Package: kwin-wayland Version: 4:5.23.4-1 Severity: normal X-Debbugs-Cc: schissdra...@rmm.li
I've installed plasma-workspace-wayland which install kwin-wayland which installed kwin-wayland-backend-wayland. When I tried to start up kde plasma in a wayland session, the screen got black for a few seconds, and then I was back at the login screen (sddm I guess). No error messages or easily findable logs or anything. After quite some research I've found ~/.local/share/sddm/wayland-session.log which explained me that it couldn't find any viable backend. Seems like the installed kwin-wayland-backend-wayland doesn't work. So I've just tried to install kwin-wayland-backend-drm and then the sessions was able to properly start up. Don't ask my why kwin-wayland-backend-wayland was installed instead of kwin- wayland-backend-drm. But I remember that I've tried wayland out, maybe 1-1.5 years ago, maybe there were some rest overs? But I guess for most installations the drm should be preferred. Or at least mentioned in the description of plasma-workspace-wayland? Then sddm should show a proper message, which would help a lot, and instead of only logging to ~/.local/share/sddm/wayland-session.log which is basically impossible to find, it should also log to journalctl.
