Hi,
kf5 seems not usable when adding it to a lxde siduction installation. With old kf5 and plasma5.2 stuff this was possible without any trouble.
system is up-to-date
Metapackage plasma-desktop is installed, kwin, sddm, breeze and further stuff is installed, this should be enough to get a working kf5 session.
But I only get a crash dialog of kinit5.
Login lxsession, openbox or icewm works, so it has not to do with wrong xserver configuration.
And it also has not to do with kf5 code, because manjaro and antergos give me a current kf5 and plasma 5.3.1, with is working without any trouble, apart from a bug, when trying to modify special window settings.
My next try will start with an up-to-date siduction kde4 installation. I'll report here.
Kind regards,
Holger
