[kde-unstable] sddm doesn't start setting QT_WAYLAND_SHELL_INTEGRATION

Hi,

sddm seems to be broken when using the Wayland configuration present on the Wayland section of the wiki (https://wiki.archlinux.org/title/SDDM#Wayland):

[General]
DisplayServer=wayland
GreeterEnvironment=QT_WAYLAND_SHELL_INTEGRATION=layer-shell


[Wayland]
CompositorCommand=kwin_wayland --drm --no-lockscreen --no-global-shortcuts --locale1

Setting the config to just:

[General]
DisplayServer=wayland

Makes it work.

Found the solution while browsing https://bugs.kde.org/show_bug.cgi?id=498861, so I'll copy my answer there here:

I was also been affected by this. From the open MR, look like it's an issue caused by lack of permissions to access an set icc profile.

Removing the icc profile from /var/lib/sddm/.config/kwinoutputconfig.json fixed it.
However, I guess it makes wonder if either the icc profile should be copied to the sddm folder or if it makes any sense to set the it at all.

If you are having this issue, try removing any

                "iccProfilePath": "",

Entries you might have in /var/lib/sddm/.config/kwinoutputconfig.json
