Comment 10 for bug 29984

I haven't tried this with Dapper at all because I use only stable
releases. And yes, bug still exists with Breezy.

This fault really happens only when monitor is turned off and thus it
cannot offer signal to display adapter.

For reproducing this:

1. Turn off computer and monitor
2. Turn on computer but don't turn on monitor
3. Wait few minutes, until Ubuntu is booted to the login menu. Note: I
don't have standard login screen. So I changed some settings from System
-> Administration -> Login screen setup

General tab
Local: Themed Greeter

Themed Greeter tab
Mode: Only One Theme
Happy GNOME with Browser

Other settings should be in order.
