So recently i installed Ubuntu 11.10 and first thing i always do is checking additional drivers but nothing shows there , and when i go to "System Info" > "Graphic" there is "Driver:Unknown Experience:Standard" , but experience is not even close to standard. I know that AMD have bad driver support for Linux based OS but i am experiencing some bad situations like: "blank screen" (neither unity launch bar or upper taskbar or whatever is showing up, and i can't do nothing about it, neither reset or start up system monitor.) this is very annoying to me and its causing few more problems, it sometimes seems like "Ubuntu is lagging". So if you know how to fix that stuff please tell me. Thank you.
