Settings are like that: $QT_QPA_PLATFORMTHEME = kde $QT_LOGGING_RULES = *.debug=false $QT_PLUGIN_PATH = /home/florian/.kde4/lib/kde4/plugins/:/usr/lib/kde4/plugins/ KDE_FULL_SESSION and KDE_SESSION_VERSION=5 are not set. If they are set, everything seems to work. florian@horus ~ % dolphin "Session bus not found\nTo circumvent this problem try the following command (with Linux and bash)\nexport $(dbus-launch)" Of course, dbus is started using systemd / logind, other applications depending of dbus are working. tried that multiple times, crashes every time. At some point it seems to start whatever was missing and works. KMail: florian@horus ~ % kmail org.kde.pim.akonadicontrol: Unable to register service as "org.freedesktop.Akonadi.Control.lock" Maybe it's already running?

It's probably QT_QPA_PLATFORMTHEME=kde that gives the file dialogues, and the two others, that makes kmail and dolphin actually work. > > >Is there some KDE wiki site that can be used to document that?

Especially since KDE is not the KDE desktop anymore, but the KDE software collection, which, as far as my perception goes, should be independent of the Plasma desktop. Plasma can't and doesn't want to be something like i3 or awesome, but if I have to choose between i3/awesome and dolphin, I would take the first. Though after I had these problems already with dolphin, I tried other file managers (pcmanfm and thunar) but still like dolphin the most. I also use dired of Emacs, but thats not something for everyday use. BTW: Do you have any idea how to set dolphin to select on double click, not single click. I was looking at `kcmshell5 --list` but couldn't find the right module. Or is there even a command to get the KDE system settings GUI? Best Wishes, Florian
