LKBEN11383: Kubuntu problem with dual screen. Screens are always duplicated (mirrored)

Symptom

You change your configuration but the screen is always mirrored

Cause

Most of the time this happens when you boot with one screen in the off status

Solution

You need to delete the following file in your home directory:

.local/share/kscreen

This file should be deleted and afterwards you can reconfigure. After the reconfiguration, the settings will be correct and stay after reboot.

Please note that this solution is probably "Kubuntu version" specific.
