Description Kriton Kyrimis 2024-03-29 09:02:28 UTC 
When trying to run an X11 application from a Wayland session, I get an error message about being unable to open the display. E.g.,:

$ xterm
xterm: Xt error: Can't open display: wayland-0

Looking into it, it appears that the DISPLAY variable has the value "wayland-0" (same as WAYLAND_DISPLAY) instead of ":1".

If I set DISPLAY to ":1", X11 applications run fine if started from the shell, but, obviously, not from the desktop.

The problem appears with both Plasma and Gnome, so it doesn't appear to be a problem with a specific desktop.

I tried switching from sddm to gdm, and the problem persisted, so it is not a problem with the display manager, either.

I asked a friend, who is running Debian 12 with KDE 5.27.5, and on his environment DISPLAY is ":1", so this appears to be a configuration issue with Tumbleweed.

I am running the nouveau driver on a GeForce GT 730 graphics card.

Currently testing with Tumbleweed 20240327.

Hi Kriton, would you please help to confirm whether the issue is fixed or not please? Thanks.

Confirmed.

I've been a happy Wayland user since 20240410.
