[twaik]

Yes. It is already in TODO list.

yups its worked fine now :)

but got new error when i was trying to check for the other bug (no display and only a blank screen on x11 app when i exited from the x11 app) which is the new error is this error:

termux-x11

i closed the x11 app and then type termux-x11 and popup show Service was created, but in termux showed that error.

That is Xwayland error. You should erase $TMPDIR and then create it again

rm -rf $TMPDIR
mkdir -p $TMPDIR

And then force-stop com.termux application in Android settings.

so, am trying to test for the other bug which is "no display on x11 app when i closed the x11 app" but unfortunately got that error.

[twaik]

Can you please try again and post here new logs?

That is Xwayland error. You should erase $TMPDIR and then create it again

rm -rf $TMPDIR
mkdir -p $TMPDIR

ok now it worked again :) so i've to always remove the TMPDIR and recreate it and force-close then termux-x11 when i encountered that error?

i was trying to use x11 app for displaying proot-distro archlinux and its successful now :)

but what am really want to do is using GPU acceleration thru the x11 app is that possible? i saw vulkan-tools in apt upgrade, what is it? and btw how to resize the x11 app so that it doesnt looks small in my device? when i use XServer XSDL/VNC Client i can do that.

I can explain why this happens and you will understand why I adviced this... Shortly. When Xwayland or any other Xserver starts it creates lockfile somewhere in $TMPDIR (do not remember file name), opens Unix socket in $TMPDIR/.X11-unix/X0 (for DISPLAY=:0) and one more socket on TCP port 6000 (for DISPLAY=:0). Usually those are being removed after finishing Xwayland/Xserver process, but sometimes something goes wrong and it does not happen. I do not know why but rm -rf $TMPDIR/ (to clean Unix socket and lock file) did not work for me, only rm -rf $TMPDIR; mkdir -p $TMPDIR. Cleaning TCP socket is a bit harder, even after killing Xwayland process it was unavailable, but I succeed to clean it by force-stopping com.termux.

Nice.

but what am really want to do is using GPU acceleration thru the x11 app is that possible?

No. Prooted environment can not use Android components.

i saw vulkan-tools in apt upgrade, what is it?

Have no idea... Sorry.

and btw how to resize the x11 app so that it doesnt looks small in my device?

There is no way in current versions... But you can try to change scale in DE. You can see how to do this in KDE in Readme.md
