Nouveau on Debian Buster

ā€¢

This is a brief note that is probably of no interest unless you arrived here via a search engine.

After installing Debian Buster on my Gigabyte Aero laptop I was getting hangs whenever I tried to start X, which tended to be followed by CPU soft lockups:

nouveau [...] Refused to change power state, currently in D3
nouveau [...] Refused to change power state, currently in D3
nouveau [...] Refused to change power state, currently in D3

Booting through the advanced/recovery mode in GRUB got me further, but it was still freezing regularly.

I was aiming to install the non-free nvidia-driver package. I was also installing nvidia-detect and it was triggering the above behaviour, where the entire system froze.

I found the solution in this comment on GitHub. Adding nouveau.runpm=0 as a kernel option let me actually get in and install the correct driver without any hangs. (I think it was second line from the bottom in the GRUB config after pressing ā€œeā€.)

After that driver fully installed, my GTX1060 is happy and I am running KDE as I intended.
