Nvidia drivers and kernel module 'nvidia_uvm.ko'

Postby samiel » 2020-12-15 20:27

I tried to install Nvidia proprietary drivers on Sid with Cinnamon.
Now, compared to the past, now I get the warning:
Code: Select all
Unable to load the kernel module 'nvidia_uvm.ko'
.
Therefore I have to install those drivers with the
Code: Select all
--no-unified-memory
option.
What do I have to fix / modify / install to get the module in question?
In the alternative, what does the
Code: Select all
--no-unified-memory
option mean?
Thank you

What kernel and nvidia driver versions are you using? There was a major change in kernel 5.9 which prevented nvidia_uvm loading and required Nvidia to rewrite some of their driver. IIRC the nvidia 455.xx driver is the first to have fixed this.

nvidia-driver 455.45.01-1 is currently in experimental. Either wait for it to be moved to sid or temporarily enable the experimental repo, install it, and then disable the repo.
Installing from experimental can be like playing Russian roulette; mostly it will go ok but occasionally you get a bullet in the head. :mrgreen: I've heard a couple of reports of successfully installing this driver version in sid but YMMV.
