I have to use NVIDIA proprietary driver, open source driver does not support configuration. Darn Nvidia never released enough information about their chip's internals for open source developers to be able to write more versatile driver. I hate Nvidia for that. I love their competitor ATI: not only open source driver is way better, their proprietary drivers are consistently less buggy, and the same can be said about chips, at least I've never seen artifacts on ATI cards, I've seen artifacts on NVIDIA based cards a few times. Now, back to my boxes. NVIDIA declared these fancy cards obsolete (the are only about 6 years old, and hardware still does appropriate job for what we need). There is no proprietary NVIDIA driver which you can install with latest kernels (latest speaking CentOS 6 kernels). You know you have to compile kernel interface for their binary driver. No way: no updated binary driver for these my obsoleted by NVIDIA cards. So, NVIDIA locked me on these boxes to older kernel. So, how would you like this company after that!? </rant> Valeri ++++++++++++++++++++++++++++++++++++++++ Valeri Galtsev Sr System Administrator Department of Astronomy and Astrophysics Kavli Institute for Cosmological Physics University of Chicago Phone: 773-702-4247 ++++++++++++++++++++++++++++++++++++++++
