You may need to call the dbus command with Code: run-standalone.sh dbus-send --type=m... Pop all your command into QBW and test to see if they work. The Advanced settings have a multi line edit box which makes it much easier to edit your commands. QBW scripts are basically normal XTerminal scripts so you might find it easier to test in XTerminal, but the Advanced settings will also display the output if you press Run
run-standalone.sh dbus-send --type=m...
