Bug Description

After a reboot, syslog reports:

Feb 18 20:16:52 lat61 gnome-session[3090]: ** (gnome-flashback:3185): WARNING **: Could not assign CRTC to outputs, ignoring configuration
Feb 18 20:16:52 lat61 gnome-session[3090]: ** (gnome-flashback:3185): WARNING **: Could not make default configuration for current output layout, leaving unconfigured

From the perspective of a user, I can't see anything behaving wrong for the moment. Dual screen works correctly (Had to reconfigure screen resolution after hwe upgrades).
