Bug#963980: Also my nvidia card is not detected.

Show all headers | View raw

I've just upgraded from nvidia 450.57-2 to 450.66-1 and observe exactly 
the same problem. In parallel, I also upgraded bumblebee from 3.2.1-25 
to 3.2.1-26. And x-server from 2:1.20.8-2 to 2:1.20.9-1. Also my nvidia 
card (NVIDIA Corporation GM206GLM [Quadro M2200 Mobile]) is now not 
detected automatically anymore. Adding it manually in the config also 
solves this problem for me.

I've experimented a bit with the involved packages and observed this:
- downgrade the nvidia-driver: still no auto-detect
- downgrade bumblebee: still no auto-detect
- downgrade the xserver: auto-detect works again
- upgrade nvidia-driver and bumblebee: auto-detect still works!
- upgrade xserver: auto-detect broken again

So I believe one can workaround this problem as well by doing:
apt install --only-upgrade xserver-common=2:1.20.8-2 
xserver-xorg-legacy=2:1.20.8-2 xserver-xorg-core=2:1.20.8-2 
xserver-xephyr=2:1.20.8-2 xwayland=2:1.20.8-2

Maybe this information helps someone to figure out what is wrong.
