Cannot access GPU via SSH with unprivileged account

Hi all,

I have met a similar problem discussed here: https://devtalk.nvidia.com/default/topic/475012/?comment=3382808

I read the thread, but I did not find any useful information.

It seems OK with /dev/nv*:

crx-rx-rx- 1 root root 195 0 /dev/nvidia0
crx-rx-rx- 1 root root 195 255 /dev/nvidiactl

And I can get access to the GPU with root account. But if I run with non-root account, the GPU disappears.

Any advices?

What do You mean by ‘access the GPU with root account’ or otherwise? When I list the directory with my normal Ubuntu account I get the same listing You provided, likewise:

maciej@maciej-PC:~$ ls -la /dev/nv*
crw-rw-rw- 1 root root 195,   0 lut  8 06:21 /dev/nvidia0
crw-rw-rw- 1 root root 195, 255 lut  8 06:21 /dev/nvidiactl

Btw, I think that the answer is somehow in the question itself :)

You need rw privileges to the nv device nodes. Not rx.
