Bug ID: 471640 Summary: Lost ability to tile 3 displays when "for only this specific display arrangement" is selected Classification: Plasma Product: KScreen Version: 5.27.6 Platform: Fedora RPMs OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: common Assignee: kscreen-bugs-n...@kde.org Reporter: arca...@ivanov.biz Target Milestone: --- This just happened recently. When selecting "Save displays' properties: for only this specific display arrangement" during applying display configuration the display configuration fails while screens reset and initialize. Moving to "for any display arrangement" is a workaround to make things work. This involves 2 x 4k displays via USB-C dock plus primary laptop screen. STEPS TO REPRODUCE 1. Start with "built-in screen". Select "for only this specific display arrangement" option in screen configuration. 2. Tile the dock's displays around your built-in screen. Click Apply. 3. Observe the flickers of initialization and "New output detected" appearing several times. Observe that flickers stop and only built-in screen is configured with dock's displays gone. 4. Repeated the same procedure (1 - 3) with "for any display arrangement". Observe same flickering etc but all screens configuring normally with all specified displays. OBSERVED RESULT Only built-in screen configured EXPECTED RESULT All 3 screens are configured SOFTWARE/OS VERSIONS Operating System: Fedora Linux 38 KDE Plasma Version: 5.27.6 KDE Frameworks Version: 5.107.0 Qt Version: 5.15.10 Kernel Version: 6.3.8-200.fc38.x86_64 (64-bit) Graphics Platform: X11 Processors: 16 × Intel® Core™ i9-9980HK CPU @ 2.40GHz Memory: 62.4 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 630 Manufacturer: Dell Inc.
