Thanks for the reply.
I actually didnt install any drivers--Im just using the default packages that came with the fedora 10 complete install disc. This includes the full xorg driver package and the mesa dri drivers (are these the same thing?).
As for the output of, lspci | grep VGA, it seems that util isnt available on my system and it doesnt show up in any of my rpm repositories. Is it a non-standard alias for something else? For what it's worth, the output from lsmod says my driver is the i915.
Ive also tried generating an xorg.conf instead of using the default probed one--it didnt make any difference as far as I could tell, but I also didnt try changing any parameters. Im not really sure what I would try--perhaps I should try using the i810 driver? (it's older and possibly more stable?)
Im thinking there might just be a problem with this i915 driver. When I try to run the standard version Blender3d (3d modeling app), it is horrendously slow, the lighting is completely messed up, and the menus dont display properly. However, when I use the non-hardware-accelerated version, it works somewhat slowly, but without any bugs.
