@c4artisan, would you please share WSL version from wsl --version on Windows command prompt and share logs from /mnt/wslg/*.log, thanks!

[sarim]

Is it somehow related to #1030 ? Google-chrome and other electron apps failed to open with error

[830:830:0411/002028.047290:ERROR:wayland_connection.cc(187)] Failed to connect to Wayland display: No such file or directory (2)

symlinking wayland-0 from /mnt/wslg/runtime-dir

ln -s /mnt/wslg/runtime-dir/wayland-0* /run/user/1000/

Now chrome and electron based apps open. Also gedit / gnome apps also open instantly.

chrome has no problems booting up for me at least

[fargiolas]

Same here, emacs (pure gtk) stopped working in wayland since this morning. The symlink trick seems to fix it.

[dvbcloader]

the symlink trick did it. now we have to wait for an official fix

[hideyukn88]

@c4artisan, thanks for info, but I do not observe this issue with the WSL version you have noted. But it's possible some of Ubuntu systemd unit might be deleting them. As a matter of fact, their gdm unit deletes X11 sockets, so WSL is monitoring that to restablish if that's happen, so it's possible that same is required for Wayland socket. Would you please share output from systemctl -t service? thanks!

Interesting thing is pipewire socket is present here. But not wayland. Ubuntu 22.04.2 LTS.

chrome has no problems booting up for me at least

I forgot to mention, I had ozone-platform=wayland etc flags set in both chrome and electron apps. By default these run on X, but I run these on wayland, that why I get error if wayland socket is not present.

[MrStillwater]

I had the same issue on Debian 11. Symlink did the trick:
WSL version: 1.2.1.0
WSLg version 1.0.51

[harleylrn]

Same issue here.
Wayland socket not created.
WSL version: 1.2.0.0
Kernel version: 5.15.90.1
WSLg version: 1.0.51
MSRDC version: 1.2.3770
Direct3D version: 1.608.2-61064218
DXCore version: 10.0.25131.1002-220531-1700.rs-onecore-base2-hyp
Windows version: 10.0.19044.2728

Ubuntu 22.04
Was working on Ubuntu 20.04 :)

Thanks for all reporting the issue, would you please try if this still occurs if systemd is disabled? thanks!

@hideyukn88 without systemd, XDG_RUNTIME_DIR is set to /mnt/wslg/runtime-dir. And wayland-0 is present in /mnt/wslg/runtime-dir as expected. GUI apps in wayland also work.

With systemd enabled XDG_RUNTIME_DIR is set to /run/user/1000/. and There is no wayland-0 in /run/user/1000/.

have no idea if the symlink thing changed anything so don't trust this log too much
i'll share a fresh log once i reboot wsl

Thanks all for sharing the info, now we understood the issue and working on the fix, thanks!
