Hello everyone. I have noticed an issue with my 30" display. Sometimes when I wake the mac pro (2.66, 1900XT, 2gb) from sleep by pressing a key on the keyboard, the white light on the display flickers, but the screen itself never wakes. When I re-sleep the computer by holding the power button on the Mac Pro case down and then wake it again, the display wakes normally. This does not happen often (perhaps once every twenty "wakes"), but I wonder whether it is a symptom of a hardware issue that I should look into further. The problem started before I updated the firmware, and still exists after the update, with about the same frequency. I appreciate any thoughts anyone has on this!
