I'm not 100% sure if it's related to this bug but since I upgraded to unity 3.8.16-0ubuntu1~natty3 I have trouble with my external LCD screen.

I can get to the login prompt but once authenticated, the screen goes black. When this occurs, I still can have my display back if I unplug my external monitor, my laptop's screen goes on and all work fine on this screen.

Note that I normally only use my external monitor as my primary and my laptop's screen is turned off by default. This seems to trigger the bug. I was able to find workaround to have my external LCD working :

# Set my external LCD as primary
$ xrandr --output VGA1 --primary

# Turn off laptop's screen
$ xrandr --output LVDS1 --off
