I am trying to configure an old laptop, and this is driving me up the wall. I have spent at least ten hours trying solutions to no avail.
I initally installed mesa 7.11, which did not work. I currently have mesa 8 along with the Xorg Edgers mesa-legacy 7.11 drivers.
sudo lshw -c video
returns:
display UNCLAIMED

I have tried many different Xorg options, downgrades of driver packages and the like. The only two outcomes I have been able to achieve are:
NoAccel in xorg.conf: VGA driver is used, and GLXgears gets ~5 FPS. Not an optimal outcome.
Anything else: Any OpenGL application crashes on startup with the error "Wait returned -16" and the system completely locks up, necessitating power cycling.
Well, there is a third outcome that I noticed: enabling ShadowFB caused artifacts all over the screen and made the bottom half of the screen unusable.
Any help is much appreciated. I have seen that this issue has been raised before on several websites while trying to diagnose this problem, but nothing suggested has worked.
