I'm writing a simple application to rotate wallpaper every so often, and
I want to run it as a cron job. The basic structure is pretty simple,
and it works fine if I run it in a shell under KDE. But when I run it as
a cron job, it does not connect to the DCOP server. Is there some way to
tell the script which DCOP server to connect to?

Maybe try dcop --user $username .

Sorry, that wasn't clear. The program I'm writing is in Python.

Yes, but it should be running under cron as the same user you're testing it as 
(the user who owns the display and is running KDE).

Your application should be based on KApplication, and can use 
KApplication.dcopClient() to connect to the DCOP server.

Here is the relevant part of the application as it presently exists:

#Create DCOP clients
import kdecore
import dcopext
dcopclient = kdecore.KApplication.dcopClient()
dcopclient.registerAs("changewp")
dcopapp = dcopext.DCOPApp("kdesktop", dcopclient)

and then later we have things like:

dcopapp.KBackgroundIface.setWallpaper(...)

As said, if I run this from a konsole under KDE, it works fine. But if I CTRL-ALT-F1 and open a terminal outside KDE, then it doesn't work, despite the fact that I'm running as the same user.

Here's a simple test program:

#/usr/bin/python
#Create DCOP clients
import kdecore
import dcopext
dcopclient = kdecore.KApplication.dcopClient()
dcopclient.registerAs("changewp")
dcopapp = dcopext.DCOPApp("kdesktop", dcopclient)
print dcopapp.KBackgroundIface.currentWallpaper(1)[1]

If I run that from a konsole, I get e.g. /usr/share/wallpapers/default_gears.jpg. But if I run it from a virtual terminal, I get: None. And again: I'm the same user both times.
