    Pro tip: When planeside checking your carry-on, be sure to take your Macbook out of the front pocket first :-(

    Anyway, my built-in display on my Macbook is totaled, but the rest of the machine is working as well as ever. I'm hooked up to an external display, but each time my computer hibernates or is rebooted, I have to go through the drill of setting my external monitor as the primary display - which is pretty difficult since the display settings window initially shows up on my busted monitor. I've gotten closed shell mode to work (i.e. booting machine, immediately shutting lid) which is great for OSX, but I'm triplebooting Win7, Ubuntu and OSX and when Win7 comes up, the Macbook display remains black but my machine acts if it were still on (my mouse goes over there, all my icons, etc are over there).

    Is there a way to make the external display function as the ONLY display by default? In other words, is there a way to get my Macbook to stop detecting my broken display?

    I haven't done this in a long time, but if I remember correctly...

    Go to System Preferences > Displays, click the "Adjustment" tab. You should see two images, one representing your MacBook and the other, your external display. Click and drag the tiny menu bar from the MacBook's display image and drop it onto the image for your external.

    This will make your external the primary display.
