Public bug reported:
After I wiped down my laptop's touchscreen with a wipe, GNOME went to
the "Activities" screen (I must've hit the button while wiping down the
screen), then GNOME became unresponsive.
By unresponsive, I don't mean it froze. The mouse cursor still moved
smoothly. It even recognized touch events by hiding the cursor when I
tapped the screen. But it ignored literally everything else. The one
other thing that changed the UI was changing my keyboard's backlight,
which caused a volume-esque dialog to show up notifying me of the
change, before quickly fading. I couldn't even use the Fn-Ctrl-Alt-X
keys to switch to a TTY.
I then closed my laptop's lid to put it to sleep and reopened it a
little while later. The lockscreen was perfectly functional, but once I
logged back in, the problem remained. Although Fn-Ctrl-Alt-X keys worked
again.
At that point I gave up and restarted my laptop. It's a good thing I
didn't have anything important unsaved, or I could've just lost my data
because I wiped down my touchscreen.
I'm using Ubuntu 22.04 Wayland, GNOME Shell 42.2 (according to gnome-
shell --version).
