Reassigning to kscreen developers, because of the crash
KScreen::Output::id.

There is, however, some wiredness going on with "kded_colord.so", most
certainly using synchronous D-Bus calls.

I thought we were pretty clear that synchronous D-Bus call are a no-go
in a kded module. Adding colord maintainer.

Fix crash when embeddedOutput() fails to detect embedded output

Some laptops (probably older models) use 'VGA-*' to identify embedded
outputs, so embeddedOutput() will fail, because it only looks for
modern 'LVDS', 'EDP', etc. In such case, just try to use the output
with lowest ID. It's highly probably that it will be the right one.

We should also try to come up with some really reliable method, instead
of name-based guessing.

Same here. Exact same stacktrace. This is really a bummer because
without KDED, *NOTHING* works. Also a laptop setup with proprietary
nvidia-driver, KDED runs fine until I dock the laptop (and thus add an
external monitor).

Hi
As part of the SRU process in Ubuntu we require testing of our packages before the package is released into Ubuntu.

The kscreen packages to be tested can be found here

@Rohan: There is no more crash at startup with the experimental package.
But kscreen did not works anymore with it...

In the system settings, the display configuration panel reports the
following error:

   "No supported X Window system extension found"

kscreen-console reports the following:

START 
kscreen-console(9742) BackendLoader::init: No KScreen backend set! 
Config::current() took 0 milliseconds 
Config is invalid, probably backend couldn't load

@Rohan

 libkscreen0 was not updated automatically after a simple :  "sudo apt-
get install kscreen".

Now, after an explicit libkscreen0 update request, kscreen works
properly.

Thank's you
