OK, I'm still on kde4 here, on gentoo, so it's unlikely I'd be able to 
help much.

(Tho I have the non-conflicting parts of a minimal kf5/plasma5 install as 
well, for easy testing.  Just a few conflicting packages to switch out 
when I have testing time.  I tried some time ago, and plasma5 had some 
sort of problem with my graphics, might have been the fact that I run 
triple monitor myself.  So I waited and tried again.  Less problem, but 
still a problem.  Last time I tried, it almost worked, but I had a 
workaround setup, a read-only activities-manager-config, for a problem 
with kde4 that I forgot about, as that's one of the few kde4 things that 
already moved to $XDG_CONFIG_HOME from the previous $KDEHOME location, 
and I had only moved the old $KDEHOME location for testing, so the 
workaround for kde4 broke plasma5.  But by the time I got that far it was 
already late and time to go back to an actually working config, so didn't 
actually have a chance to remove the workaround and try again.

However, I'm a heavy customizer and after getting so close to working  
plasma5 last time, I realized that even if it did work, it'd take quite a 
bit more time to get it configured to something actually reasonably 
usable for me... and that's time I don't really have ATM, so I've not yet 
tried again.  But work typically slows down after Christmas, so I hope to 
have time to actually test it again then, hopefully get it working 
properly, and then start reconfiguring stuff.  I'm figuring at least a 
solid day, probably two and possibly three, before I have things 
generally configured to my liking.  kde3 to kde4 took me over 100 hours 
of work to switch, but that was because so much kde4 stuff was still 
horribly broken when kde quit supporting the kde3 stuff that actually 
worked, and I had to find alternatives, sometimes hacking up my own 
solutions, and configure them from scratch.  So the kde4 to kf5/plasma5 
upgrade should be much easier, both because I'm off of kde for so many 
things now due to breakage at the switch and kmail's breakage when it 
jumped the akonadi shark in the middle of kde4, so there's less to break 
and less to configure, and because by all reports, they're being less 
insane with dropping support for the old versions until the new ones 
actually work, this time around.  But as I said, I'm still figuring two 
days at least, which means I need a good solid two-day minimum block of 
time free to do the upgrade and reconfigure...  So...)

So... I'm obviously having my own kf5/plasma5 problems and can't yet 
really help others with there's much, yet. =:^(
