Public bug reported:

may be it's x-org, may as well be kernel/nvidia. It happened after
switch from usb-c display port to the laptop screen. Not directly, but
after a video call. My device has 4k touch screen.

Screen went non-responding and after login on tty3 (ctrl-alt-F3) I was
able to reboot the system, but the system didn´t shut down correctly.

while shutting down I saw BUG: kernel NULL pointer dereference, address
(lots of zero's...)008c0

Connecting to and from DPlink dock normally works okay. Most
programs/windows work as expected, except nautilus. I always need to
kill and restart that program.

Hope this helps, if more info is needed: no problem.

BTW: BIOS is set to hybrid mode
