Do you experience any functional problem, or is this just about the noise in
your journal?

(In the latter case, you can disable the logging output in your
~/.config/QtProject/qtlogging.ini

It seems that the wrong backend is picked, do you have the KSCREEN_BACKEND env
var set?

In any case, you're running an old version of Plasma, which we don't maintain
anymore. I'd advise to upgrade to Plasma 5.7.

In reply to Sebastian Kügler from comment #4) > Could you be more precise?

Yes, running plymouth login screen. Timing starts after hitting enter after passwd. I get a quick x11 X cursor then the little circle indicating working, ~20 seconds latter KDE splash screen.

 OK, ran it down, I needed the command line app for dumping that for my bug_report script.

$ kf5-config --version
 Qt: 5.6.1
 KDE Frameworks: 5.23.0
 kf5-config: 1.0

 Wow, setting KSCREEN_BACKEND=xrandr jumped me right to the KDE splash screen. Good news, all my autostart scripts ran. 

Bad news, No plasma desktop, just a black screen, no taskbar, no desktop shortcuts, no Alt+Space bar,..... 

Just checked, and desktop and whatnot showed up while writing this message. Going to move https://bugs.mageia.org/show_bug.cgi?id=17658 from kscreen to xrandr. 

Thank you for your time and patience.

Well, that's convenient... So basically as a stable distro we're on our own, since upstream considers Plasma 5.6.5 unmaintained two weeks after it's released...

It do make the developer's job much easier.  :(

 Can not find any plasma version information in kinfocenter. See kinfocenter screen shot attachment.

 Quick launch of kde splash screen in comment 5, was a leftover/not dead yet process from previous login. :( 

Guessing this will help 

$ plasmashell --version plasmashell 5.6.5

A little happy that QA seems to like the idea of using the newer KDE release.
Still guessing xrandr will be scrape goat for slow kde login.

Slow Plymouth login is not going to help general public acceptance either.
I added splash back to kernel boot but plymouth login screen is still slow, bug 17530 and bug 17521

My, my, aren't we in a bit of a hurry. :)
I've been working since 1am testing my bug reports.

Since you are in such a hurry, I'll close this because 
  journalctl | grep -i kscreen | grep Error
does not return  Error 145
