RHEL 6.3: Monitor: UNKNOWN ???
Hi All,

I've been struggling with this problem for weeks to no avail.
When I go into Control Center-> Display Preferences my monitor is no longer recognized.

Instead, there is a red box which says "Unknown".
This one problem is preventing me from doing just about everything I need to do my job including setting up multiple windows, using an extra VGA plug in monitor, changing screen resolution.... running X -configure, you name it.

Is there any way to reload the video card drivers in Red Hat Enterprise so that it can detect the monitor?
The only utility I've found that might help is one called system-config-display, but that apparently has a bug and won't run, no matter how many times I've reinstalled.

Anyone ever encounter this before and fixed it?
Thanks much for any help.

Can you post your /var/log/Xorg.log or equivalent?

Can you please provide your hardware detail and check your hardware compatability here

Obviously X is working so X is aware of your monitor. Have you just one monitor or more than one monitor? Is there anything special about your monitor?
