I'm using HP Pavilion with nvidia GeForce GT 740m, after finish installing ubuntu 13.10 try to install nvidia driver 331.20 but i got black screen after login to ubuntu. how can i fix the problem ?
i solved by installing Bumblebee. add the ppa to my system from the Xorg-Edgers PPA
check which nvidia driver you already installed run this command
then install bumblebee
