Public bug reported: When I came back to my computer, it was unresponsive to keyboard/mouse input and the display was frozen. Upon rebooting, I found the following error in the previous boot's log:

Unfortunately, Xorg.log had already been rotated, so I was not able to capture the issue from Xorg's side. I have attached apport output from a successful boot. I am using Ubuntu 20.04.06 with xserver-xorg-video-nouveau 1:1.0.16-1 and linux-image-5.4.0-146-generic version 5.4.0-164.163. My graphics card is an "NVIDIA Corporation GK107GL [Quadro K2000]".
