I think you need to be present in the video group.
Clearly the problem is because access is denied to your video card.
Just ls -l /dev/nvidiactl (you should see group video there) and add
yourself to the group.
gpasswd -a <your username> video
If the group is something else as the ls -l reveals, add yourself to
that group (unless it's root or wheel). If the group is root or wheel,
you need to modify udev/mdev rules which I'm not aware of much.
