Public bug reported:
This is a Hybrid graphics laptop with Ubuntu 22.10 and xserver-xorg-
video-nouveau version 1.0.17-2build1.
After locking the screen manually or automatically after the specified
timeout, the whole laptop freeze or behave extremely slow, either ways a
hard reset is a must by holding the power button to bring it back to
life.
This doesn't happen if the nvidia proprietary driver is used.
Right after a fresh boot, you can see the nouveau error in the attached
dmesg.txt file.
Sometimes while trying to unlock or switching to tty it shows such
errors:
