Bug Description
Binary package hint: xorg
Steps to reproduce:
1- Plug a monitor into the VGA output
2- Press the monitor switching key (fn-F5)
Expected result:
- Display appears on external monitor, either mirrored or as additional desktop space.
Actual result:
- The external monitor is shown in the Monitors panel, and gets correctly identified (I see Acer 19" or Dell 22", tested with two different screens)
- However, the monitor itself reports "no signal", and displays nothing.
I went as far back as Lucid and the problem still persists, so at least it doesn't appear to be a regression.

I tried powering on the system with a screen already plugged in. In this case, the BIOS takes the external screen as primary, the boot sequence is visible there, and when starting X, the laptop's internal display becomes the primary, showing the desktop and panel, BUT in this case, the external screen does work as expected. So the issue apparently happens only when plugging in the external display on-the-fly.
