Public bug reported:
In an X session, suspend and wakeup works when initiated either by lid
close or from panel menu.
In a Wayland session, suspend and wakeup works only when initiated from panel
menu.
However, gnome-shell segfaults when suspend is initiated by lid close.
When reopening the lid, I am back at the login screen for a new session.
(When suspend-on-lid-close is disabled in Gnome Tweaks, gnome-shell and
the Wayland session survive the lid close)
In dmesg I find the gnome-shell segfault every time, here on the second
line:
