Bug ID: 483568 Summary: Cannot enable multiple screens at once on Wayland Classification: Plasma Product: kwin Version: 6.0.2 Platform: Arch Linux OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: multi-screen Assignee: kwin-bugs-n...@kde.org Reporter: p...@ul-kupper.de Target Milestone: --- Created attachment 167178 --> https://bugs.kde.org/attachment.cgi?id=167178&action=edit Attempt to enable a second screen is not working SUMMARY Since the update from Plasma 5.91.0 to Plasma 6.0.1 and also in Plasma 6.0.2, I have been unable to enable more than one screen at a time in the Wayland session. STEPS TO REPRODUCE 1. See attached screen capture OBSERVED RESULT Any attempt to enable a second display does not have any effect (both in the Settings GUI as well as when using kscreen-doctor) I am able to enable each display individually by disabling the previously active display first. Kscreen doctor command for intended screen setup (running this has no effect): kscreen-doctor \ output.1.disable \ output.2.enable \ output.2.mode.0 \ output.2.scale.1 \ output.2.position.0,360 \ output.3.enable \ output.3.mode.0 \ output.3.scale.1.50 \ output.3.position.1920,0 \ EXPECTED RESULT Previously, I was able to enable an arbitrary combination of displays with mixed resolutions, scale factors and refresh rates in the Wayland session. SOFTWARE/OS VERSIONS Linux: linux 6.6.21-1-lts kernel KDE Plasma Version: 6.0.2 ADDITIONAL INFORMATION Display Setup: Internal Laptop Display (1440p) + 2 external displays (1080p & 4K) attached via Thunderbolt 4 Dock.
