I was just handed a 2nd monitor for my system at work, and using Centos 5 (latest) can't make dual head work. a good bit of googling isn't being particularly helpful either.
It's a HP workstation xw4100, with Nvidia Quadro NVS280SD graphics card. Enabling dual head in the "display" app simply configures X so that it (i.e., X) won't start. I haven't found the x log file in /var/log to be helpful, either. This is using the legacy 96.x.x driver from Nvidia.
Nope, that won't work.
the NvidiaDetect app (from epel) says it should be using a newer driver than the 96.x.x (forgot which one, exactly) but when attempting to install it I get a msg that the card requires a 96.x.x driver.
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.
