  • Have you tried wsl.exe --shutdown (which will reset WSLg as well) and trying again?
  • Can you reproduce this in another distro you have installed?

Thank you @sirredbeard for the answer.

For some reason, executing these commands will make GUI applications work again:

sudo umount /tmp/.X11-unix
sudo rm -rf /tmp/.X11-unix
sudo ln -s /mnt/wslg/.X11-unix /tmp/.X11-unix

Since I am using a wsl distro that I exported from a docker container - is this link something new that you have to set in order for wslg to work? (probably baked into the default distros that you can use?)

I could not reproduce it in another distro. In my debian wsl container GUI applications still work.

That is odd, I haven't experienced that with distros exported from existing Docker or Podman containers. Which one is it, if you don't me asking? Does it have X and related packages already pre-installed?

Hello,

I have similar problem with WSL Ubuntu 24.04 https://askubuntu.com/questions/1536740/wsl-ubuntu-24-04-display-is-not-working

I played around with DISPLAY variable but no way...

miroi@MiroPhenomII-X6:~/.export DISPLAY=:0.0
miroi@MiroPhenomII-X6:~/.xclock
Error: Can't open display: :0.0
miroi@MiroPhenomII-X6:~/.export DISPLAY=localhost:0.0
miroi@MiroPhenomII-X6:~/.xclock
Error: Can't open display: localhost:0.0
miroi@MiroPhenomII-X6:~/.

You're supposed to use collect-wsl-logs.ps1, which the bot gave a link to in "how to collect wsl logs".

Your log file isn't recognized because it has the wrong name.
