Comment 14 for bug 554069

Since there seems to be no intuitive way to stop xscreenserver in the Kubuntu settings, it is very confusing for a user that the screensaver cannot be disabled. I believe the screensaver functionality must be de-coupled such that there are no side-effects to another desktop only because there are more than one desktop installed.

A solution of xscreensaver not being installed with a Kubuntu (KDE) desktop fails to work correctly if other desktops are installed in addition to KDE. Furthermore, the xscreensaver daemon should actually be only be started when the xserver is started with a desktop which needs it. It needs to be started by the xserver, since otherwise the logout and login into another desktop does not satisfy both configurations chosen.
