Are you connecting the VGA plug to the mini DisplayPort adapter while the latter is currently plugged into the MacBook? How about connecting the VGA cable to the mini DisplayPort first and _then_ trying to plug the mini DisplayPort adapter into the MacBook. The latter might work better for hot-plug detection.
I have been having this problem for some time now. I'm going to perform a complete re-install of OS X this week and see if its an OS problem. My adapter worked fine originally, well I say fine, I still have the flashing monitor issues but all of a sudden it causes my system to completely hang now resulting in a grey screen.
I will re-install and let you all know.
Me too. I have had this problem for the last 9 months since I bought the Unibody MacBook. Every time I connect my external display I get a system freeze for about a minute (cannot move the mouse pointer etc.). Then about one time in 10 it completely crashes the machine and I have to forcibly restart it. All my software is up to date including the display port adapter.
I can't believe Apple haven't got their act together and fixed this one in all this time. C'mon Apple, do something about it, given the number of people it seems to be affecting.
+1 : same problem
Screen : NEC LCD22WV
Context : plug mini-displayport to VGA adapter (I always plug LCD VGA cable to the adapter, and then adapter to my macbook)
System log during system crash (seems to be graphic crash only):
Sep 15 14:13:02 x kernel: PM notification cancel (pid 1936, Safari)
Sep 15 14:13:02 x kernel: IOPMrootDomain: idle cancel

And then the normal reboot messages :

This problem seems to be very common.
No surprising : many users use mini display port, at work or at home, in order to use a large LCD screen.
Last message is from one month now : is there any news, reporter bug number, or (I'm optimistic) a solution ?
Thanks to any people replying.
Thanks to Apple to fix it very soon, as it's not acceptable to crash when you only plug a LCD display ...
