[QUOTE="steveb, post: 760643, member: 75115"] I have the same problem, but can add the following... Until upgrading late October 08 to an aluminum MacBook, I had a black MacBook (but the same external monitors and the same version of OS X), and did not experience any such problem. As soon as I upgraded my machine to the new MacBook, I found that frequently when the laptop put the screen into power save, the screen would either 1) not awake (though the laptop would---rendering most windows inaccessible since they were "displayed" on a blank external monitor), or 2) would awake into a nasty state with flashing randomized black and white pixels. In both cases the solution was just to unplug and replug the mini-port-to-DVI adapter. This has the annoying side affect of reorganizing my windows. Any further insight into this problem would be appreciated. As far as I can discern, it is not particularly dependent on the external monitor (I routinely experience it with two different monitors at home and work), and is particular to the Aluminum MacBook (since the problem only arose when I moved over from a black macbook, even with the same OS X version).
