Description Roke Julian Lockhart Beedell 2024-03-26 16:55:36 UTC

Created attachment 167800 [details]
journalctl traces and error logs from priority 1 to 3.

STEPS TO REPRODUCE
1.  Set `kcmshell6 kcm_sddm` to https://forums.opensuse.org/uploads/default/original/2X/9/90badc3f0db5d3a3f697fcd7770208133305dbb8.png — "Plasma (Wayland)".
1.  Updated to cpe:/o:opensuse:tumbleweed:20240321.
1.  Initialized computer via WOL.

OBSERVED RESULT
Automatic login failed: I saw a TTY, which waited some seconds with an underscore. Afterward, briefly saw dmesg output containing $DISPLAY initialization failure message. Switching to X in SDDM permitted login.

Investigation showed journalctl filled with `-p` 1-4 errors. For reference, no priority 1-2 errors were present in journalctl in the immediately previous boot.

EXPECTED RESULT
I should be able to login via Wayland.
