The Fix: Add a Sleep Delay
Try running the commands like this to give the Termux-X11 server 2 seconds to start up before launching Xfce4:
am start --user 0 -n com.termux.x11/com.termux.x11.MainActivity
XDG_RUNTIME_DIR=${TMPDIR} termux-x11 :0 -ac &
sleep 2
DISPLAY=:0 dbus-launch --exit-with-session startxfce4
Alternative: Step-by-Step Clean Start
If you still get an "X server already running" or "connection refused" error, a previous crashed instance might be blocking the port. Clear it out and start fresh:
- Kill any stuck processes:
pkill -f termux-x11
pkill -f xfce4
rm -rf $TMPDIR/.X11-unix
- Start Termux-X11:
am start --user 0 -n com.termux.x11/com.termux.x11.MainActivity
XDG_RUNTIME_DIR=${TMPDIR} termux-x11 :0 -ac &
- Launch the Desktop: (Wait a brief moment, then run this)
DISPLAY=:0 dbus-launch --exit-with-session startxfce4
If the issue persists, let me know if you are running this inside a PRoot/chroot Linux distro (like Ubuntu/Debian inside Termux) or directly in native Termux, so we can adjust the pathing!
