[Pkg-fglrx-devel] Bug#767673: fglrx-driver: gnome-session fails to start. Major opcode 141 (RANDR) Minor opcode 13 (RRChangeOutputProperty).

Hello,
I think the problem is in clutter package: when gnome-shell starts, it
load the cogl library in order to manage the screen. This library
include a few drivers and select the best one based on some heuristic
(based on the GL engine found).

When running fglrx, the cogl library uses the GLES2 driver. This driver
start checking the GL engine and stop when testing the
RRChangeOutputProperty.

If you want to easily reproduce the problem, just start X11 (I use an
xfce4 desktop) and then execute this command in an xterm:

env COGL_DEBUG=all COGL_DRIVER=gles2 LIBGL_DEBUG=verbose \
 MESA_DEBUG=1 gnome-shell --replace

This will try to start gnome-shell and then fail. Its output is:

giuseppe at uefi:~$ env COGL_DEBUG=all COGL_DRIVER=gles2 LIBGL_DEBUG=verbose MESA_DEBUG=1 gnome-shell --replace
