I have googled & read all I could find, with no apparent solution in sight. I have a Dell desktop with a Radeon HD 5670 video card : lspci|grep VGA 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Redwood XT [Radeon HD 5670/5690/5730]
I installed the amd catalyst via the file: amd-catalyst-13.12-linux-x86.x86_64.run.
Catalyst driver mostly does not support Fedora, and more often than not it just doesn't work. Uninstall it, and use the default open-source radeon driver (see below).
my xorg.conf file shows this: ection "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx"
You want the Driver option to be "radeon". Or better yet, rename/remove your xorg.conf file and let X configure itself automatically.
<rant> ATI is known to have a notoriously lousy support for Linux in general and Fedora in particular. For their low-end and oldish cards, they provide specs on which the Linux community has built the open-source radeon driver (which works well). For their high-end cards, they refuse to provide specs (so no open-source driver), while their closed-source catalyst (fglrx) driver is a miserable POS that is almost never up-to-date with the latest kernel and X.
In contrast, nVidia does not give away the specs for their cards, but their closed-source driver simply Just Works(tm). Also, recently nVidia folks decided to provide some (limited) specs to the open-source nouveau devs, so there seems to be some light at the end of that tunnel... ;-) </rant>
IOW, forget catalyst and use the radeon driver. And if radeon driver doesn't work for your card, you are out of luck.
HTH, :-) Marko
