  Oh thanks! I had seen that page before but didn't look closely. Looks 
like maybe if I disable visual effects in GNOME I might be able to make 
it usable, because some of the lowest end cards on that chart should be 
comparable to the Intel IGP on the Core i5. Or maybe I don't have proper 
drivers installed. But thanks a lot, this should point me in the right
