I am using two monitors for some time now, and decided to use both monitors as mirrors, mostly because the menubar doesn't show on the extended monitor.

So I selected enable mirror on the screen icon on the menu toolbar, and boom! Big Mistake.

Now, I don't see ANYTHING but garble graphics on both the laptop and monitor.

I need help in undoing this.

When I reboot without the external monitor all works fine but the options for multiple monitors don't show, including the mirror option.

I have Iatkos 7 running on a Lenovo X61 tablet with Intel Graphics. I updated everything except the core system so I am still 10.5.7
