[SOLVED] Gimp not working under Wayland/sway?

Hi all,

the excerpt below pretty much sums up my problem. Does gimp really not run under wayland? Of course it does. A search for +gimp +wayland limited to the past year turns up literally nothing. I have xorg-xwayland installed, but that of course doesn't set a DISPLAY variable (if that's the problem).

~$ env | grep WAYLAND
WAYLAND_DISPLAY=wayland-1
~$ gimp --version    
GNU Image Manipulation Program version 2.10.38
~$ gimp              
Cannot open display: 
~$

Re: [SOLVED] Gimp not working under Wayland/sway?

You have to have a DISPLAY variable set and sway should do that normally, did you disable it loading xwayland? https://wiki.archlinux.org/title/Sway#Xwayland  -- also the current version of gimp is still based on gtk2 which long predates any Wayland considerations

How exactly are you starting sway? and/or starting the terminal in which you're trying to launch gimp right now?

FWIW no issue here on KDE

consider using gimp 3 instead (not released yet but in release candidate phase)

Sway is started from my .zprofile, and xwayland is not disabled in the config::

~$ grep xwayland .config/sway/config
 
~$ cat .zprofile
if [[ -z "$TMUX" && -z "$WAYLAND_DISPLAY" && "$XDG_VTNR" = "1" ]]; then
    exec /usr/bin/sway
fi
~$

Mhm, how does your sway config look like? Did you see the note in https://wiki.archlinux.org/title/Sway#Configuration to ensure some necessary default configs are parsed? Also

ps -ef | grep -i xwayland

Stupid me. I was 100% certain that I had installed xorg-xwayland. Alas, I hadn't. Sorry for wasting your time ;-)
