I'm trying to change my wallpaper to a random image using Indrajith Indraprastham's suggested script here:
How to change desktop background from command line in Unity?
When I run the script from a terminal window, the bg changes just fine, but when it's run from cron, I'm mailed this error:
(process:21901): dconf-WARNING **: failed to commit changes to dconf: Error spawning command line 'dbus-launch –autolaunch=00216c114dcf433c9bb9009985d607d6 –binary-syntax –close-stderr': Child process exited with code 1
I would appreciate any suggestions.
