XWayland in termux

INTRO

Termux started working back on their archived project termux-wayland. and its working fast enough even with Desktop Environments like KDE plasma
here is my guide for setting up fastest linux GUI environment for termux ( faster that VNC ).

Setting up termux

Official f-droid termux may not work for this so get termux from https://github.com/termux/termux-app/actions

xwayland ( binaries for wayland ) & termux-x11 ( scripts to start termux-x11 app from termux ) are in x11-repo

pkg install x11-repo -y
pkg install xwayland termux-x11

Setting termux is done ✌️

Installing Termux:Xwayalnd app

for now, this app is available here

or get my old snapshot of termux-x11 so download and install it

Using Termux:Xwayland to run `proot-distro` Linux

assuming you installed ubuntu with proot-distro with xfce4 installed

in your termux execute

termux-x11

this starts termux-x11 with all the required ENV variables

now back to termux and login to distro you like ( for this tutorial let's say it is udroid proot-distro ) with --shared-tmp option. by default Wayland socket in stored in termux $TMPDIR so using --shared-tmp bind /tmp in proot linux to $TMPDIR of termux app

proot-distro login udroid --shared-tmp

Now export DISPLAY environment variable with value :0, termux-x11 starts display at :0 ( default )

export DISPLAY=:0

finally start your Desktop Environment ( xfce4 works better )

dbus-launch --exit-with-session startxfce4

That's all now if you open minimized Termux:x11 app you see xfce4 running
