Default Re: could not open device file /dev/nvidiactl

make sure you have an entry in /etc/udev/rules.d/50-udev.rules for your card.

the entry will look something like this

###################/etc/udev/rules.d/50-udev.rules############

KERNEL=="nvidia*", NAME="%k", GROUP="video"

##############end of /etc/udev/rules.d/50-udev.rules ############
then make sure your user is part of the "video" group
