I too have an inordinate amount and similar problems with multiple displays,
using Display Port 1.2 / MST. This system runs Kubuntu with the Plasma 5.5
backports
plasma/krunner crashes have gone away, mostly, with Plasma 5.5 but multiple
display setup is still a pain. The issue occurs during cable plug-in OR
display setup and is especially evident when moving from a multi display setup,
to laptop only, then back to a multi display setup.
Either -
+ I get one display blank (sometimes with a working mouse cursor) OR
+ the display splits in half and becomes frozen, with the left half on the
right and the right half on the left OR
+ the display half-configures and the desktop becomes unresponsive, although
the mouse cursor might move OR
+ configuring and moving screens, then hitting Apply in kscreen causes the
desktop to become unresponsive OR
+ upon login, all displays are blank.
Switching to runlevel 1 and checking top, the system is just happy idling away
with no load. Interestingly when dropping to another runlevel, all 3 screens
including the 2 in the MST chain happily clone each other even when Plasma/KDE
is finding it hard to configure the setup or crashing.
In all instances, removing the contents of ~/.local/share/kscreen/ and then
running a sudo killall sddm, then signing back is the only way to get back to
square one and start again.
Once it is setup, it works flawlessly for the entire session without crashing,
I'm especially pleased with the MST support.
I'm really happy to help test any possible or proposed fixes in order to get a
stable multi-desktop system working. Qt coding is not my forte.
