Thanks for the bug report. When the second monitor is plugged in, please
run:
sudo apt install drm-info
drm_info > drminfo.txt
grep . /sys/class/drm/*/status > connections.txt
journalctl -b0 > journal.txt
and attach the resulting text file here.
Please also clarify if you are using a native USB-C monitor or a
DisplayLink adapter.

Title:
Second screen over usb-c stopped working after update
Status in linux-hwe-5.19 package in Ubuntu:
Incomplete
Bug description:
Hello,
I recently got an update on my system which wrecked havoc on my
display drivers. I cannot use a second monitor now any more through
usb-c. When I plug in the screen nothing happens. I have verified
whether there is any hardware failure (screen, cable, usb-c converter,
usb-c ports on the laptop) and they all seem to be fine.
I suspect it's this update which caused it:

Could you please have a look and let me know if there is any
workaround. This sets me back hours in investigation time...
