Hi, I'm having what seems to be GPU hangs (they occurred consistently
using both Openbox and IceWM, with both Firefox and Epiphany, and
always when playing video, both with videocall or YT videos), screen
gets mostly frozen (but all system and software keeps responding
normally to the keyboard), Openbox eventually terminate itself and
with IceWM I can do Ctrl+Alt+F1 and `killall -s SIGINT icewm` which
produces the same result: get me back to the display manager
logging-in screen.
I'll put the info I have until now below, but the urgent ask for help
refers to the situation that I should use this laptop to work with
videocall tomorrow, so: is there any way to avoid this hangs in a
quick/temporal fashion? (Maybe installing a previous kernel, using
another driver, ..., I don't know.)
Any help would be obviously greatly appreciated.
The laptop is a ThinkPad X220 Tablet with up-to-date Debian testing.

I will follow those instructions (bug-filling) ASAP, but meanwhile I
need to keep working with the laptop...
Thanks a lot for any help or recommendation.
Kind regards.
