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!
