Image rendeing problem

[Pat Kane]

I think Fedora Bug 468860 describes the same  problem
    <https://bugzilla.redhat.com/show_bug.cgi?id=468860>
    Description of problem:
    using the intel driver in my xorg.conf results in a lack of any
    OpenGL output to the screen, glxgears results in a black box
    which still spits out the number of frames drawn but unfortunately
    fails to put out any image to the screen.

the upstream Bug 18430 is at:
    <http://bugs.freedesktop.org/show_bug.cgi?id=18430>

Both reports have tweaks to try to workaround the problem.
