The important thing to check is the xorg.conf. You will see some mode lines. If you manually edit the same mode lines from the Fedora system into the CentOS one, it should work identically, barring any bugs in the underlying drivers. There is other information that might also be applicable, monitor, etc. That should also work if you apply those types of things. There may be some differences in the drivers that may or may not be significant. I don't recall the CentOS drivers version (rpm -q <whatever> will tell you), but if it looks unsuitable, there's also some on rpmforge that support both some of the newer and also drivers for some of the older Nvidia cards. I've been using the rpm for the older one for some time. Also, there's been some recent traffic on the mailing list about the kmod (IIRC) instatiated version of some of the nvidia drivers. Using a google advanced search for site centos with all the words nvidia, kmod and video should get you some more info if you end up needing it. BTW, I'm a tyro at this stuff, so if I've mentioned any FUD, hopefully one of the more knowledgeable folks will jump in and correct me. > HTH -- Bill
