display is freezing randomly

[Hermann Gregor]

My display is freezing randomly, while the system seems to be running, since music is playing.

When the problem is happening please:

1. Tell us if running 'top' in a Terminal reports any high CPU usage.

2. Run:

   journalctl -b0 > journal.txt

   and attach the resulting text file here.

3. Run 'gnome-shell-extension-prefs' and tell us if disabling any/all of them avoids the problem.

[Daniel van Vugt (vanvugt)]

Please also try selecting 'Ubuntu on Wayland' from the login screen and tell us if that avoids the problem.

Dear Daniel,

thank you for your assistance, unfortunately I cannot run anything when the display freezes. The system seems to run, since sound is playing, but the display does not update at all. I have to make a hard reset by pushing the power button for a while to get the system running again.
However, it did not happen for a while now. I try to keep my system up to date, so maybe a kernel patch has fixed the issue. I will let you know if it happens again and try to disable shell extensions then.

Best Regards,
Gregor
