Bug 367715

Hey devs,

would be appreciated if you could take a look at this problem. So this happens almost every time after logging into a plasma session:
* one of the screens stays uninitialized, still showing the splashscreen
* the panels, which were setup one on each screen, are now opened one atop another on the other (properly initialized) screen
* the uninitialized screen is unusable (windows dragged over it leave trails, right-click on the desktop/background shows no context menu)

The problem can be fixed by going to Settings -> Display and monitor, doing a disable/apply/enable/apply on the uninitialized screen. After that, all of the panels usually move to the newly enabled screen so they have to be rearranged again. Sometimes after the enabling the screen, plasma also crashes (the panel shows a crash icon). I can send the trace if it's any help.

Please see the screenshot illustrating the problem here: https://drive.google.com/file/d/0BxkpASF8KtrhVGMwZmhpb3QzbUE/view?usp=sharing

Reproducible: Sometimes

Steps to Reproduce:
External monitor connected to a laptop and just login normally.

Actual Results:  
One of the screens, usually the laptop screen, stays uninitialized - showing a splashscreen with an uncompleted progress bar. The panels are stacked one atop another on the initialized screen. When dragging windows on the uninitialized screen, the background is not refreshed (i.e. the dragged windows leave a trail behind them).

Expected Results:  
Both screens initialized with panels on each screen as they were setup in the previous session.

Running latest KDE Neon User (all updates applied).

The laptop has two gfx chipsets (intel & nvidia) - nvidia is disabled, running with i915 driver/module.

The monitor is connected via HDMI (laptop side) -> DVI (monitor side) cable.

I can send further info if needed.
