How to turn off nvidia (hybrid graphics)

Solution 1:

Thank you for the hint with the proprietary driver. It saved my kubuntu experience. With nvidia version 340 it works perfectly. Furthermore I figured out there was no option in nvidia x server settings menu to switch between the two shown after installing, but you can do it via terminal:

with prime-select query you can see, which one is currently running.

with sudo prime-select intel you can turn on the intel card.

with sudo prime-select nvidia the other one.

Solution 2:

I've been struggling repeatedly on my Asus N55S with an NVidia GT 635M. Especially after the upgrade to Ubuntu 14.04. NVidia is just so evil with the Linux community and its drivers are a well known pain in the neck... Here is what I did:

sudo apt-get install bbswitch-dkms

then

gksudo gedit /etc/modprobe.d/blacklist.conf

and add the following lines

# Blacklist the alternative nvidia module 
blacklist nouveau
# Blacklist the original nvidia module 
blacklist nvidia

then

$ gksudo gedit /etc/modules

and add the following lines

# Switch off discrete GPU 
bbswitch load_state=0

at last update the initial ramdisk by running

$ sudo update-initramfs -u

Solution 3:

There should be such an option in the bios.

Otherwise you can install the proprietary driver and under the nvidia control panel you can select which chipset you want to use. Select the Intel one.
