Public bug reported:
I'm using basic Ubuntu 20.04 and GUI (gnome?) freezes totally.
- I was running Firefox 78.0.2 and watching Youtube. The video and sound
stopped.
- Keyboard was unresponsive, can't get into console, and for example pressing
caps lock/num lock didn't toggle keyboard leds.
- mouse didn't move.
- The whole computer and OS didn't crash I suppose. I could ping the computer
from another computer. and there were entries in /var/log/syslog after the GUI
freeze.
What ever happened I can find some indicating in /var/log/syslog:
Crash happened 14:21 local time which pinpoints the bug into these
entries:

after that anything GUI, keyboard or mouse related was totally unresponsive.
there were other entries in syslog after that, and ping worked into this
frozen machine. So the whole OS didn't crash. Only GUI related.
I hope this helps.

I'm sure this is a bug. The same effect has happened 3 times in 30 days. I
didn't check the previous syslog which error message there was.
