CentOS - Sep 2018 - Centos7/Kde4 freeze

Hi

I have a fresh install of centos 7.4 with KDE on a laptop (latitude 5590) 
connected to a DELL WD15 dockstation with an additionnal screen.
It works quite well, I have 2 screens side by side (default config), but....
If I add a second menu bar for the screen connected to the dockstation (KDE 
allow for this) it is not possible anymore to start a kde session if the laptop 
is not connected to the dock station (eg: at home), kde freeze and never show 
any menubar. I have to use gnome to login and remove the .kde directory.

Is there a way to avoid this ?

Thanks

Patrick

This problem seams more general... adding an application to the
"favorite" when connected to a docks station produce the same freeze
when laptop is standalone. The workaround is to to do this BEFORE
connecting to the doc station the first time. :-(

I found also some problems with kwallet when seting up a wifi
connection: it was requesting for a password but kwallet/centos was
unable to focus in the popup windows to allow entering the
password...:-\ (standalone laptop at this time)

kde seams to have some trouble in dynamic screen configurations. I
switched to Xfce which just runs fine and do the job!
