It works on the standard (in my case Unity) desktop and even in XBMC.

Besides the possibility of using the right-click emulation of Onboard one can right-click by holding one finger on the place where one wants to right click, and while holding the finger down tapping with another finger on an arbitrary place of the touch screen and after that sliding the held down first finger through the context menu to the desired item and releasing there, which leads to the item being selected.

The right click on the touch-operated Ubuntu Desktop is not completely unimplemented.
