Public bug reported:

I recently upgraded my NVidia drivers on my ThinkPad P1 Gen 3.

If I start Ubuntu on Wayland session and plug in my USB-C monitor the
system reliably completely freeze. The freeze is also reproducible if
the screen is plugged in during startup and trying to login into a
Wayland session.

Only Wayland session experiences a crash. The crash happens ONLY if the
USB-C monitor is plugged in.

USB-C monitor is also a USB3 hub.


Hardware seems to work fine, as Windows shows no issues with the setup.
