Bear in mind my profile is desktop/plasma/systemd ...

This is very informative, but it blows up on me ... I've checked that 
wayland is in my use flags so that should all be okay ...

# XDG_SESSION_TYPE=wayland dbus-run-session startplasma-wayland
... startplasma-wayland not found ...

# emerge qtgreet
emerge: there are no ebuilds to satisfy "qtgreet".

So you've massively helped in that I now know much better how things fit 
together, but unfortunately you've also been no help at all in that the 
stuff you've pointed at doesn't work ...

Where do I go from here ...

Cheers,
Wol
