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.
