Title: CUDA Requires root?
Post by: Kunin on 18 Jul 2009, 08:21:18 am: 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!

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

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.
