Review request for kde-workspace and Oswald Buddenhagen.


Changes
-------

readd FindSystemd.cmake (erroneously dropped), one more trivial fix


Repository: kde-workspace


Description
-------

This patch implements dynamic multiseat in KDM. It follows the description in:
http://www.freedesktop.org/wiki/Software/systemd/writing-display-managers/

In case systemd is no found at compile time, nothing changes. If logind is not running, nothing changes. If no additional seats have been configured (some Plugable USB-GPUs are automatically added as additional seats), nothing changes.

In case there are additional seats beyond seat0, a reserved display is promoted to a local static one (and demoted if the seat is removed) and a new X-Server/greeter is spawned.

The code has been tested extensively, with a combination of [Radeon dedicated GPU|Intel iGPU], [Intel iGPU|Displaylink USB GPU] and others. For history of this patch, see https://bugzilla.redhat.com/show_bug.cgi?id=884271 and https://bugzilla.redhat.com/show_bug.cgi?id=975079
