Compiled disper from rpm (rpm2tgz) and, after reboot with secondary display connected and on, no cigar:

No secondary display found, falling back to primary.

lspci is to list pci bus devices.

If you add -vv (that is two v's) as a switch (lspci -vv) you will also get the
listing of the module used for that hardware.

lsmod is to list the modules used.

Follow this page to xrandr First discover what we have section.

See if the VGA output is seen.

Is it possible VGA is off in the Bios?

I'm afraid I am a bit out of my league here.  I did check bios and there is nothing which seems applicable.  Very few adjustments can be made there.  I did, just in case I didn't understand the naming, change all the defaults, such as sata and svm, to their opposite, but that did not enable the second display, so I reset the bios to default settings.

I tried lspci - vv and don't really understand its output.  Here is that part of the lspci -vv output which I think covers anything that deals or may deal with the video drivers:

Bigpaws, sorry, but I don't understand the direction beginning with  "follow this page to xrandr First..."
