My understanding is (someone correct me if I'm wrong here) that nouveay "driver" is just a wrapper that figures out what video chipset you have and loads appropriate open source driver (nv in this case) for that chipset. <rant> And indeed, nvidia proprietary driver "will work better" for less trivial cases. E.g., if you attach two screens with different resolution. open source driver will not handle it, whereas proprietary driver will. This is why I, to the contrary to majority of Linux folks, never favored nvidia. ATI (at least before they were bought by AMD) and matrox were disclosing much more detail about their chips, thus providing to open source developers sufficient information about chip internals to write decent driver. I also am set off by many people saying "recompile nvidia driver" for new kernel. It is not the driver you are recompiling. It merely is the interface between precompiled by Nvidia binary driver and different kernel. </rant> Valeri ++++++++++++++++++++++++++++++++++++++++ Valeri Galtsev Sr System Administrator Department of Astronomy and Astrophysics Kavli Institute for Cosmological Physics University of Chicago Phone: 773-702-4247 ++++++++++++++++++++++++++++++++++++++++
