Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

I have a dual-head setup running Ubuntu 13.04 with Gnome/Unity (the default desktop). What I'm trying to achieve is to display Firefox in "fullscreen" mode (e.g. hit F11 after it is launched), and have Firefox be displayed as a single window across both screens. I've dug every possible setting in Gnome and can't find out how to have fullscreen span across the whole desktop.

I have an nVidia video card with the latest driver (313.26) installed, and TwinView enabled. I tried messing with the "NoTwinViewXineramaInfo" option but to no avail.

Is what I'm trying to accomplish even possible on Gnome/Unity? If so, how must I configure the desktop to achieve it?

Are you sure that's what you want? SuperUser will be | split right down the middle between the two monitors. –  Robert Harvey May 3 '13 at 21:11
@RobertHarvey: Yes, the behavior you describe is exactly what I want –  Fred May 3 '13 at 21:13
nVidia appears to have something called SurroundView that will achieve what you want. –  Robert Harvey May 3 '13 at 21:21
@RobertHarvey: SurroundView is actually a technology from ATI, not nVidia: –  Fred May 5 '13 at 18:13
I guess I got them backwards. There's a corresponding technology that nVidia offers, if you look for it. –  Robert Harvey May 5 '13 at 21:19
