Bug Description

My setup:

A notebook with the TV connected via HDMI. It is setup as a second screen and works fine generally.

What happens:

I work normally.
Go away for a while, the monitors get turnt off.
Television eventually turns itself completely off.
I come back and move the mouse.
The notebook screen does *not* come back on. Television clearly cannot turn itself on.
I type password.
The notebook screen still doesn't turn itself on.
I turn the television on.
Television shows that no signal comes through.

How i resolve the situation:

I press Ctrl+Alt+F1 to get to the first terminal (it comes on the television screen)
I then press Alt+F7 to get back to the graphical environment

What i expect to happen:

When i move the mouse, the password prompt should appear on the notebook screen.
When i type it in, i should have the working one screen environment.
When i turn the tv on, i should get the normal "new screen" prompt, where i select where to connect it dimentionally.
