[SOLVED] Twinview, gnome and compiz

[elija]

I am running two monitors in a twinview configuration. Yesterday (and before) this was running absolutely perfectly.

Screen resolution = 3360 x 1050
Windows draggable between monitors
Windows maximized across both monitors
Gnome panel spanned both monitors
Compiz effects spanned both monitors (Desktop cube etc)

Then I shutdown as normal last night and this morning I find that

Screen resolution = 3360 x 1050
Windows draggable between monitors
Windows maximized on an individual monitor
Gnome panel is only on one monitor
Compiz effects show on each monitor. So for example I get two cubes.

I have tried disabling twinview, enabling Xinerama, switching to and from separate X screens, each with a restart of X as and when requested.

How do I get back to what I had yesterday?

This is my xorg.conf

Got It!

I stopped trying to use the configuration tool and added two simple lines into my xorg.conf. OIne quick Ctrl + Alt + Backspace later and all is well

You truly haven't seen funky until you see the desktop cube spanning multiple monitors at a ridiculous resolution.
