Now I have opened the system settings, entered the Universal Access section, and selected the Pointing and Clicking tab. On this tab I have now turned on "Simulated Secondary Click" and then I tried again on the desktop background. Independent how I adjust the slider I do not get a right-click menu. On which package do I have to report this?
OK. I had never enabled automatic click.
