[ubuntu] How to install proper drivers for video cards

view story

http://ubuntuforums.org – Hello, peoples. I have been running Ubuntu off and on for a couple of years now (still love it), and I realized that I might not be running the proper drivers for my video card. Then, I realized that I don't even know what video card I even have. Would anyone be able to direct me to how to find my video card type, and the correct drivers? (I peeled the stickers on my laptop off because they looked tacky.) (Hardware)
