CUDA Requires root?

[Kunin]

I moved one of my cards (not SLI) from 2nd slot to 3rd to increase the airflow (top card was overheating) and now need to run BOINC as root to get CUDA to work... what is going on and how do I fix it?

Ubuntu 8.10 x64 2.6.27-14-generic

CUDA 2.2 installed, 2x GTX 260

Thanks again!

Do you still have this problem?

Nope, for some reason my nvidia driver files got set to an unknown group (44), was very odd.

Add boinc to the video group.

Code: [Select]

ls -l /dev/nvidia*
crw-rw---- 1 root video 195,   0 2009-09-11 23:07 /dev/nvidia0
crw-rw---- 1 root video 195, 255 2009-09-11 23:07 /dev/nvidiactl

sudo vi /etc/group
etc...
I guess since your's is working, I'm posting this for others who might run into this.

The thing is, you don't have to and you shouldn't to. Why run boinc with root privileges? Leave it where it belongs, user land.
