Installing latest Nvidia drivers on Ubuntu Karmic 09:20

At the time of this writing, latest version of Nvidia drivers is 195.35.15 and Ubuntu Karmic (9.10) latest Nvidia driver is 185.

So in order to update to the latest we need to add a PPA repository:

sudo add-apt-repository ppa:nvidia-vdpau/ppa

Update the repository information:

sudo apt-get update

Next, and before installing latest drivers, we will need to deactivate current 185 drivers (if activated) and we will need to uninstall them because of a conflict with newest drivers.

Deactivate current drivers in:

System -> Administration -> Hardware Drivers

After deactivating remove current drivers (185):

sudo apt-get remove nvidia-glx-185 nvidia-185-modaliases nvidia-185-libvdpau

Lastly, install latest 195 drivers:

sudo apt-get install nvidia-glx-195 nvidia-195-modaliases

Don't forget to update your packages and nvidia-settings with it:

sudo apt-get upgrade
