    How can I disable Mirroring when I can no longer see the Mirror Display checkbox?

    Dell Hackintosh.
    Running Snow Leopard 10.6 (successfully).

    I successfully hooked up my Viewsonic VA1912w display to my hackintosh netbook and it worked fine as an Extended Display. Then to my chagrin I tried Mirroring the displays and now I only get random changing vertical bars and colors on both displays (no visual clues, icons, or anything useful).

    How do I switch back to Extended or turn off Mirror? I cannot get to the Mirror check box because all I see is random vertical bars and stuff.

    Is there some sort of control-tab key combination that will let me fix things?
    Or can I use Terminal to turn on Extend or something?

    HELP

    I don't have an external display connected right now, but you could try this:
    Open Spotlight via CMD+SPACEBAR, enter "Sys", press Enter, press CMD+F, enter "dis", use the ArrowDown key once, press Enter, press Tab, press Spacebar, press Tab, press Spacebar.
    That should turn mirroring off, though you might need to press Tab twice before the last step (pressing Spacebar).

    Disable Hackintosh Mirroring if stuck with garbled screens

    I found this posted at a Dell Mini forum. It actually worked!

    this what I did(OS X 10.6.2 nbi 0.8.3 RC4):
    Thank you so much, I finally got it to work using this method where all others were unsuccessful.
    Details of what I did:
    Turned on Voice Over from Universal Access
    Opened display settings with focus on Searchbar (if you lose focus during switch, random clicking in the area may work as well to find it)
    Pressed Tab key once to hear "Display tab 1 of 3"
    Pressed Right arrow once to go to "Arrangement tab 2 of 3"
    Pressed Spacebar to select the tab
    Pressed Tab key until you hear "Checked Mirrored Displays Checkbox" (or similar)
    Pressed Spacebar to uncheck
