Public bug reported:

I have made an update as follows:
https://linuxmint-user-guide.readthedocs.io/en/latest/upgrade-to-mint-22.html

So far it has worked, but now no external monitors are recognized,
whether via HDMI or USB-C. Before the update it worked without any
problems.

In the Display app, I don't see any other monitors apart from the laptop
screen. I have already restarted several times.

Ubuntu 6.8.0-39.39-generic 6.8.8

No LSB modules are available.
Description:    Linux Mint 22
Release:        22
