5.8 multiscreen problems

[Steven Haigh]

I already had some issues with multiscreen in 5.7, but some things seem
to get better with 5.8 - and also some things getting worse.

Previous bug report:
	https://bugs.kde.org/show_bug.cgi?id=367917

System 1:
	Hardware:	nVidia 1060 with nvidia drivers.
	Screens:	3 x 24" 1920x1080 screens.

Problem:
The main screen (DVI-D) seems to work ok as Folder mode and saves the
settings. The screens on either side of that (DP-1 & DP-5) will not keep
their setting and keep reverting to 'factory default' folder view with
icon rows / wallpapers on logging on.

System 2:
	Hardware:	Dell Latitude with intel graphics
	Screens:	2 x DVI screens via docking station.

Problem:
On logging in with a new user account (an empty $HOME), I get the
'factory default' view on both screens. No panel is displayed. If you
right click the desktop, then Add Panel, nothing displays. doing
"killall plasmashell && plasmashell &" via krunner (Alt + F2), then
upon
loading plasmashell, I get the normal panel plus an extra panel for
every "Add Panel" selected.
