Ubuntu: Integrated Graphics not recognized on Ubuntu 15.04


I've got an Asus G751JW which has an Nvidia GTX 970M and some integrated intel graphics card as far as I know. What I'd like to do is disable the Nvidia card and just use the integrated graphics.

Mostly because I don't game on the system anyway, but also because the proprietary nvidia drivers do not work properly. I get graphics errors constantly which mess up the login screen so I cannot log in anymore at times. Also I can't change the display's brightness no matter which driver I use for the Nvidia card (and I have tried lots of things to fix this to no avail) ...

Anyway, so I heard you can switch to intel using prime-select. Nope. I can't since the intel card is not recognized.

I also heard you can disable the Nvidia card using bbswitch. Nope, cause the intel card is not recognized.

Any idea why the integrated card is not recognized?

additional drivers

Output of lspci -k | grep -EA2 'VGA|3D':

You need to install Nvidia proprietary drivers to use nvidia-prime. Run in terminal

sudo apt-get install nvidia-346 nvidia-prime  

and reboot.

You will be able no switch adapters in Nvidia X Server Settings and by prime-select command.

If the 346 driver does not work well, you can install 352 by

sudo apt-get purge nvidia*  sudo killall nvidia-persistenced  sudo add-apt-repository ppa:xorg-edgers/ppa  sudo apt-get update  sudo apt-get install nvidia-352 nvidia-prime  sudo add-apt-repository -r ppa:xorg-edgers/ppa
