Public bug reported:
Description:
The system was previously on 22.04, then upgraded to 23.10 to the
current daily 24.04. System will freeze up a few minutes after startup
(with no apparent related crashes). After various trial and error, the
possible cause is isolated to indicator-keyboard when running gnome-
session-flashback (freeze does not happen anymore with flashback
interface, after indicator-keyboard package is removed). Not sure why
this is not happening with vanilla gdm3. Also, the freeze was first
observed after the upgrade to 23.10.
