Bug ID: 475653
Summary: Primary monitor is switched when coming back from
suspend/rebooting
Classification: Plasma
Product: kwin
Version: 5.27.8
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: multi-screen
Assignee: kwin-bugs-n...@kde.org
Reporter: ja...@jamesnorth.net
Target Milestone: ---
SUMMARY
I have two monitors. I set one of the monitors as the primary display, but when
the computer wakes up again, the monitor is switched (often, I'm not sure if
this is always the case). I then need to set the other monitor back to primary
and the taskbar will move back.
I experienced this issue on Fedora, but recently moved to Arch Linux and am
still facing this issue. I have a NVIDIA card, and am running Wayland.
My second monitor uses a HDMI port but is converted to DisplayPort before being
plugged into my GPU. My monitor uses HDMI.
There is nothing in my ~/.config/plasmashellrc related to Screen Connectors.
This command produces no output: grep -A4 tors ~/.config/plasmashellrc
