[Bug]: Distrod causes X11 to not work under wslg. #56

Closed dyharlan closed 2 years ago

dyharlan commented 2 years ago

Describe the bug

XWayland under WSLg doesn't work anymore when installing Distrod. It seems like systemd is ignoring the x11.conf that allows the distro to bind-mount /mnt/wslg/.X11-unix to /tmp/.X11-unix

Otherwise, wayland apps run fine.

I am using systemd 251.2-1 Also, I'm using the Windows Store version of WSL.

Steps to reproduce

  1. Install distrod
  2. Run a X11 application under WSLg.
  3. The application complains that it cannot find :0.

Expected behavior

For .X11-unix to be properly bind-mounted in /tmp and run XWayland apps.

Windows version

Microsoft Windows 11 21H2 [Version 10.0.22000.708]

Linux kernel version

5.10.102.1-microsoft-standard-WSL2

Distro

ArchWSL 22.3.18.0

How did you install that distro?

Enabled distrod in an existing WSL2 distro

I also run into the same error here.

This issue seems specific to the latest version of WSL on MS Store (0.60.0), where it uses a bind mount to handle /etc/.X11-unix instead of symlink previously. (See WSL 0.60.0 release page)

For now, a workaround is to downgrade WSL to previous version, versions before 0.60.0 works with distrod without this issue.
