Version-Release number of selected component (if applicable):
RHEL6.4-20121203.n.0

Steps to Reproduce: 
This case is optional only for those who have multiport graphics (4-port,
8-port or so) in possession. If you have not such card please remove this test
case from your run.

 1. Ensure the 'nomodeset' kernel parameter is not set in your bootloader
    configuration.
 2. Ensure the file /etc/X11/xorg.conf does not exist, or is a valid file that
    uses the valid driver.
 3. Plug as many monitors as graphics outputs you have.
 4. Shut your system down entirely, then start it up again.
 5. Login a X session.
 6. Run gnome-display-properties


 1. Try to change resolution, hit Apply.
 2. Try to rotate different screens, hit Apply.
 3. Try to change possition of screens, hit Apply.



Actual results: 
No hotplugging, monitor arrangement will not refresh until you run xrandr, or open the display preferences, or hit "Detect monitors" in that dialog.

Expected results:
Verify that rendering on all outputs is ok, with no visible corruptions or
crashes.
