termux scripts

An attempt to automate the process of setting up a minimal proot xfce DE inside termux with Hardware Acceleration and Pulse Audio support.

Usage

• Download Termux and Termux:Boot from F-Droid
• Open Termux and run following command:

  source <(curl -sSL https://raw.githubusercontent.com/Vikasg7/termux-scripts/main/scripts/1-install-proot-distro.sh) debian
  

• Restart the phone
• You should be able to ssh or vnc into proot-distro using localhost or DNS Server IP (192.168.1.x)

  ssh 192.168.1.x -p 8022
  

  vncviewer -passwd your_password 192.168.1.x:1
  

  Note: 192.168.1.x can be replaced with localhost
• termux-x11 is also supported. Disable vncserver by commenting out the following line in .termux/boot/startup:

  proot-distro login debian --user vikas --no-kill-on-exit --shared-tmp --bind $HOME/storage:/mnt/Phone -- /bin/bash -c 'rm -rf /tmp/.X* && vncserver -autokill yes'
  

  and uncomment following line.

  # proot-distro login debian --user vikas --no-kill-on-exit --shared-tmp --bind $HOME/storage:/mnt/Phone -- /bin/bash -c 'termux-x11 -xstartup "bash .vnc/xstartup" :1'
  

• Restart the phone and open termux-x11 app, you should see the desktop.

Hardware Acceleration

By default opengl drivers are enabled. You can switch to zink(vulkan) by

• commenting out the following line in .termux/boot/startup

  virgl_test_server_android &
  

  and uncommenting the following line

  # MESA_LOADER_DRIVER_OVERRIDE=zink GALLIUM_DRIVER=zink ZINK_DESCRIPTORS=lazy virgl_test_server --use-egl-surfaceless --use-gles &
  

• and commenting out the following line in .vnc/xstartup inside proot-distro

  export GALLIUM_DRIVER=virpipe
  

  and uncommenting the following line

  # export GALLIUM_DRIVER=zink
  

• Restart the phone

Avoid killing background processes

• Enable USB/Wireless Debugging, Install android-tools on your PC and Connect your device to a PC with adb.
• Persist adb config on reboot

  adb shell "/system/bin/device_config set_sync_disabled_for_tests persistent"
  

• Disable Killing Phantom Processes. Here is the Explanation.

  adb shell "/system/bin/device_config put activity_manager max_phantom_processes 2147483647"
  

TODO

• figure out audio
• test Hardware acceleration using glmark2
