failed to open DRM: Operation not permitted (on fglrx and ubuntu feisty)

[After installing fglrx with apt-get install apt-get install xorg-driver-fglrx and replacing nvidia with fglrx in driver section i still had no 3d enabled and my user wasn't allowed to access /dev/dri . So i did an little search on google and got this ]
Then you are trying to run as a user that doesn't have permission to use the DRI (root is the default allowed user). To let all users access the DRI, add the following section to your xorg.conf:
Section "DRI"
    Mode 0666
EndSection
