I'll test this this week!

I the meantime - could anyone help me out with removing fglrx first? I went roughly like this:
su -c 'yum remove akmod-catalyst-legacy-* xorg-x11-drv-catalyst-legacy* xorg-x11-drv-catalyst-legacy-libs'

sudo rm /etc/X11/xorg.conf

un-blacklist xorg in /etc/yum.conf (which was used to prevent xorg from updating to keep it downgraded)


su -c 'yum clean all'

yum reinstall mesa-libGL
yum reinstall mesa-*

yum reinstall xorg-x11-server* && yum install xorg-x11-drv-intel*

I also tried updating the intel driver using their official installer.

AMD provides a script for fglrx uninstallation (.sh). Can anyone find and upload such script for catalyst 13.1 legacy so that we could all see what it actually does?
