I'm installing Oracle Linux 6.1 and can't seem to get my second monitor to be recognized by the OS. I think that the issue is with the NVIDIA drivers but, after downloading and installing 3 different version of the RHEL driver I still can't get the second monitor to be recognized. Does anyone know if there are specific Oracle Enterprise Linux NVIDIA drivers available? So far, a Google search is not providing any answers.
You will need the Nvidia drivers and the kernel headers. Are you getting successful installs?
Also, realize that the way the Nvidia drivers behave, if your 2nd monitor is doing an intelligent switch/scan that the drivers may time out and not scan for the 2nd display.
Also, have you disabled the nouveau driver?
