When I open additional drivers it shows a list of propietary drivers but it won't let me change them. I click apply changes and it simply goes back to nouveau. I don't mind nouveau but it causes graphical glitches in my steam games. Steam also won't detect drivers.
I would like to install nividia driver 331 but the change instantly reverts. Is there a way I can install it manually with apt-get?
My gfx card is Geforce GT 240
