I'm new to ubuntu and i've been having this question since the day i installed Ubuntu. Does ubuntu come along with the necessary drivers for my Nvidia 640M graphic card? Also , My computer was overheating a few months back and i found out that the problem was with the Nvidia Optimus thing so i had to use Bumblebee and disable the graphic card. So, everytime i need to use my gc, i type $ optirun applicationname and that enables my gc again . So, do i need to install my Nvidia drivers for my graphic card and if yes, how ? Any help is appreciated. thanks in advance ! :)
Install Driver packages for Video Card :
sudo apt-get install linux-headers-generic xserver-xorg-video-all libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
If not resolved reconfigure the drivers:
sudo dpkg-reconfigure -phigh xserver-xorg
I had endless problems with the nvidia drivers that are available from ubuntu.
My problem was sorted when i with adding the follwoing repository's
for nvidia drivers;
sudo add-apt-repository ppa:xorg-edgers/ppa
sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
Then install the nvidia-319 nvidia divers and bumblebee (these will bring in the latest nvidia drivers required)
sudo apt-get install bumblebee bumblebee-nvidia nvidia-319 nvidia-settings-319 virtualgl
Reboot and should be working.
