That last step is the problem. I get the following error...

What do I need to do to allow "geeqie" to open up in an X window as
user "waltdnes".

You could let it know which display to use in your script, something like:

export DISPLAY=:0

However, it gets more complicated if a user is not logged in whenever the script happens to run and if the display is on :1 or some other value. You would probably need to fish for $DISPLAY using awk or something similar and feed this into your script before your '/usr/bin/geeqie %u'. Someone more knowledgable on scripting languages will hopefully advise.

The Gentoo install suggested using "cronie". I want to run a script
daily as local user. The config I want is...

35 7 * * * waltdnes /home/waltdnes/pm/check4update/check4update

I did some RTFM...

* There is no "man cronie" but there is a /etc/init.d/cronie
* There is a "man cron"
* There is a "crond" and an "anacron"
* There is "/etc/crontab" and "/etc/anacrontab"

My head hurts. Which config file do I enter the config into, and are
there any initialization steps? Is there a simpler cron program, if
that would help?
