I have a similar issue.
I installed Natty a couple of days ago. When Unity came up, it was
sluggish and many apps crashed. I switched to "classic with no effects",
and continued setting up stuff. Later I realised that hardware
acceleration was not working. I fixed it (don't remember how), and the
problems became worse.
Since my idea for this machine is to use it as a media center, I
installed many of this apps, and thought that there were buggy, as I
could only see blank screens.
Later I realised that not even glxgears works. If I disable KMS, or set
LIBGL_ALWAYS_SOFTWARE=1, they work, but so slow that the apps are
unusable.
I have already tried installing the propietary drivers, which tell me
that my card is unsupported. I installed the X edgers drivers, with no
improvement. Tried different xorg.conf tweaks that I found on the 'net,
no dice.
As most of these media apps for some reason require 3d accel (stupid
shiny effects), I need to make this work.
