Description Fabio 2019-08-27 05:34:29 UTC

SUMMARY
The scale factor used is the last scale factor set via System Settings, regardless of which monitor is connected.

STEPS
1. Connect a second display.
2. Set the scale factor to 1 for the main display
2. Set the scale factor to 2 for the second display
3. Boot the system with only the first display connected

OBSERVED RESULT
The GUI is rendered with scale factor 2

EXPECTED RESULT
The GUI is rendered with scale factor 1

ADDITIONAL INFORMATION
The current scale factor and the displays scale factor are correctly saved in .config/kdeglobals under the [KScreen] section.

Are you on Wayland?

Comment 2 Fabio 2019-08-27 14:45:54 UTC

No, I am on X11

Comment 3 Nate Graham 2022-11-08 21:38:12 UTC

Then this is expected, because X11 doesn't have per-display scale factors. That's a Wayland-only feature, as unfortunately Wayland provides the only practical way to make it work properly.
