Hello, I just want to point out that the gnome session needs to be customized to support the requirements of fglrx.
For more infos please refer to this thread: http://unix.stackexchange.com/questions/222000/how-to-install-amd-catalyst-15-7-fglrx-15-20-1046-on-debian-8-jessie Fglrx seems to only support GLX and gnome uses EGL by default. Please try this workaround. On my maschine the newest sid version (15.12) works like a charm. Regards Pascal Maximilian Bremer
