Hello,
I made the unfortunate decision to check the "Enable screen mirroring" box after connecting my external monitor, and since then, when I reconnect the external monitor, the display disappears and is replaced by the same random colorful patterns on both the laptop screen and the external monitor...
I wonder if it's possible to disable the "Enable screen mirroring" command via command line, or if someone has another idea...
Thanks in advance.

Configuration: Mac OS X Snow Leopard 10.6.2/ Safari 531.22.7

      Hello,

      yeah, but if the screen isn’t connected, the 'layout' tab won’t show up.

      Try connecting another external screen... there must be an issue with yours.
