The proprietary driver will break the graphical boot up, and the text tends to be large due to resolution/screen size differences but that shouldn't be an issue once you hit the desktop manager.

I take it you didn't use Catalyst through the Fedora repositories, but instead obtained it directly from AMD, given you're using a Catalyst driver from November? Current in the Fedora repositories is 10.12 and the AMD website is offering 11.1 which allows the screen tearing issue to be resolved.

The cleanest way if you have to ask might just be to backup, reinstall and use it from the Fedora repositories if you want to use fglrx/Catalyst. Or not given as you note the open source drivers provide 3D for your card. Otherwise you basically need to undo the locking down of the open source drivers you were supposed to do, and then remove the Catalyst driver in the opposite of how you put it in.

su -c 'yum remove kmod-fglrx'
is probably what it should look like in command line to remove it, but as it is a graphical driver you need to be cautious about such things. Also doing this won't exactly restore things to their prior status by itself.

If you installed Catalyst from source there should be an uninstall file in the folder you downloaded

mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
cd /"Folder you downloaded for catalyst"
Should uninstall catalyst
Some other changes may be needed depending on what was changed with the catalyst install
