Bug#900248: Direct Render problem

[Dean Loros]

Yes---the change in xorg caused the problem. I linked the nvidia  libglx.so
from
/usr/lib/xorg/modules/linux/ to /usr/lib/xorg/modules/extensions/ (renamed
the libglx.so in /extensions to libglx.so.bak). Restarted my system & now
have direct rendering.

That is a "temporary" fix that works.
