You have been subscribed to a public bug: Dual monitor works fine with additional drivers fglrx-updates. After activating skydome, I suppose, it worked like the following: It comes with two monitors up, after logging in, both monitors will go black until I plugged of the VGA Monitor and switching with Ctrl-Alt-F8 and Ctrl-Alt-F7. Then the first monitor HDMI comes back again. I cann finally replug the VGA Monitor and is detected well. The bug is similar to the unmaintained #1124328.
I have resetted graphics adapter and unity and compiz and xserver several many times. Behaviour is now stable.
