Binary package hint: xorg

Steps to reproduce:
Unplug external display from VGA port (assuming both monitors were working fine)
Click "Detect Monitors" on the Monitor Preferences panel

At this point, the screen either goes all black or black with white lines.
Mouse cursor is still visible and can be moved around, cursor also changes when hovering link, etc...
