Description of problem:
With the fglrx driver (vendor-supplied) and nomodeset not enabled, the login screen appears, but after login the screen goes blank and monitors go into powersave mode.  Hard shutdown needed to reboot.
Setting the nomodeset parameter allows it work as expected (goes to a user desktop)
Logging a bug here as requested by the "common f12 bugs" page on fedoraproject.org.

Version-Release number of selected component (if applicable):
Catalyst 10.5

How reproducible:
Easily repeatable

Steps to Reproduce:
1. Boot without the nomodeset kernel parameter
2. Login
3. Blank screen
Actual results:
Blank screen

Expected results:
Progression to user desktop (gnome)

Additional info:
This was an upgrade from F11 to F12 using preupgrade.  Older xorg.log files say they can't find an fglrx driver, but that's likely because one for F12 wasn't installed until after the 2nd or 3rd or 4th reboot.  (I had other issues as well relating to AIGLX and Xinerama that worked under F11 but not F12)  I needed to remove the xorg.conf file altogether to get to a desktop at all so I could get the newest driver (it worked, but was slow--nomodeset /may/ have been needed as well there--will try to recreate and update the bug).

Thanks for the report. We are sorry that we cannot help you with your problem, but we are not able to support binary-only drivers. If you would be able to reproduce this issue using only open source software, please, reopen this bug with the additional information, but in meantime I have no choice than to close this bug as CANTFIX (because we really cannot fix it).
