[Bug]: termux-x11 exits instantly, silently and with 0 exit code #333

Closed drjaska closed 1 year ago

drjaska commented 1 year ago

Problem description

Attempting to run a termux-11 server in proot-distro doesn't provide any x11 server but exits instantly, without any stdout nor stderr prints and with 0 for its exit code.

┌[@localhost]
└[0] ~ > proot-distro login debian --shared-tmp --user drjaska
┌[drjaska@localhost]
└[0] ~ > termux-x11 :1 -xstartup "xclock"
┌[drjaska@localhost]
└[0] ~ >

twaik: Possibly proot-distro does not bind some android pathes needed by app_process, you should open issue in proot-distro's repo.

What steps will reproduce the bug?

I don't know if the issue is reproducible with these but these were my steps:

doesn't exit instantly and provides connectable x11 server with the termux:x11 mobile app

these exit instantly, without any stdout nor stderr prints and with 0 exit code

What is the expected behavior?

termux-x11 :1 -xstartup "xclock" should not exit instantly and should provide a x11 server instead of exiting instantly.

Try starting termux-x11 again and immediately capture logcat output. Post the output here.

drjaska commented 1 year ago

I ran the termux-x11 :1 -xstartup "xclock" command a few times in proot-distro and adb log section for kinda that timeframe looks like this

I need the complete log

sylirre commented 1 year ago

And try to not start PRoot Distro from Termux:Widget. Just open Termux, start PRoot Distro and then termux-x11.

sylirre commented 1 year ago

I can't find anything related in your log and can't reproduce the issue on my own:

screen

I suggest few more things for troubleshooting:

drjaska commented 1 year ago

Ah, it works in bash but not in zsh. Try changing your login shell from bash to any other shell with for example install zsh and run chsh -s $(which zsh) and log out and back in.

I looked at the env vars I had with bash and with zsh and found these notable differences.

Pasting those env vars to /etc/environment is a working band-aid fix too.

sylirre commented 1 year ago

Yes, /etc/environment seems to work. Need to do some testing to see whether using this file is reliable enough to replace /etc/profile.d across different distributions.

As far I know /etc/environment is loaded by PAM, but not all distributions use PAM for su and login utilities.

Syliree, Can You Ask?

Fixed in the latest git.
