Hmm, this could be worth a try. Right at the moment I seem to have found a workaround. I disabled "Put the display to sleep" and just kept "Put the computer so sleep" after 20 minutes, and this seems to work (but it's still a bit unreliable). Somehow the display sleep and computer sleep were biting each other... may be it's because the Dell screens (yikes!) have their own sleep function built in, and this is interfering with the display sleep command coming from the G5?

Is there a USB connection from the monitor to the computer or something? I have one client that will not sleep when a USB label printer is plugged into it, because the USB keeps tickling it awake...



Ahaa... maybe this is it? There is indeed a USB connection from the computers to the monitors. The students use the USB hub in the display for their USB sticks. This could explain why display sleep is not working. Disabling display sleep and only enabling computer sleep helps somewhat, in that 7 out of 10 machines now go to sleep after the specified time (20mins). The other three machines don't. Uh??? I can't see any difference between the sleeping machcines and those who don't. Nothing plugged into the USB hubs on the screen or whatever...
