Application: systemsettings (4.11.16)
KDE Platform Version: 4.14.5
Qt Version: 4.8.6
Operating System: Linux 3.19.1-desktop-2.mga5 x86_64
Distribution: "Mageia 5"

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

My second screen is not displaying propperly and mouse is sluggish.

While in system setting I notice that my second screen resulution is limited to 1024 X 768 and my main screen is 1366 x 768. When I unify the screens they both go to 1024 X 768 but laptop screen is blank when I enable the laptop screen then the System Settings crashes. 

Right now I have 2 seperate screens but the mouse will only display in the laptop screen while I am typing this in the VGA screen.

My main concern is getting the VGA screen to display propperly and the mouse to respond propperly

Laptop is Lenovo g560e
VGA screen is iivama ple2202w

Distro is Mageia 5 Cauldron with latest updates applied

Hope this helps

Thank you
