This article is about how to enable GPU hardware acceleration in Termux proot-distro by installing and running virgl server in Termux.
By enabling virlgl in proot, we will be able to play 4K60p videos and run 3D Linux games or Windows games (via Box86 + Wine) in proot.
SuperTuxKart, Glxgears
No root permission is required.
Testing device: Sony Xperia 5 II. Android 12. Snapdragon 865 (Adreno 650). RAM 8GB.
If you are confused , watch a video demonstration first (with subtitles)
Install Termux from F-droid
And setup Termux X11
Install a proot-distro with desktop environment.
I use Debian with XFCE4 .
Choose one method to install virglrenderer.
Method 1: Install Virglrenderer Android Install virglrenderer-android 1
pkg install virglrenderer-android
You can start virgl server by executing this command 1
virgl_test_server_android &
Method 2: Compile Virglrenderer with Zink P.S. The following steps are done in Termux, not inside proot-distro.

You can start virgl server by executing this command 1
MESA_NO_ERROR = 1 MESA_GL_VERSION_OVERRIDE = 4.0 GALLIUM_DRIVER = zink virgl_test_server --use-egl-surfaceless
Note: virgl server may be broken after upgrading Termux packages. (You will see errors like libEGL warning: DRI2: failed to create dri screen in terminal) If so, recompile everything in Part 3 and try again.
Start virgl server in Termux.
Launch Termux X11 app, keep it opening in the background. Go back to Termux, start Termux X11

export DISPLAY = :0
termux-x11 :0 &
Swipe from left edge, clcik New Session to open a new terminal. Log into proot-distro as user and mount Termux’s /tmp to proot. 1
proot-distro login debian --user user --shared-tmp
Then start XFCE session 1
2
export DISPLAY = :0
dbus-launch --exit-with-session startxfce4 &
Open terminal emulator in XFCE desktop. Run applications with two parameters: GALLIUM_DRIVER=virpipe MESA_GL_VERSION_OVERRIDE=4.0 to use virgl. Note some applications may crash when MESA_GL_VERSION_OVERRIDE=4.0 is used.
For instance, to run Minetest with virgl：
1
GALLIUM_DRIVER = virpipe MESA_GL_VERSION_OVERRIDE = 4.0 minetest
The FPS of glxgears is higher when virgl enabled.
After enabling virgl, Minetest FPS grows from 10 FPS up to 20 FPS.
VLC with virgl is capable of playing 4K60p videos.
SueprTuxKart becomes playable after enabling vrigl.
The FPS of WebGL Aquarium doubled after enabling virgl. (You need to force enable WebGL in about:config)
Setup a chroot environment, for exmaple chroot Ubuntu with XFCE4
Set SELinux to Permissive
Start Termux X11 APP. Go back to Termux, execute: 1
XDG_RUNTIME_DIR = ${ TMPDIR } termux-x11 :0 -ac &
Mount Termux’s tmp to chroot’s tmp directory 1
2
export CHROOT_DIR = /data/local/tmp/chrootubuntu
sudo busybox mount --bind $PREFIX /tmp $CHROOT_DIR /tmp
Log into chroot. Start XFCE4 1

3
chmod -R 777 /tmp
export DISPLAY = :0 PULSE_SERVER = tcp:127.0.0.1:4713
dbus-launch --exit-with-session startxfce4 &
Run apps with virgl 1
GALLIUM_DRIVER = virpipe MESA_GL_VERSION_OVERRIDE = 4.0 minetest
Install Box86 + Wine in proot-distro.
Start virgl server in Termux.
Run box86 with GALLIUM_DRIVER parameters：
1
GALLIUM_DRIVER = virpipe MESA_GL_VERSION_OVERRIDE = 4.0 box86 wine AIR.exe
“Undertale” works well with virgl enabled.
Also visual novel “Air”
