You want to be hooking into something that's already polling for human I/O events (if this were NetBSD, I'd say "wscons") and registering (and then renewing later) a timer on them which, if expired takes action. Maybe the Linux distribution involved makes use of something like SCIM: http://www.scim-im.org/ which looks like it probably provides some hooks for monitoring keydown/keyup mousedown/mouseup. Another decent place to look is the XScreenSaver source; checking the same places it does for I/O information should work, and you could run the process that checks and downs/ups the interface in the same way (automatically forking and sitting in the background till an exit request is passed to it later). -- gabriel rosenkoetter gr@eclipsed.net Attachment:
