I had installed the xorg-driver-fglrx (ATI’s fglrx driver) through Apt in my Kubuntu Feisty box and it was working fine after reconfiguring using dpkg-reconfigure xserver-xorg and without installing the linux-restricted-modules. It showed the right string when I entered fglrxinfo, but the recent update to the xserver (either the update released y’day or within the last couple of days) screwed up the ATI driver. I didn’t realize that until I played some videos. When I checked, fglrxinfo showed Mesa as the driver string.
I then tried reconfiguring the xserver using dpkg-reconfigure xserver-xorg several times. The configuration showed fglrx as the driver and the xorg.conf also had fglrx as the driver, but still fglrxinfo showed Mesa. I then fixed the problem using the commands below in the order it’s written.
I opened a terminal. I then installed the Linux restricted modules.
sudo apt-get install linux-restricted-modules-$(uname -r)
sudo depmod -a
sudo aticonfig –initial (there should be two hyphens before initial, wordpress removes one while displaying)
The above command said it didn’t have to change anything since the xorg.conf file already had the fglrx string.
sudo aticonfig –overlay-type=Xv (there should be two hyphens before overlay, wordpress removes one while displaying)
Once I issued the commands as stated above, I rebooted the system. I then typed fglrxinfo in the terminal after the reboot and it showed the ATI driver as the string instead of Mesa. The videos also worked fine.
