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
sudo apt-add-repository ppa:xorg-edgers/ppa sudo apt-get update
check which nvidia driver you already installed run this command
dpkg -l | grep -i nvidia and remove it in my case i had nvidia-current .
sudo apt-get remove nvidia-current nvidia-settings
then install bumblebee
sudo apt-get install bumblebee-nvidia nvidia-319
