I recently bought a GTX 750Ti which isn’t supported by Ubuntu’s drivers yet. So I installed the drivers from Nvidia itself. They work great, the card is very quiet and operates without getting hot at all. One problem: after running an Ubuntu update that updates your kernel it won’t work anymore.
Examine the output: My nvidia driver src location: /usr/src/nvidia-334.21
If the commands fail on missing linux headers, install them:
Now you have 2 options: Reboot or do a modprobe nvidia and restart X
Enjoy fancy Nvidia graphics again
