Public bug reported:
My setup is composed of a Dell XPS13 9320, with one (or two) external
USB-C monitors attached. The laptop panel is the primary screen. I'm
using gnome on Wayland.
Everything is working fine, except when resuming from screensaver: the
prompt for password is shown on the laptop panel, and I start typing the
password. At this point, the laptop panel freezes. This can happen
almost immediately (I will see for example two or three dots as I typed
the first characters of my password) or this can happen a few seconds
later (meanwhile the screen has been unlocked, the panel shows the
desktop, then it freezes).
Interestingly, the external monitors are woken up, desktop is unlocked,
and will continue working, while the laptop panel is frozen.
After that, let's say 40% of the time, the panel will un-freeze itself
after 30 seconds or so. 40% of the time it will remain frozen, and 20%
of the time the whole display will freeze (including the external
monitors).
When it happens, I can recover by either un-plugging / re-plugging one
of the external monitors, or by typing Ctrl-Alt-F1, then retyping my
password, then everything is fine again... until the next screen lock.
This bug is reproducible more or less 50% of the time (one in two screen
locks causes freezes). Deactivating the dash-to-panel gnome extension
made it less reproducible, but it still happens.
I didn't see any interesting error message in the logs, but maybe I
didn't look at the correct place.
