looks like i have the same problem.........

zzehli commented 1 year ago

I have both Ubuntu 20 and 18 installed on my wsl2. Ubuntu 20 has no problem opening GUI apps, only 18 has problem. For now I am using VcXsrv to open GUIs on Ubuntu 18.

oleksis commented 1 year ago

I wrote about this issue, having the same behaviour: X server display socket is being deleted

oleksis commented 1 year ago

✅ Update the sequence of steps and resolve this issue: Init /tmp/.X11-unix is overwritten by mounts

hideyukn88 commented 1 year ago

Please update to WSL 0.70.0 by wsl --update, and check if this still occurs, we have addressed several X connection issues in this release, thanks!

oleksis commented 1 year ago

I have updated and the issue continues

PD: Make this test removing sudo mv /etc/tmpfiles.d/wslg.conf ~ from the previous solution with WSL version 0.68.2.0

hideyukn88 commented 1 year ago

@oleksis, thanks for trying out, WSL 0.70.0 contains the fix for the issue like @zzehli mentioned at https://github.com/microsoft/wslg/issues/844#issuecomment-1260271455 where multiple distros are installed, and one distro is working but other is not. But there is still some having missing X11-Unix socket issue after update to 0.70.0 like https://github.com/microsoft/wslg/issues/853, I will continue to look into such issue, thanks!

oleksis commented 1 year ago

Just update to wsl v1.0.0 from the web options and after few minutes the problem repeat. This time i fix like before. All the steps for Update to WSL v1.0.0

hideyukn88 commented 1 year ago

@oleksis, do you have systemd enabled? thanks!

imaginabit commented 1 year ago

I have the same problem with systemd enabled, All worked until update wsl, I have systemd enabled

change /mnt/wslg for /wslg , in my system /mnt/wslg exist but is empty ,

didn't solve it

oleksis commented 1 year ago

@oleksis, do you have systemd enabled? thanks!

Systemd is enable by default. I thinks I have enabled. How verify?

imaginabit commented 1 year ago

Systemd is enable by default. I thinks I have enabled. How verify?

you have to enable it on /etc/wsl.conf 

cat /etc/wsl.conf
[boot]
systemd=true
# Automatically mount Windows drive when the distribution is launched
[automount]
# Set to true will automount fixed drives (C:/ or D:/) with DrvFs under the root directory set above. Set to false means drives won't be mounted automatically, but need to be mounted manually or with fstab.
enabled = true
# Sets the directory where fixed drives will be automatically mounted. This example changes the mount location, so your C-drive would be /c, rather than the default /mnt/c.
root = /

Ok now works for me

@imaginabit, would you please check if gdm.service is running on your system by systemctl -t service | grep gdm ? thanks!

Masamune3210 commented 1 year ago

did you mean to do ll instead of ls?

AlphaScorpii-dev commented 1 year ago

I have 3 distributions installed right now (Debian / Ubuntu / openSUSE Tumbleweed). Both Debian and Ubuntu are working, the openSUSE is the one that breaks after an initial update (works after a fresh install, not after a zypper dup) For some reason, /tmp won't be populated with the entries listed in usr/lib/tmpfiles.d/x11.conf

imaginabit commented 1 year ago

@imaginabit, would you please check if gdm.service is running on your system by systemctl -t service | grep gdm ? thanks!

 systemctl -t service | grep gdm
 gdm.service                                            loaded active running GNOME Display Manager

when I stop the service with systemctl stop gdm.service and try to execute firefox ,get again

Error: cannot open display: :0

sudo systemctl disable gdm.service

and 

wsl --shutdown

and again get display error but also 

:~$ firefox

remove firefox and install it again with

snap remove firefox

# in other terminal 
snap install firefox

and now I get the same Error: cannot open display: :0 again without the other messages
