You shouldn't need to do anything other than install the package.

If it doesn't appear to be working, firstly I would try uninstalling the 
fglrx package, reboot, (re)install the fglrx package, reboot and look 
again. A reboot is ALWAYS required after installing/updating etc. You 
will need to (re)install the package AFTER you have sorted out the xorg 
downgrade. The reason I recommend uninstalling fglrx first, rebooting, 
then reinstalling and rebooting is that the uninstall will clean up any 
remnants of the old failed installation and the reinstall should then 
have a clean system to work on.

Running 'lsmod | grep fglrx' should show you if the module is loaded. 
Checking your xorg.conf should show the driver as fglrx, not radeon (or 
whatever the default kernel driver is called). Running glxgears and 
noting the FPS score is also a good way to confirm OpenGL 3D 
acceleration is working as expected.

Below I will provide details of what the script within the package does 
on install so you can check this has happened correctly:

1. Backup and move existing xorg.conf if it exists and recreate fresh 
xorg.conf by running 'aticonfig --initial'

2. Make sure there is a "Files" section in xorg.conf.

3. For each compatible kernel listed in /boot/grub/grub.conf, add the 
following kernel argument to disable the old radeon driver: 
'radeon.modeset=0'

4. Run 'ati-config-display enable' to enable the driver

5. Create /etc/ld.so.conf.d/ati.conf and run ldconfig


If you are unsure, please post copies of your xorg.conf and grub.conf files.
