external monitor static image after unlocking session

[Joe Barnett]

Occasionally after unlocking a locked gnome session, the image on my external monitor is "frozen" -- it displays the unlocked desktop as of the lock/unlock time, but does not update (no mouse cursor etc). Started noticing this post-jammy release.

Unplugging and replugging the monitor fixes it. Internal laptop display does not have the issue.

Thanks for the bug report. Next time the freeze happens please:

1. Replug the monitor to fix it.

2. Wait 10 seconds.

3. Run:

   journalctl -b0 > journal.txt
   lspci -k > lspci.txt

4. Attach the resulting text files here.

Please also remove these extensions:

and then log in again. Since extensions cause such a large number of bugs, removing them is the first thing to try.
