well with it. There is already a branch of OpenElec for it, and I think also one for RaspBMC/OSMC with a lot of the add-ons under recompilation during this week to give full support. But it's certainly getting full support from the dev community there, which is great.
But as noted even the Pi1 does very well anyway with Kodi, my overclocked B+ with OpenElec 5.0.1 works fine with it and no issues at all that I encounter day to day. Nice and smooth, and fully supports CEC from my (dumb) LG HDTV. And if you prefer, there's decent remote control for Android/iOS (Yatse) and web-based remote built into Kodi itself.
I'd certainly recommend it as an excellent alternative to AndroidTV.
The Android porting issue is the lack of graphics chip support
I'm wanting to see this as well, namely because Android TV also offers direct support for Netflix, Hulu, Plex, and others. While you can potentially get these with an xbmc based build, it will not work well with remotes.

The Pi supports CEC, so if you've got a suitable TV and the two are connected by HDMI then you're fine to go. I run my OpenElec set-up on my Pi1 using the remote of my LG dumb TV, and it's a doddle. It does have a wireless keyboard and mouse connected to it for it's other life as a Raspbian programming box for the kids (Scratch/Minecraft/Python) but I don't recall the last time I took up either when it was running in its OpenElec identity...
There is certainly an implementation of Plex for OpenElec. Not sure about the others, as I don't use any of them.

That isn't the problem. The remote itself works ok, and the device can see the events. The problem is the individual applications require different key bindings. I've done all of that crap where you configure different profiles and whatnot to bind different remote presses depending on the app, but it breaks all the time and maintaining it sucks balls.
Not doing that again. It's better just to have one cohesive interface that each app responds to identically. Android TV provides exactly that.
Two years ago, tried a hand at Android 2.3 on the Raspberry Pi after seeing an article on Cnet.
:silly:
Utterly terrible failure. They have then proceeded to pulled the article down.
YES, it's possible, GUI at 10-15fps with SW rendering. Slow but useable.

Actually, the problem is not that(the stack was adapted to GNU/Linux, see github.com/simonjhall/challenge but with memcpys), it is just that it depends on a Linux 3.0 kernel driver for full functionnality(HW layers). That driver is still not ported to modern kernels(the official RPi kernel is 3.19!)
It is fully doable. On IRC with the primary developer of Replicant, he said that porting Mesa/VC4 with adding Android support would take a few time with mostly buildsystem changes .(he ported llvmpipe)

I would like to use Android version 4.2.2 Jellybean! on my RP2+, Please understand i don't really quite understand everything you guys are saying, I just would like a straight answer, can it be done? My pi is version 2+ 512MB ram not the four core version.
THANKS!

No. Check back in 6 months, maybe someone will have Lollipop running on it by then!
Android TV on Raspberry Pi 2... That's a dream...
Well, I have a question...
Got the Raspberry Pi 2 with 512MB of ram, and I've tested the beta Android found here, and it's usable (just usable, it has lag, and many things can be done to it to became perfect). Why doesn't anyone try to port that Android on Raspberry Pi 2? Now we have a 900Mhz Quad Core CPU and double the ram...
Could you please provide mode details?
What' the issue with the Wi-Fi?
How is the general performance of the Lollipop?
Do you have Play Store installed?

This sounds incredible!!!
Nice ROM!
This Project is just great and now Open Source ! Would like to see a Build on our N6...
:fingers-crossed:
As a linux power user, I don't find this to be particularly exciting or useful.
What would be, would be open source multi-window multi-display ANDROID.
We can already run xorg as an android application, so if you want that, you just run it in your add-on second display. Makes "Maru" pretty much meaningless.
Can you explain a little more what you mean by add on second display

I'm doing this now by Using a micro USB MHL mini hub with a USB, HDMI and a SD Card reader, I than have a 4 port USB hub to increase the number of USB ports connected to that. Connected to these hubs are a monitor, mouse, keyboard, HD, Intuos Wacom drawing board (yep it works) and a AIO HP Laser Printer in which even the scanner works. Than using the fantastic app, "Second Screen", I change my desktops DPI to 240, which makes it look more like a traditional desktop OS and extend the desktop, instead of just mirroring, allowing me to use the Nexus 6's display along side a Samsung 24" 1080P monitor.
Since I'm now using Android N, I also have access to multi-window support, in which I enabled floating windows, a hidden feature in Android N. Which means my desktop system, again looks and feels like a normal desktop OS with apps in a individual windows.
This is extremely easy to do. I can't wait for a Chrome OS build though, now that Android has been integrated so I can have a proper desktop experience. Android only view when being used as a mobile and than Chrome OS when docked.

I'm calling BS on this. Unless I am completely mistaken the Nexus 6 does not even support MHL so this configuration you brag so openly about is either a total lie, or you are not running a Nexus 6.

I also call BS on those claims because the Nexus 6 doesn't support Slimport/MHL so I don't see how that would be possible.
