Twice already when waking my two displays from sleep, the primary display will show just colored static, not the login window. The external display seems fine and shows just a blank screen. If I type in my password, the static goes away and the primary display shows the desktop. I can't reproduce the problem... it just happens (so far, infrequently).

I recently upgraded from an older Intel Mac Pro to a stock Early 2009 Mac Pro with 2 x 2.26 Quad-Core Xeon using the same two displays (a 19" Samsung and a 24" Dell) I had before. The 19" Samsung is connected via a mini displayport to DVI adapter and the 24" Dell is connected via DVI and is the primary display. My Mac never sleeps; only the displays sleep and I have it configured to require a password when waking from sleep or screen saver. I also have the Flurry screen saver enabled.

I basically unplugged my old Mac Pro and plugged in my new Mac Pro to my existing setup (displays, network, keyboard, mouse). This never happened with my old Mac Pro so I doubt that it's a problem with the 24" Dell (unless it's a huge coincidence that it started happening after I upgraded).

I want to reiterate that the 24" display is NOT connected via the mini displayport to DVI adapter, but through the DVI port. This problem happened once yesterday and once today and I've had the new Mac since Monday. I'd say my displays go to sleep about 6 times a day since I go in and out of my office often. The problem has yet to happen when I wake up the display first thing in the morning.
