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.

No. > In any case, you're running an old version of Plasma, which we don't maintain anymore. 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.
(In reply to Sebastian Kügler from comment #4) > Could you be more precise? Does it take 30 seconds to log in, 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. > kinfocenter shows the current Plasma version. 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 > 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. 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

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.

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 ?
