Are you able to run glxgears with the nv (open-source) driver? It
does not work for me (x86_64 PCI-e 6600 GT):
Yes, the above slow results are with
nv (ie default installer chosen
driver / config) - there is no error, however it appears that the gears
are not being clearly updated on the screen; CPU use goes to 100% but I
think that would be normal :)
