How do get rid of the lag when dragging windows, resizing windows and opening/closing Activities? Overall things are somewhat slow.
I am running Ubuntu 12.04 with Gnome-shell (problem remains with Unity also). I have Geforce 9300M GS graphics card and Intel Core 2 Duo E8400 processor. I have tried all the different drivers from "Additional Drivers" and even manually downloaded and installed driver from nvidia.com, but the lag remains.
