Several thoughts come to mind...

1.  What desktop are you using?  GNOME. KDE, xfce, something else?
2.  Did you try going back to a working kernel?
3.  It seems as if you're saying you've booted without the monitor attached and plug it in later?  Yes?  If so, have you tried booting with the monitor already attached?   Or, attaching the monitor and then logging out/in?
