Days ago I experienced the following problem https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=202770 because on webpage [1] there are no infos about obligation to enable dbus service in order to let KDE working correctly. [1] https://www.freebsd.org/doc/handbook/x11-wm.html
KDE also needs hald service.
I have a system running KDE with no hald.
(In reply to Benjamin Kaduk from comment #2) > I have a system running KDE with no hald. It's not mandatory, unlike dbus, but it's desirable. hald is still the only backend for Solid (KDE hardware device framework) supported on FreeBSD.
