WSL logs:

WSL dumps:

No response

Expected behavior:

Should be able to run Xserver; also, per the instructions at the github troubleshooting link (above), I should be able to create the link for the Xserver, i.e.
sudo rm -r /tmp/.X11-unix
ln -s /mnt/wslg/.X11-unix /tmp/.X11-unix
Both commands should work.

Actual behavior:

The rm command fails with: rm: cannot remove '/tmp/.X11-unix': Device or resource busy, and
the ln command fails with ln: failed to create symbolic link '/tmp/.X11-unix/.X11-unix': Read-only file system,
although ls -la /tmp/.X11-unix shows

total 4
drwxrwxrwx 2 root root   40 Jan  2 19:58 .
drwxrwxrwt 7 root root 4096 Jan  2 20:08 ..

which doesnt appear to be a read-only filesysytem.
BTW sudo ln -s /mnt/wslg/.X11-unix /tmp/.X11-unix fares no better:
ln: failed to create symbolic link '/tmp/.X11-unix/.X11-unix': Read-only file system

In my case, I get this message when trying to open Cypress:

Other GUI applications are not openning but don't output any message.

EDIT:
In my case, the problem only occurs with ArchWSL. Installed Ubuntu and had no problems.
This is the X-related info that is in Ubuntu (which works fine):

I used VcXsrv months (years?) ago and do not have it installed anymore, but seems like it's still messing up WSLg somehow

what linux distro are you using?

kiocosta · 2024-01-10T14:52:41Z

As suggested in this issue, the issue is solved by adding export LIBGL_ALWAYS_INDIRECT=1 to ~/.zshrc (or ~/.bashrc if you use bash) and then running source ~/.zshrc so the changes take effect.

SimonCrouzet · 2024-01-20T13:24:14Z

When trying the fix proposed above, I realized that I still had some remaining of my previous VcXsrv install in my .bashrc file:

export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2; exit;}'):0.0
export LIBGL_ALWAYS_INDIRECT=1
sudo /etc/init.d/dbus start &> /dev/null

I removed the first and third line, and everything is working well now

Tried this too, though I wasn't using ArchWSL, but still X11 doesn't appear to be running and the link fix still fails as described in the original issue.

I'm having exactly same issue as @Cteljr , same versions.
I tried fresh installing wsl2 and distros with same results:
X apps dont work, xeyes/xcalc: "cant open display :0" -or- "Missing X server or $DISPLAY"
I tried "export LIBGL_ALWAYS_INDIRECT=1" - not working...
Wayland apps do start normal (chrome/nautilus/gedit) but sometimes graphic garbles up, hinting at graphics driver problems

In /mnt/wslg/weston.log I see:
[16:58:42.737] Spawned Xwayland server, pid 23
[16:58:44.758] xserver crashing too fast: 134

Researching earlier reports of xserver crashing too fast in wsl2, turns up old intel graphic driver bugs.
I have a 2 GPU setup on an intel tiger lake i7:

Intel® Iris® Xe Graphics
Nvidia RTX 3050
both with absolutely latest drivers (so I think), looks like the intel graphics driver crashes out on wsl2's xwayland

A solution is to get wsl2 to work with xming instead of wsl2's own xserver: install xming and add these to your .bashrc:
export WSL_WINDOWS_HOST=cat /etc/resolv.conf | grep nameserver | cut -d ' ' -f 2
export DISPLAY=$WSL_WINDOWS_HOST":0"
That worked for me, but it seems you dont get the same fancy window integration

wimvanspringel · 2024-02-15T17:02:49Z

Update:
Turns out I wasnt using the latest Intel Graphics drivers!
Intel's Driver Support Agent forced it to the old 27.20.100 latest manufacturer (MSI) supplied version.
Downloading latest install directly from intel's support site forced the install of latest 31.0.101 version
[edit] MS windows keeps resetting to the old driver, you need to use this trick to keep the new driver
Fixed all problems!
No longer need xming and wayland integrates much nicer with windows desktop
