I have a laptop with Intel HD and Nvidia GPU video cards and I have a problem with installing drivers for the second. They mess everything up. Unity don't want to start, because
GLX MISSING ON DISPLAY 0:0 and resolution of screen is 640x480, though, I can't change it in terminal.
xrandr -s 1920x1080
says this kind of mode doesn't exist.
I looked up this problem and it's due to Nvidia drivers (I tried to install 310.14, but it doesn't work with other versions neither), so I want Ubuntu to see only my Nvidia card and forget about Intel one.
How do I do it?
