my desktop PC using ati radeon hd 4350, when i installed ubuntu 11.04 and running application for checking and install propertary VGA driver (
jockey-gtk) then my 11.04 screen resolution, activating desktop effect compiz,etc works well.
but the problems comes after i upgraded ubuntu from 11.04 to 11.10 , i can't login to my account but works by using guest account. and my 11.10 not detecting ati radeon hd 4350 although i reinstall then reactivated the propertary driver.
Thanks for any suggestion and help.
