Bug ID: 371196
Summary: Panel consistently appears on wrong monitor after
reboot since 5.8
Product: KScreen
Version: 5.8.2
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: kded
Assignee: se...@kde.org
Reporter: matthewisrip...@gmail.com
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.
