AMD Catalyst
Fglrx, or AMD Catalyst, is both more efficient and faster than the open source gallium driver, although the source code is closed, so the Linux developers can not edit the source code to fix a bug, for example.
It is not included in Fedora because it is proprietary, copyrighted software, and therefore does not adhere to F/LOSS standards.
Getting AMD Catalyst
Preperations
Upgrade your system
# yum upgrade
# shutdown -r now
Download and install the rpmfusion repositories (according to your Fedora version):
- Fedora 18
- Fedora 17
- Fedora 16
- If your browser has downloaded these packages, as opposed to requesting to open the Fedora package installer, you may install them using the following command:
# yum install /path/to/package(s).rpm
Installing AMD Catalyst
Install the Catalyst driver and libraries
# yum install xorg-x11-drv-catalyst xorg-x11-drv-catalyst-libs
Install akmod for Catalyst
# yum install akmod-catalyst
Finishing touches
Blacklist old radeon modules
# echo "blacklist radeon" >> /etc/modprobe.d/blacklist.conf
# echo "blacklist radeonhd" >> /etc/modprobe.d/blacklist.conf
Remove the old radeon driver from initramfs
# mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-radeon.img
# dracut /boot/initramfs-$(uname -r).img $(uname -r)
Reboot
# shutdown -r now
