Nvidia: could not open the device file /dev/nvidiactl

Hello guys,
it's some week that I noticed this error in my console, even if I didn't find so many changes or problems due to it.
Anyway I prefer not to see that error showed anymore, but I don't know hot to solve it.
It says:"could not open the device file /dev/nvidiactl (no such file or directory)",in fact I don't have /dev/nvidiactl at all!
I installed nvidia 302.17-1 and nvidia-utils-bumblebee 302.17-1.
Does somebody know how to solve it?

Give what you have. To someone, it may be better than you dare to think.

mmm I don't know what you mean with "load nvidia module".. anyway when i launch "nvidia-settings" from the terminal I receive this error: "You do not appear to be using the NVIDIA X driver.  Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server."

I typed "optirun glxgears" and it returned " /usr/bin/vglrun: line 296: exec: glxgears: not found"

Hey guys, I've just checked my Xorg.8.log and found these two warnings:
(WW): NVIDIA(0): Unable to get display device CRT-0's EDID; cannot compute DPI from CRT-0's EDID
(WW)<default pointer>: No Device specified, looking for one...
