[Launchpad Bug Tracker <1234450@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

I've been using an external screen, (as an extended desktop). When I
travel home from the office, I turn  it off (in Gnome Display manager,
so that only the laptop's primary screen is active), physically
disconnect it, and suspend the laptop to travel.

At home when resuming without an external screen, the Laptop screen
doesn't come back on, though plugging an external monitor to VGA1
reveals a part of the extended desktop. It seems that X is still seeing
the primary LVDS1 screen (attaching a projector seems to show only the
extended desktop,  toolbars menus and programs only appear on the hidden
primary screen).

Sometimes the same issue also affects the laptop from a clean boot
(occasionally I have no screen, though the machine appears to be
booting). Doing a hard reboot once or twice triggers the screen to come
back on.
