Description Andy 2015-08-11 07:04:50 UTC

Application: plasmashell (5.3.2)

Qt Version: 5.4.2
Operating System: Linux 4.1.4-1.ga37e14f-desktop x86_64
Distribution: "openSUSE 20150807 (Tumbleweed) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Try to switch from the built-in LVDS1 notebook display to an external monitor that is connected via a docking station that extends the internal HDMI2 port.

xrandr --output HDMI2 --auto --primary --output LVDS1 --auto

The crash is reproducible and occures regardles which render engine (openGL, xrender) is used. 

BTW: This worked flawlessly with plasma 4!

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

could you install debug symbols for plasma-framework please

>Try to switch from the built-in LVDS1 notebook display to an external monitor that is connected via a docking station that extends the internal HDMI2 port. xrandr --output HDMI2 --auto --primary --output LVDS1 --auto 

That command isn't switching, it's turning on both monitors, no?

Created attachment 93997 [details]
stacktrace with debug symbols

Actually the command used was this:
xrandr --output HDMI2 --auto --primary --right-of LVDS1 --output LVDS1 --off

Since the konsole app also crashed I erroneously typed the wrong command in the bugreport. Sorry for that. Please note that the command contains a flaw: "--primary --right-of LVDS1" doesn't make sense if LVDS1 is off.

This bug seems to be related to Bug#345544 which is apparently fixed in Plasma 5.5. how is this still happening with ubuntu 7+ months after report?
is there a simple way for a noob to get Plasma 5.5 running on a kubuntu machine?
I am so sorry I let go of my LTS distro. wont be doing that again after 16.04
Maybe it's finally time to give up on ubuntu altogether
