I have a multi-monitor setup consisting of my 144Hz primary monitor in front of me on displayport, and my 60Hz secondary monitor to the right on HDMI. After I upgraded from 5.7.5 to 5.8.1 on Archlinux, my panel consistently appears on my non-primary monitor after rebooting, and the default wallpaper appears on my primary monitor. After going into the system settings and setting my primary display to my HDMI monitor, then back to my DP monitor, my panel and wallpaper move back to my primary monitor. But my secondary monitor then has the default wallpaper and desktop toolbox. In addition, I set the refresh rate of my 144Hz monitor to 120Hz, and this has also been resetting to 144Hz after rebooting. I can set those back to normal, but it's annoying to have to do on each boot. This behaviour didn't occur on 5.7, and I've never experienced multi-monitor issues in the year I've been using plasma 5 (unlike many others), so I consider this a regression. Behaviour similar to this is described in the comments of a few other bug reports (https://bugs.kde.org/show_bug.cgi?id=370180 and https://bugs.kde.org/show_bug.cgi?id=356225, the latter is filled with noise and now closed), but I couldn't find any bug report specifically describing this issue. I waited until 5.8.2 before filing a bug report to see if it would be fixed but the bug still occurs. Also, I apologize if this should have been filed against plasmashell instead of KScreen. Reproducible: Always Steps to Reproduce: 1. Upgrade to Plasma 5.8 2. Configure DP monitor to be primary with panel 3. Reboot Actual Results: Panel appears on secondary (HDMI) monitor and wallpaper of other monitor is reset to default and the desktop toolbox appears in the top right corner. Expected Results: Panel should remain on primary (DP) monitor, and both monitors should keep the same wallpaper. I have an NVIDIA 970 using the proprietary drivers version 370.28. Below are the outputs of `kscreen-console bug` and `qdbus org.kde.KWin /KWin supportInformation`. I noticed that `kscreen-console bug` said "kscreen.log" couldn't be parsed, but after deleting `~/.local/share/kscreen/kscreen.log` and rebooting, the problem still occurred. matt@KaFei:~$ kscreen-console bug START: Requesting Config Received config.

I can confirm this issue. I also waited till 5.8.2 but it wasn't fixed. Wanted to report a bug but looks like it is already reported.
This bug appears fixed on my end in 5.8.4, I rebooted a few times and got my correct monitor configuration every time.
Yeah, I also don't have any problems for quite some time (I was using 5.8.3 with relevant patches backported). I guess let's close this bug.
