after I upgraded my fedora8 to fedora9 something happened and I can not use GUI anymore, only text mode. Fedora8 worked just fine. When I come to logon screen in text mode iy obviosly tries to get into GUI (it blinks for 10 times) but nothing happens after that, only text mode is available.
Windows works fine (dual boot).
I believe something is wrong with the driver (maybe not). How can I check if driver is installed and working? How can I install it?
