I just installed Ubuntu 11.10 and I did all the software updates. When I went into Additional Drivers, I saw that my ATI/AMD Proprietary FGLRX Graphics Driver is not activated. It says (post-release updates). I tried activating it, but it does not work? Ubuntu is really slow and nothing seems smooth? Also, my laptop fan is constantly on, which makes my laptop SUPER HOT. Someone please help!
