What Guy suggested is neither obvious nor unfeasable. All you need to do is to take a look at the source of some automatic screen saver, and find out how the "screen saver extension" is used. > Btw: Using xautolock to run a program after x minutes idle time is not > enough because I need a per-minute sample wether the user is active or not > to be able to create true usage profiles. And I need to know also (end > especially) about extended periods of inactivity. Another option is to write a tiny xlib program which gets copies of events you're interested in (e.g., keyboard presses, mouse clicks, window creations) and then you can estimate inactivity (e.g., 10 minutes without any of these events happening is probably a coffee break). Doing this is not unfeasable either (shouldn't take more than a few hours if you know XLib programming), But whether it's worth your trouble is up to you. Of course, the value of all this depends on how important it is for your users to deceive your checking program. For example, if you want to deduct pay from someone who took a break longer than 15 minutes, be sure that one of your users will invent a method to mess with your program (e.g., the old "book over the numeric keypad" trick, or using fake events). If you use my event capturing idea, you can fight back: ignore send_event events (see XEvent(3)), ignore repeating of the same key, and so on. -- Nadav Har'El | Monday, Feb 4 2002, 22 Shevat 5762 [EMAIL PROTECTED] |----------------------------------------- Phone: +972-53-245868, ICQ 13349191 |Ms Piggy's last words: "I'm pink, http://nadav.harel.org.il |therefore I'm ham." ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
