i have a dell xps 7100 desktop with 6 gb ram, amd 5870 hd graphics card and amd phenom x6 1090t processor. I installed fedora 17 64 bit on an external usb hdd installed to the desktop yesterday. Today, i was looking for the drivers and installed the 12.6 beta catalyst release from amd's website. Now when i start the pc gnome 3 starts in fallback mode and says that my hardware is not good enough to run gnome 3. I have run gnome 3 on an intel atom at 1080p so i know that is not the case. Also the fan makes a lot of noise and the pc is running very slowly and very hot.

It's probably a kernel-version problem. You have a unsupported version of kernel. Then if you have (and I really think you have) a Kernel version>=3.4 you have to uninstall the catalyst (via the /usr/share/ati/ or aticonfig --uninstall) and reboot. Now the fallback mode should be gone. If you want to use the Catalyst I suggest you to downgrade the Linux Kernel to a lower version and install the catalyst again. I have your same videocard and Catalyst 12.6 works great with the Kernel 3.3.7-1 (with the open-drivers I had an hot GPU temperature, now it's fine), you can download it from: Don't forget that you have to download the kernel, headers, tools and devel RPM for a good Catalyst installation.

I hope this helps!
