When I first installed fedora 15 everything worked perfectly out of the box, but lately I've been having problems with my graphics card driver. It doesn't seem to detect the monitor or it's native resolution, It used to; with the full model name displayed in the displays settings window, but not anymore.
So I tried a couple of things including installing the proprietary ATI catalyst driver, and It's kinda better than having an awkward resolution, but it's has performance issues, and some bugs concerning the gnome 3.
So I kept trying until I was fed up and I reinstalled a fresh copy of fedora 15.
What shocked me is that this time it had the same problem as nothing had changed and I had to install catalyst again.
What can I do to solve this?
Edit: Can this be solved by editing /etc/X11/xorg.conf?
