Comment 6 for bug 545257

In every one of these bugs, fglrx is not being used but it is installed. To fix this you should deactivate the driver, delete /etc/X11/xorg.conf and reactivate fglrx through jockey and then reboot if you indeed have a card supported by fglrx. The reboot is required before 3D support is available like the message says when you activate it. Like Felix said, if you have fglrx installed you cannot use the open source drivers without getting this error because it overrides some X libs. This is not a bug in the package but a misconfiguration for various reasons so I am closing this bug.
