I installed REHL 6 (30 day demo version) on a system that already had 2 identical graphics cards. There are 2 identical monitors conneted, but only 1 monitor is detected. I tried System -> Preferences -> Display. It only shows 1 monitor, and "Detect Monitors" doesn't seem to do anything. Any idea what might be wrong, or how I might fix this? Is dual monitor support crippled in the demo version? I didn't find anything in the documentation that said it wouldn't work.
I'd like to add that this system used to run Solaris x86 with these 2 graphics cards. I'm looking at moving to RHEL if it can do everything Solaris can.
