Installs of KDE on my machine make my WD spin up and down again and
again. For Xfce4 installs with GVFS this happens too, for Xfce4 installs
without GVFS it doesn't happen, but after running K3b something is
started that makes the WD spin up and down again and again too, for
Xfce4 installs without GVFS. IOW there at least is something that wakes
up Green drives, for GNOME and GNOME forks and Xfce it's GVFS. I don't
know what does cause it for KDE, but something does cause this issue.
