test procedure

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.

> Do you experience any functional problem,
Taking 30+ seconds to get a usable desktop.

> It seems that the wrong backend is picked, do you have the KSCREEN_BACKEND env var set?
No.

What command would I use to get the current Plasma version?

Could you be more precise? Does it take 30 seconds to log in, to apply changes, or ... ?

kinfocenter shows the current Plasma version.

It seems that the wrong backend is picked by kscreen for whatever reason. You could try exporting KSCREEN_BACKEND=xrandr to force the correct backend (xrandr 1.1 is deprecated, your X actually provides xrandr 1.5, but the xrandr 1.1 backends doesn't understand it.

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.

That's not the Plasma version, but the Frameworks version. As I said, please run kinfocenter to find out.

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

 get_src_rpm /usr/bin/kinfocenter

      Installed rpm : kinfocenter-5.6.5-1.mga6
      Source rpm    : kinfocenter-5.6.5-1.mga6.src.rpm

Apparently, your distro changes the session file for plasma.desktop. Please find out the version in your distro.

Please upgrade to Plasma 5.7 and show me the output of kscreen-doctor -b

You might need to give me specific file name when possible. I am just a dumb user here. Guessing

$ get_src_rpm /usr/share/xsessions/01plasma.desktop

Ok, Mageia developers have upgraded.
$ plasmashell --version
plasmashell 5.7.0

FYI: kinfocenter does not show plasma version.
$ get_src_rpm /usr/bin/kinfocenter

$  kscreen-doctor -b

kscreen.xcb.helper: Event Error: 145 still occurs

set  export KSCREEN_BACKEND=KSC_XRandR.so over in /etc/profile.d/mu_custom_env.sh
rebooted, problem no longer shows up in the log.

kde/plasma launch  time still too long.
> (In reply to Sebastian Kügler from comment #4) > Could you be more precise? 

No idea about anyone's boot time but mine is pretty sad even after converting to
systemd networking knocking off ~40 seconds.

1. 40.62 seconds from grub2 launch to Plymouth login screen.
2. 35.42 seconds from pw enter to kde splash screen
3. 57.78 seconds until operational Plasma desktop.

1 and 3 gives me about 1 minute 38.40 seconds "boot" time.
with about 22.36 seconds Plasma time.

Is there somewhere other than user shell environment script that aught to  set KSCREEN_BACKEND ?
