Public bug reported:

Ever since installing (not upgrading) Ubuntu-22.04, I've noticed that
quite often (but not always) unlocking the screensaver freezes the
entire system. By that I mean I will tap my keyboard, the blank screen
will lighten up and show the password field, I start typing, get the
"***" characters, and then it freezes: typing doesn't continue, mouse
stops moving. If I wait, 30-40 (ish) seconds later it will catch up and
start responding again and I can continue. Quite often the freeze
doesn't occur until I have entered my password and hit ENTER - but it
does freeze earlier too.

I have figured out that if this happens, I can speed up the process by
hitting Ctrl-Alt-F3 to go to a tty, then immediately Alt-F2 to go back
to gnome - and that flushes out the problem. Definitely shaves many
seconds off waiting around for the fault to clear by itself. I was also
talking to a collegue who installed Ubuntu-22.04 this week - he's
noticed the same issue. Also a Dell laptop - but different model.

I would guess Wayland related  - but don't have any evidence for that,
so I put this as gnome-shell

Thanks!
