Yes, that would figure, although there's a trick to avoid that too. > It was very hard for me to find information about using KDE application > outside of Plasma. That figures, the plasma team guards their work a bit jealously (or at least that's the impression one can get). > How to use the plasma-integration platform theme plugin if not using Plasma5 > desktop? Easy: set QT_QPA_PLATFORMTHEME=kde; you should already have the plugin itself since you have the Plasma5 desktop stuff installed . It can help if you also set KDE_FULL_SESSION=1 and KDE_SESSION_VERSION=5 . If you do that, KF5 applications should behave as if they're running under a Plasma5 desktop. There should be no or almost no drawbacks, because that desktop environment isn't required to run those applications. This is exactly what I do on a Kubuntu 14.04 machine that still has a good old KDE/Plasma4 desktop, and I do something similar on my Mac where it is evidently not possible to run a full Plasma desktop environment. >From time to time you may get messages about services that aren't running or >found (kactivities, for instance).
