[mythtv] Xorg CVS screw up OpenGL

[Paul Webster]

Hi Pedro,

Did you install the Mesa OpenGL libraries from dri.freedesktop.org?

I'm running the same hardware and have been through the process of
recompiling X (4.4.0, had too many problems with the bleeding edge
version) to use unichrome. I haven't tried the MythGallery OpenGL
transitions, but running glxgears seems to be much nicer than it was
before for me (will test Gallery tonight when I get home).

I basically followed the howto from unichrome.sourceforge.net for X,
and then downloaded and compiled the drm modules and Mesa libraries
from dri.freedesktop.org (also with detailed build/install
instructions)
