Installed Ubuntu 15.10 beta2 on another partition to check. It's
running with 352.

The devices are created with 666 root:root:

$ ls -l /dev/nvidia*
crw-rw-rw- 1 root root 195,   0 Oct 19 00:13 /dev/nvidia0
crw-rw-rw- 1 root root 195, 255 Oct 19 00:13 /dev/nvidiactl

Let me know if you would like to check anything else.

Kind regards,
