setting up termux-x11

guide for setting termux-x11 for udroid GUI

termux-x11 is a termux addon providing Android frontend for xwayland. It uses the Wayland display protocol, which is aimed to become the successor of the X Window System. Note that it is not a fully-fledged Wayland server, it's like an X system in Wayland.

1. How does it work?

Through its companion package, the executable creates a socket through $XDG_RUNTIME_DIR in the Termux directory by default.

The Wayland sockets are the way for the graphical applications to communicate with. Termux X11 applications do not have Wayland support yet, this kind of setup may not be straightforward and therefore additional packages should be installed in order for X11 applications to be run in termux-x11.

2. Requirements

• Termux from f-droid or termux-dev builds

• termux-x11 app from GitHub releases page *

apt install termux-x11-nightly -y

4. Starting termux-x11 app

Start the termux-x11 app and use this command in termux to start the x11 server

termux-x11 :0 &

:0 is the display number and & is used to stop termux-x11 from locking the terminal

5. Using termux-x11 with UDROID

udorid launch script takes care of mounting the termux-x11 default socket directory to the suites tmp directory, you just have to export the DISPLAY variable to the correct display address and run the application/Desktop environment to show the GUI in termux-x11
