Fedora 14 Installation Guide
This was so helpful and easy! Do you have any artliecs on rehab?
Offical AMD Driver
Note: This procedure is untested.
Preinstall required packages
The script from AMD builds a kernel module, so we're going to need to install some development packages.
su - yum install kernel-devel gcc
If you're on 64-bit you may also have to install this package too. (you do for 64-bit nVidia drivers so I had it installed anyway)
su -c yum install glibc-devel
Download the appropriate driver from http://support.amd.com/
It will be called something like ati-driver-installer-version.run.
Run the file as root in the "sh" shell.
su - chmod +x ati-driver-installer-version.run sh ./ati-driver-installer-version.run
Generate a new xorg.conf
This should do fine for most people.
su - aticonfig --initial -f
If you have multiple monitors or X2 cards then you'll need to do some other stuff, check one of the Ubuntu guides for the correct syntax.
GRUB boot config
Ensure there's a radeon.modeset=0 entry on the end of your kernel line in /boot/grub/menu.lst file, you could also use nomodeset here.
I expect the AMD install script will do this for you.
