I have a Dell Latitude E6500 with Ubuntu 12.04 LTS and after a fresh reinstall, I notice some sluggishness, which is probably due to the video drivers. My graphics card is a NVIDIA Quadro NVS 160M. When I open Additional Drivers, there are various options but I don't know which is the best one. Many thanks.
This is what I get with
sudo lshw -c video
