<pre wrap="">I'm writing a simple application to rotate wallpaper every so often, and

<pre wrap=""><!---->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:<br>
<pre>#Create DCOP clients
import kdecore
import dcopext
dcopclient = kdecore.KApplication.dcopClient()
dcopclient.registerAs("changewp")
dcopapp = dcopext.DCOPApp("kdesktop", dcopclient)
</pre>
and then later we have things like:<br>
<pre>dcopapp.KBackgroundIface.setWallpaper(...)
</pre>
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.<br>
<br>
Here's a simple test program:<br>
<pre>#/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]
</pre>
If I run that from a konsole, I get e.g. <tt>/usr/share/wallpapers/default_gears.jpg</tt>.
But if I run it from a virtual terminal, I get: <tt>None</tt>. And
again: I'm the same user both times.<br>
