100% right Jim, that's exactly what I need to do. Basically, we're rewriting a Windows application to run on Linux, so I'm supposed to emulate that functionality of being able to go idle and then wake up.
A little more detail -- the way I'm required to do this is through a web page connected to the computer via a tablet, so somehow I need to figure out how to make the computer go idle, and be able to wake it up from idle. The only way I can think of to do this is to call a command line script from PHP,
But, that brings us back to square one -- there are a million commands to turn off the monitor, but nothing to go idle. I don't care if I have to write a complicated script (as long as I can get a good idea of where to start, which I still don't have), but I don't really have a choice here in reinventing the wheel, do I?

update(n) Tcl Built-In Commands update(n)
__________________________________________________________________________________________________________________________________________________
NAME
update - Process pending events and idle callbacks
SYNOPSIS
update ?idletasks?
_________________________________________________________________
DESCRIPTION
This command is used to bring the application ``up to date'' by entering the event loop repeatedly until all pending events (including idle
callbacks) have been processed.
If the idletasks keyword is specified as an argument to the command, then no new events or errors are processed; only idle callbacks are
invoked. This causes operations that are normally deferred, such as display updates and window layout calculations, to be performed imme-
diately.
The update idletasks command is useful in scripts where changes have been made to the application's state and you want those changes to
appear on the display immediately, rather than waiting for the script to complete. Most display updates are performed as idle callbacks,
so update idletasks will cause them to run. However, there are some kinds of updates that only happen in response to events, such as those
triggered by window size changes; these updates will not occur in update idletasks.
The update command with no options is useful in scripts where you are performing a long-running computation but you still want the applica-
tion to respond to events such as user interactions; if you occasionally call update then user input will be processed during the next
call to update.
