[X2Go-Dev] Bug#1201: Black window with KDE5 plasma

[Klaus Fuerstberger]

Package: x2goserver
Version: 4.1.0.0-0x2go1.2


When starting x2goclient (linux or windows makes no difference) I only
got a blank, black screen as result when selecting KDE as desktop
environment. Starting a single application, for example xterm, works.
This happens after upgrade to Debian 9 and KDE5. The installation is
running without systemd but with sysvinit.

Some Logfile entries when starting the session:
