Experiencing this bug with a Sony Vaio VGN-FE41Z which has an LVDS internal monitor and an external DVI-D connected via the docking station. During start-up output is mirrored to the external monitor.
The display 'stops' with the plymouth splash screen and the message "Press C to cancel checking disks". The Xorg log shows it started and got 'stuck' just after the nouveau driver probed the displays.
Using Alt+SysReq+K will kill all the processes on tty7 and restart Xorg which then presents the GDM greeter correctly.
Changing the kernel's command-line via the GRUB menu (edit entry, delete "splash", press Ctrl+X to start) also works around the issue.
