SUMMARY STEPS TO REPRODUCE 1. I have connected dual monitor setup, both 4k one via hdmi, secondary via display port 1.4a 2. Botting up computer makes both screens looking as mirror even last session before reboot wath to extend primary monitor - that is issue one, systemsetting doesn't remember last configuration. 3. I have for example shutdown only monitors over night let PC on and when coming back next day, I switch on both monitors, they are again mirrored, but this time when I try to organize their layout to extended mode, I can move them to right positions via systemsettings gui, but when click apply, its just blink and they remain both in mirrored mode. The only thing which resolves this is PC reboot. I even tried to disconnect cables, etc. was playing bit with behavior, but nothing helps. when in state of supporting only mirroring i wasn't able to get extended view anymore. OBSERVED RESULT after some pc usage I cannot setup extended mode anymore without hard reboot. EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Gentoo kernel 5.13.10 (available in About System) KDE Plasma Version: 5.21.5 KDE Frameworks Version: 5.82.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION Operating System: Gentoo Linux KDE Plasma Version: 5.21.5 KDE Frameworks Version: 5.82.0 Qt Version: 5.15.2 Kernel Version: 5.13.10-gentoo-x86_64 OS Type: 64-bit Graphics Platform: X11 Processors: 36 × Intel® Xeon® CPU E5-2697 v4 @ 2.30GHz Memory: 62.3 GiB of RAM Graphics Processor: NVIDIA GeForce GT 1030/PCIe/SSE2
