Im running a userinit file for the cyanogen 3.91 rom and if tried to run it with now success. it just shows 000 on the swap when i run free. and when i try to run cat /proc/ramzswap it says that no such directory exists,
this is the userinit.sh

yeah dude im getting the same problem. Ive asked everywhere and no one can help. the only difference i notice are the two lines (exit; # eof) at the end of yours.
EDIT:
DUDE, just got it to work, this is what to do:
go here: http://forum.xda-developers.com/showthread.php?t=537236
download the text file.
open the text file delete everything and paste this in:
Code:

save it and close it
rename it userinit.sh and type this in adb:
Code:
adb push userinit.sh /system/sd
adb shell chmod 755 /system/sd/userinit.sh (not sure if needed being safe)
adb shell reboot
hope that helps
did you get it to work on 3.91?
ive tried everything and still swap is 0 0 0 0
I'm not an expert in the whole compcache thing I haven't followed it but doesn't "free" in terminal show swap, not compcache? I believe "cat /proc/ramzswap" shows compcache compression..

"free" shows the swap file total, used and free. ramzswap goes more indepth

Compache DOES NOT WORK ON 3.9.1
Title pretty much says it all.
In the rom's thread it says "NOTES:Swap is linux-swap by default. Edit the user.conf in /system/bin to change swappiness etc. Compcache modules built with the latest source are included if you want compcache or compcache with backing etc. Run sh /system/bin/swap -s to check swap status and other mod values." I entered sh /system/bin/swap -s in the terminal and it says that system and user is set to 30. What do I enter to change it?
Also, just curious.... When I run sh /system/bin/swap -s what should it say when it lists the CPU's powersave_bias?

To change it. You would just pull that file change the 30 to whatever you want your swappiness to and then push it back. But honestly I would prolly just leave it at that.
How to install ubuntu on the Droid 4
Note to mods: this thread is a branch off of this thread
Huge thanks to zacthespack for creating the ubuntu installer app and original boot script and to zeroktal for modifying the script to work on the D4 and helping me get it working on my device.
I decided to take my experience in setting this up and put it into a how-to so that others could enjoy the experience of having ubuntu on the Droid 4. If zackthespac or zeroktal have any problems with me making and putting this guide up, please let me know and I will remove it.
Knowledge Required:
working knowledge of command line
working knowledge of vi
OR the ability to learn how to use both
Tools Required:
A rooted Motorola Droid 4
BusyBox (Android Market)
Terminal Emulator (Android Market)
Android VNC Viewer (Android Market)
Ubuntu Installer App (Android Market)
zeroktal's ubuntud4.zip file (attached to this post and mediafire)
Vi Cheat Sheet (lagmonster.org)
Step by Step:
Install BusyBox, Terminal, and Android VNC Viewer
Install and run Ubunutu Installer App
Follow the on-screen instructions and click next
Download either the Small or Large image to your phone, (use zeroktal's ubuntud4.zip file instead of the boot script provided in the guide) after the image downloads (will take a while because the file is HUGE) click next
For this screen, the instructions differ from the app.
1. With your D4 plugged into your PC in USB Mass Storage, create a directory (folder) called ubuntu in the EXTERNAL sdcard's root*
2. Extract the image you downloaded to that directory
3. Download and extract the attached .sh (ununtud4.zip) to that directory
4. Disconnect your phone from your PC
5. Open terminal and run the following commands:
su [ENTER]
mount -o remount,rw,exec,suid /dev/block/vold/179:1 /mnt/sdcard-ext [ENTER]
cd /mnt/sdcard-ext/ubuntu [ENTER]
sh ubuntud4.sh [ENTER]
960x540 [ENTER]**If you get an error message: ubuntud4.sh: 45: syntax error: end of file unexpected (expecting "then") see troubleshooting section below.killall -TERM Xtightvnc [ENTER]
vncserver :1 -geometry 960x540 [ENTER]**6. Open androidVNC app and enter the following settings:
Nickname: Anything you want
Password: ubuntu
Address: localhost
Port: 5901
Color Format: 24-bit color (4 bpp)
7. Hit connect
8. Hit your menu soft button and then set input mode to touchpad
9. You have ubuntu on your Droid 4!
To "shut down" ubuntu:
press the menu button, select disconnect in VNC
In terminal type this command 3 times (terminal will close itself when you are done):
exit [ENTER]
To "start up" ubuntu again:
Follow steps 5-8 above
Troubleshooting:
If you get the error message: ubuntud4.sh: 45: syntax error: end of file unexpected (expecting "then") you are about to have fun with vi at the command line.
Do the following from inside terminal:
su [ENTER]
cd /mnt/sdcard-ext/ubuntu [ENTER]
vi ubuntud4.sh [ENTER]If you see ^M or ^ at the end of any line (remember to scroll all the way to the right to see the end of long lines) remove it. once you do that, everything should work just fine. (See the Vi Cheat Sheet above for help with Vi)
Note: Vol Up + E is [ESC] by default in this terminal emulator
Notes:
* It does not have to be on the external SD, but if you put it on the internal SD you will have to modify things as needed-- if you dont know what needs to be changed, just put it on the external SD.
** Screen size can be whatever you want it to be, but 960x540 is the size of the D4 screen.
*** This is a fairly involved process... especially when it comes to editing the .sh file in vi things can get very frustrating and hard, but just take your time and you will get it. As always, doing anything with root access on your phone, especially on the command line has risks. I am not responsible if anything goes wrong with your phone... proceed at your own risk!

I actually got it up and running on my internal sdcard partition. Pretty much just have to modify the Mount remount command, and a few lines in the script.
Here's the original command
Code:
mount -o remount,rw,exec,suid /dev/block/vold/179:1 /mnt/sdcard-ext
And the modified one
Code:
mount -o remount,rw,exec,suid /dev/block/vold/179:57 /mnt/sdcard
Only things you have to change are the device location(179:57) and mount location(drop the -ext after sdcard)
Now, after that you also have to modify the script a bit. Just go through it, and anywhere that you see sdcard-ext, drop the -ext off the end.
thanks for putting that up for everybody! like i said, if you know what you are doing its not a hard swap to make.
Is anyone else getting just a gray screen when they remote in? What could be causing this?
i had that same problem at first... did you use zeroktal's ubuntud4.zip file? or did you use the ubuntu.sh file included in the app?
I used the sh file included. I did however fix the problem, when mounting at the start i confused vold with void. I did not get the file system mounted properly. This method does work!! however I am currently trying to get bash on my droid to replace sh as the shell. I've checked the forums but have not found anything yet about someone installing bash on the droid 4. With no way for nandroids I feel i should wait before I kill sh.

Also save the follow lines between ### as remount.sh on your system partition. Then chmod 755 /system/remount.sh. Now you can just run run from a terminal /system/remount.sh and voila it remounts correctly and starts ubuntu(with the above fixes). Im still working on the unmounts.

QUESTION:
After I delete all the ^M and ^ what do i do next? I try to hit the command ":x" to exit and save changes but it just creates another line. Also when I press VOL UP + E to escape nothing happens.

In vi, the command to save and exit is :wq (probably short for write and quit).
remember, read up on the vi quick-reference guide: http://www.lagmonster.org/docs/vi.html
OK I fixed it but now its not letting me connect with androidVNC. All the settings entered is correct but when I try to connect it says:
"VNC connection failed!" localhost/127.0.0.1:5901 - Connection refused"
ok, i've gone thru this a few times (slowly and deliberately) and must be missing something...the directions seem pretty straightforward! here's what i know...
busy/terminal/vnc are all installed
small 2.5gb image is unzipped in /sdcard-ext/ubuntu directory
the attached .sh file from page 1 is in the same directory
i removed all ^M using vi
but when I try sh ubuntud4.sh i get an error...
"mkdir failed for /data/local/mnt/ubun, No such file or directory"
(plus a few other errors)
should the directory be "ubun" or "ubuntu"? am I typing something incorrectly?
copy and paste new script
Copy and paste the new scripts I posted. They will fix your problem. Remember to use the remount script from /system/ the rest will work perfectly if you are root. I'll check back later on your progress.
Ok, well I started from scratch (deleted both .img and .sh files) and it's still not working.
I have all the apps installed (and yes rooted, SU works just fine)
I used Ubuntu Installer app to download the image zip (tried both the large and small img)
I downloaded the .sh file from the first post
The /sdcard-ext/ubuntu/ folder now has two files: "ubuntu.img" and "ubuntud4.sh"
All ^M characters have been removed from .sh file
Still no joy...
Ideas? What am I missing?
In terminal, I can set SU permissions and the mount/cd commands work just fine...it's the last sh command that spits out a bunch of errors about not being able to create/find the directories.
I'm going to format the sdcard and try again...any help is appreciated.
Update: Even after re-formatting the SD and following the steps exactly, no luck!
Did you remember to remount the sdcard with exec and suid permissions?
Andbuntu will work much better than this method. It works on every single phone with modification to the "environmental variables".
http://code.google.com/p/andbuntu/
Follow the directions in the script to make the process much easier than the first post.
instructions:
generate an image with rootstock on an ubuntu computer.
put it on /sdcard/ubuntu/ubuntu.img
run the script on your phone with "sh /path/to/script"
Here is the script. http://andbuntu.googlecode.com/svn/trunk/uboot
Also, run "firstRun" to make things like terminals work properly.
Adamoutler: That didnt work for me. The permissions were incorrect on the mounted partitions.

Dear Community, dear Developers outside..
I'm using Magisk 14.0 on a Redmi Note 4 Snapdragon and super satisfied with it.
I just want to make simple changes like changing the lowmemorykiller minfree parameters - just like an init.d script in Kernel Adiutor..
Most of the commands are effective - but some of them are not..
This is what I want to apply for example:
chmod 666 /sys/module/lowmemorykiller/parameters/minfree
chown root /sys/module/lowmemorykiller/parameters/minfree
echo '7283,14566,21849,28928,36415,43698' > /sys/module/lowmemorykiller/parameters/minfree
..but does not work..
But these, for example.. these are working just fine:
echo '30' > /proc/sys/vm/swappiness
echo '0' > /sys/module/lowmemorykiller/parameters/enable_adaptive_lmk
echo '80' > /proc/sys/vm/overcommit_ratio
echo '400' > /proc/sys/vm/vfs_cache_pressure
echo '2430' > /proc/sys/vm/extra_free_kbytes
echo '4096' > /proc/sys/kernel/random/write_wakeup_threshold
echo '1024' > /sys/block/mmcblk0/queue/read_ahead_kb
echo '0' > /sys/block/mmcblk0/queue/iostats
echo '1' > /sys/block/mmcblk0/queue/add_random
echo '1024' > /sys/block/mmcblk1/queue/read_ahead_kb
echo '0' > /sys/block/mmcblk1/queue/iostats
echo '1' > /sys/block/mmcblk1/queue/add_random
swapoff /dev/block/zram0 > /dev/null 2>&1
echo '1' > /sys/block/zram0/reset
echo '0' > /sys/block/zram0/disksize
echo '1' > /sys/block/zram0/max_comp_streams
echo '524288000' > /sys/block/zram0/disksize
mkswap /dev/block/zram0 > /dev/null 2>&1
swapon /dev/block/zram0 > /dev/null 2>&1
echo '4096' > /proc/sys/kernel/random/read_wakeup_threshold
echo '4096' > /proc/sys/vm/min_free_kbytes
echo '0' > /proc/sys/vm/oom_kill_allocating_task
echo '90' > /proc/sys/vm/dirty_ratio
echo '70' > /proc/sys/vm/dirty_background_ratio
I do know that all I have to do is to put my script to one of these dirs - depending on when I want to run the scripts:
/magisk/.core/service.d
/magisk/.core/post-fs-data.d
But, as I mentioned - most of them has effect, some of them has no..
Any comment, any suggestion is more than appreciated.
Thank you!
[SOLVED] - solution is in post #5
Desperate bump..
I searched for help docs for service.d and post-fs-data.d but counldn't find them, can I ask you when each folder is executed, also does the scripts inside them must have .sh extension or not ?
I want to restart my systemui after boot complete, can you tell me if this script is ok ?
Code:
#!system/bin/sh
sleep 20
su
pkill -l TERM -f com.android.systemui
ps : the pkill command works fine after an "su" in terminal emulator
sorry for the offtopic !
@sheraro
https://github.com/topjohnwu/Magisk/blob/master/docs/README.MD
First of all: the solution for my issue was a simple sleep 30 in the services.sh to delay the start.. and I used an auxiliary file as well to make the changes (called from services.sh with 30sec delay, copied with the update-binary file directly, set permission to 0777 via config.sh) after that is all started working..

So, second thing, @sheraro, I think you should delete the command su from your script because Magisk scripts are running as root anyway and if you issue su command it will start a shell with elevated privileges - an interactive shell, not what you want here, a sudo like command.. it works in the terminal because it is interactive but in the shell script if you start su it starts an interactive shell and it halts your script because it won't exit the shell you started.. and the next command will never run.. if you know what I mean.. but you don't need it anyway, because - as I mentioned - it is running as root anyway. +1: The syntax of the shebang is bad in your example, it is missing an exclamation mark. Can you re-test it like this:
Code:
#!/system/bin/sh
sleep 20
pkill -l TERM -f com.android.systemui
exit 0
.sh extension is not needed, the thing is: you have to set the correct permission in the config.sh like this:
Code:
set_permissions() {
# Default permissions, don't remove them
set_perm_recursive $MODPATH 0 0 0777 0777
[..omitted..]
Thing is: the files must have execute priv. and you can execute them like
Code:
$MODDIR/./desiredfilename
in the services.sh script.
Hope this helps.

Reading your comment I think you are not developing a Magisk module, do you?
I do and this is why you have no idea where is config.sh, services.sh and the others I think.
If you just want to have some kind of "init.d script" support and run the script in your own phone *only* then your script should be in the folder /magisk/.core/service.d and it should have execute permission. That's all what you need - probably the sleep 20 is not enough, increase it to sleep 30 for instance.
If this is still not enough info I would suggest to read the Magisk documentation thoroughly (linked in post #4) and if you still stuck I suggest you to open your own thread, describe your problem thoroughly (what is your goal? what would you like to achive? how did you already try? what is happening but should not or not happening but you think it should happen? you know what I mean..) and ask the community. Probably you will be able to solve your issue in minutes/hours.
I changed it to sleep 100, same problem, you're right I should create a new thread for this.
I have a theme installed that mimics oreo style, but the systemUI is not themed until it's restarted, so I thought about a script executed after boot, anyway thanks for your help
It seems that sleep will delay the run of other modules' service.sh. is there any solution that will not affect other module?

I don't experience this behavior - what you described is the post-fs-data behavior.
I did the trick with a separate ("auxiliary") file and tried to explain how in post #5 but let me try again:
- created a file in the module's common folder (I gave the name `tweak`)
- this file starts with a shebang (it's a script..) and continues with a sleep 30 then comes my commands..
- then copied the file from the module to the Magisk module directory into /magisk/$MODDIR with the module file META-INF/com/google/android/update-binary (I added it to the copy section, manually.. I know, I know, it should work automagically anyway, but did not work and I was fed up with the coding, so hardcoded it.. sorry)
- I set the default file permission to 0777 in config.sh (yes, 0777, this is loose AF but works.. and I don't really care, the file contains code that can make the device *better* and has no suid bit set, so there is only little to no room to harm anything..)
- then I included a call in my module's common/service.sh like $MODDIR/./tweak to start my script
- when the tweak script starts it will start with the sleep 30 so implements the delay.. BUT!
- Because services.sh files from the modules are called parallelly by Magisk (by default, by it's nature, by it's code.. you got it) my module does not delays others - but still has the delay.
Hope this helps.

Pleased to help you - but honestly, if the only task you need is to kill and restart systemUI then I would do it via init.d script run by an app that mimics init.d scripting, or using a kernel that supports init.d scripts (if only you want to use that theme). It's just less complex for you I think, but honestly, a simple script file that has execute permission in /magisk/.core/services.d/ gives you 100% the same solution.

- I set the default file permission to 0777 in config.sh (yes, 0777, this is loose AF but works.. and I don't really care, the file contains code that can make the device *better* and has no suid bit set, so there is only little to no room to harm anything..)
- then I included a call in my module's common/service.sh like $MODDIR/./tweak to start my script
- when the tweak script starts it will start with the sleep 30 so implements the delay.. BUT!
- Because services.sh files from the modules are called parallelly by Magisk (by default, by it's nature, by it's code.. you got it) my module does not delays others - but still has the delay.
Hope this helps.

I have my script in starting in .Core. Maybe that's the problem

..then it is in the wrong dir.. it is clearly described in the Magisk documentation.
I have researched a bit. I think you can use getprop sys.boot_completed to check if boot is completed. We should run init.d scripts after boot is completed instead of just wait for 30/100 seconds.
I place all my init.d scripts I want to run in /magisk/.core/service.d/init.d.
Then, I have a service.d script [exec_init_d.sh] in /magisk/.core/service.d. Magisk will run exec_init_d.sh when boot.
exec_init_d.sh will wait for sys.boot_completed and run all the files in /magisk/.core/service.d/init.d after boot completed
exec_init_d.sh
Code:
#!/system/bin/sh
# Please don't hardcode /magisk/modname/... ; instead, please use $MODDIR/...
# This will make your scripts compatible even if Magisk change its mount point in the future
MODDIR=${0%/*}
# This script will be executed in late_start service mode
# More info in the main Magisk thread

Warning: Using dd incorrectly can easily kill your smartphone
If you make a mistake in the commands you can erase the data on your memory card or erase one of the eMMC partitions altogether
After all this procedure will delete all the data on /internal_sd/ and you will not be able to store files on it
And now for the tutorial: I find these 96 MB in /internal_sd/ not very useful so I decided to use them for swap and it was successful
You need a kernel with swap and init.d and of course a root
That's all in the CM11 RC5. I don't know about other kernels or ROMs.
1) Download internal_sd_swp.img from the attachment
2) Put it somewhere on your smartphone
3) Run adb shell or some terminal on your smartphone
4) Do su and allow the request from the application Superuser or SuperSU
You should see # at the beginning of the line
5) Type
Code:
dd if=/patn/to/img/internal_sd_swp.img of=/dev/block/mmcblk0p32
(instead of /patn/to/img/ it should be where you put .img, if /data/local/ it will be /data/local/internal_sd_swp.img if /sdcard/ then /sdcard/internal_sd_swp.img etc)
6) Make a file 09swapon in /system/etc/init.d/ and type the following
Code:
busybox mkswap /dev/block/mmcblk0p32
busybox swapon /dev/block/mmcblk0p32
echo 100 > /proc/sys/vm/swappiness
7) Reboot and enter the
Code:
free
command and if successful the swap will not be 0
If you want it back the way it was, download internal_sd.img from the attachment, dd it like before and remove /system/etc/init.d/09swapon
