Comment 3 for bug 1158611

@Robert: this is not really a Unity problem. The user is trying to use fglrx/Catalyst and it is not installed properly, so there's no 3D acceleration available. Normally, Unity falls back to software 3D (llvmpipe) in such a case, but llvmpipe (or any open-source 3D driver) will not work correctly if a proprietary video driver is installed.
