Ignore that - that's the driver it needs. <nsip> > Clues would be appreciated. thanks in advance! Someone (Karanbir?) sent me a link to the CentOS FAQ that responded to that, but I can't seem to find it, and the "FAQ CentOS General Questions returns a totally blank page (even in view page source). I found this on a quick google: <http://www.centos.org/docs/5/html/Deployment_Guide-en-US/s1-xconfig-dualhead.html> Your other options are kmod-nvidia, or the proprietary drivers - note that in the latter case, every time you get an updated kernel, you need to rebuild (which isn't a big deal). If you go this route, you'll find a new menu item, Nvidia control panel. Enable twinview, and you'll be good. mark
