I am experiencing the exact same symptoms; sddm (on weston) starts
perfectly, launching a KDE wayland session freezes at various points
(leading to plenty of premature celebration), but normally on the
handoff from sddm to kde (replete with terminal cursor on screen)

Working perfectly as of the end of 6.7 final release, broken as of 6.8 rc1.
Sometimes sddm can be successfully restarted via ssh, other times
restarting sddm is slow and fails to complete.

Yours sincerely,
Donald
