Bug ID: 454604
Summary: Display scale "lost" when plugging/unplugging external
monitor
Product: kwin
Version: 5.24.90
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Sometimes (I can reproduce with an external HDMI TV, but not with a monitor
connected to a USB-C docking station) the scale factor from the Display
Configuration, is not respected after connecting (and/or disconnecting) an
external display.
Setting is not modified. Rebooting does not solve the issue. Only modifying the
value to a different one, saving, and then going back to the desired value
restores the settings.
P.S. Thank you for the great work doing for this and previous releases. I have
now changed to Wayland and it feels great!
STEPS TO REPRODUCE
1. Configure some scale (e.g. 125%)
2. Connect an external monitor (and use the extend mode)
3. Remove external monitor
OBSERVED RESULT
Scale value still shows 125% but it is in fact back to 100%. Rebooting does not
solve the issue. Configuration still shows a scale of 125% but in reality is
100%. To go back to 125%, you can change to 150% save, and then go back to
125%.
EXPECTED RESULT
Scale factor should always be respected for the built-in screen and not changed
no matter if an external display is attached. Also, in any case, detaching the
external display, should restore previous state.
