When I had XP, after installing it, I used to run the setup.exe file for graphic driver. This used to greatly improve graphic quality, like good looking small icons, cleaner videos, and so on. Now, for Ubuntu too, there must be a similar graphic driver, maybe provided by intel, (a counterpart of "setup.exe" for ubuntu), which would improve graphic quality just like in windows. Trouble was I could never find one. Need help.
BTW in xp I needed sound driver too, to enable sound. I don't need anything for Ubuntu.
