Well, I hadn't originally intended to set up X, so I was a little

And Plasma is a dependency of what? Again, this is down to me not fully 
understanding everything, but surely if I selected the 
desktop/plasma/systemd profile, that should call in the basic plasma 
packages by default? Maybe even the kde ones?

(Having re-read the KDE page, it's suddenly making a lot more sense, but 
that's with hindsight. But am I right that the profile modifies the 
system set of packages?)

I'm currently emerging kde-apps-meta, because I discovered that plasma 
(once I'd got it working) was missing all sorts of things - like 
konsole! But that kde page you pointed me at only mentions it in passing!

It's the classic problem that man pages are very good as reference, but 
if you don't know what they're talking about they are very bad at 
enlightening you.

A "dummies guide to plasma" would have been very useful telling me the 
packages I needed to emerge and why would have been very useful. Now I'm 
getting my head round it it's all falling into place, but I've been 
unable to see the trees for the forest :-)

And I'll probably be tearing my hair out screaming because I'm straying 
into unknown territory again :-) I doubt many people run multi-seat, so 
that'll be fun ... (and I gather some of these greeters don't support 
it, either :-(

Thanks. At least I'm back on familiar territory there.

Here's hoping for a lot more foresight :-)
