Description of problem:
When the screen lock is active for some minutes, KDE seems to forget about the display configuration of a multi-screen setup and overlays both screens on top of each other.
Version-Release number of selected component (if applicable):
Most of the times.
Steps to Reproduce:
1. Lock the screen (or have it locked by timeout)
2. Wait a while (>15 minutes)
3. Screens are mirror, instead of side-by-side. Even after unlocking the screen again.
Screens are configured overlayed (screen one exactly over screen two).
It is possible to re-configure them.
Screen settings are kept.
