Re: How to Run a Command on Screensaver Activation, Only After User Interaction that Session?

I'm trying to work on a home-grown kiosk using Jessie.

I've got 90% of it done, but I need it to logout after a certain time of inactivity, but only after the computer has been used at least once since the last start of X (otherwise it'll just be in a slow loop of restarting X).

In other words, something like:

- boot into X
- sit idly for 20 minutes, 2 hours, 3 days, whatever, screensaver running, until a guest comes up and uses the kiosk
- The guest walks away from the kiosk
- 2 minutes later the screensaver kicks in, and X restarts

(It might also be nice to have a 15-second delay when the guest can awaken the screensaver, aborting the restart.)

I'm having a really hard time figuring out how to do this. Any ideas?

Thanks!

I think I've got the basic logic worked out, but I need some help with the syntax.

In my .xinitrc, I have

export FRESH_X=TRUE

Then I want to have a script that sits and waits for a keypress or a mouse activity; this is where I need the syntax help.

When that script sees keyboard or mouse activity, it will export FRESH_X=FALSE

I'll configure the xscreensaver-command --watch to watch for the screen saver to go BLANK, and when it does to check the status of FRESH_X ; if FRESH_X is FALSE, and the screensaver activates, I can set a 10-second time, check again to make sure the screensaver is still active, and then run my logout.

But I need help with the syntax of checking for a keypress or mouse activity. I've looked at xinput and xev and another tool something like xenv, but I can't figure out the syntax in a bash if/then statement.

Any help would be appreciated.

Thanks!
