Configuring the fglrx module for ATI graphics chips in CentOS and RHEL 5

building and installing fglrx directly from amd is easy and takes 5 minutes.
The installer builds the rpm for you.

1) Download the driver from AMD.

 ati-driver-installer-8-7-x86.*.run   (ver = 8.512) -  works well.

2) Install the necessary kernel headers & devel

  yum install kernel-devel kernel-headers rpm-build

3) Install the necessary compat libraries

  yum install 'compat-libstdc++*' 'compat-glibc.*'

4) as root

4.1) to see what pkgs can be built
sh ati-driver-installer-8-7-x86.*.run --listpkg | less

4.2) to build the rpm for your distro (for me = RedHat/RHEL5)
sh ati-driver-installer-8-7-x86.*.run --buildpkg RedHat/RHEL5
4.3) install it
rpm -ivh fglrx64_7_1_0-8.512-1*

5) Assuming this was successful - configure it (as root)

  aticonfig --initial

or to see the eye-watering array of options

  aticonfig | less

Rebuild Kernel Modules after Kernelupdate

One issue with the driver is you'll have to rebuild the kernel modules after each kernel update.

Here's a script I use:


# Builds updated kernel module (based on currently loaded kernel)
# This driver was installed via RPM, built using:
# sh –buildpkg RedHat/RHEL5_64a
cd /lib/modules/fglrx/build_mod

cd /lib/modules/fglrx

echo “To complete the process you must 'init 3' and 'init 5'”
echo “lsmod | grep fglrx”
