I'm trying to install my nvidia geforce 555m graphics card drivers but when i run the .run file it tells me to disable all x server windows. I googled a bit but didn't find answers. I'm running unity by the way thanks in advance.
I would not recommend to use nvidias own installer because what happens then is outside of ubuntu's package management. Just install using a terminal
sudo apt-get install nvidia-current nvidia-settings
In case you need the absolute latest drivers use the x-swat-PPA:
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current nvidia-settings
