Comment 12 for bug 856892

This enhancement is needed for sure in live show environments.
We can't use Ubuntu with Unity in gigs and generally in any other place that's not an office environment.

In a theatrical show or a concert you never want to risk displaying any OS interface element in any case, never ever, there are poetics requirements there!

Hiding the menu bar when a full screen application is running is not enough, we never know what's going to happen in a live show, a scheduled scene may suddenly change for any kind of problem, we may need to relaunch an application with different parameters, our experimental applications may also crash, and we are subject to human errors too... in any of these cases a black projected canvas is the most desiderable transitional failure! ;)

I'm all for an option to disable or hide launcher, menu, notifications and any possibile OS interface element from secondary monitors.
