Public bug reported:
After upgrading from 5.0.0.8-generic to 5.0.0.11-generic, the nvidia
card suddenly became "disabled". I own a laptop with hybrid GPU stack,
intel + nvidia; nvidia is in charge of display ports. On 5.0.0.8-generic
I had only nvidia GPU enabled (discrete mode) and nouveau was able to
properly control nvidia and send the signal to my monitor. In hybrid
mode this worked as well properly.
On 5.0.0.11-generic in discrete mode, linux booted to 640x480 resolution
only. When I enabled hybrid mode back, the computer boots into 1920x1200
mode properly, however the display port ports don't work at all, and the
"About" screen only lists the Intel GPU, not nvidia. lspci still lists
nvidia though.
