Description Mikael Steen Springer 2016-02-10 13:40:35 UTC 
Application: plasmashell (5.5.4)

Qt Version: 5.5.1
Operating System: Linux 4.1.15-8-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

Using nvidia-settings I tried to disable my laptop monitor since I only want to use the two external monitors attached to the laptop at this time. This failed, producing weird problems where one of the external monitors and the laptop monitor went black and the primary desktop moved to the remaining monitor. When I choose to cancel this setup in the nvidia-settings tool Plasma crasched.

On the whole, Plasma 5 does not work well with multiple external monitors on my laptop (a dell precision with an nvidia card). It is more or less impossible to configure the system to use the two external monitors when docked and turn of the laptop monitor. I have managed to succeed once but after a Plasma chrash I cannot get it to work again.

I have KDE, Gnome 3 and XFCE installed on the same laptop. Gnome and XFCE both manage to configure the monitors correctly (turning of the laptop monitor and turning on the two external monitors, when docked).

This used to work fine in KDE 4.

The crash can be reproduced every time.
