Created attachment 157146 [details] Plasma panel and Desktop management.jpg SUMMARY Under X11 the current release of Plasma 5 shows the connected monitors and screens in reversed order. Physically the monitors connected in the following order to the graphic card (Nvidia 2080 TI): at the first port (reported by the nvidia driver) left monitor at the second port right monitor This order ensures that the screens appear on the sddm logon screen in the right order, so the mouse point moves from left to right and backwards correct between the screens - left screen has its right border at the left border of the right screen. Though the same after login. Monitor and Display settings in systems settings show also the correct order using Identification functionality. Only the management window for managing Panels and Desktop shows the screens and therefore the connected monitor in reversed order. STEPS TO REPRODUCE 1. open system settings - Display setting 2. right click on one of the screens and select Edit panel 3. click on manage screen button at the management menu appearing on the top OBSERVED RESULT The new window showing the connected monitors and screens in reversed order compared to display settings EXPECTED RESULT The new window showing the connected monitors and screens show the same order as the display setting in plasma system setting SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 6.2.2-arch1-1 (64-bit) Graphics Platform: X11 Processors: 16 × AMD Ryzen 7 3700X 8-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 2080 Ti/PCIe/SSE2 Manufacturer: Micro-Star International Co., Ltd.

Can confirm. Basically the window is just showing the primary screen first, then secondary, then tertiary, etc. This order may not necessarily match the physical layout of the screens. Not sure if we can really fix this generically since the screen layout is based on spatial positioning, while this window just shows screens in a linear list (wrapped to a grid). They conceivably could match when all screens are arranged in a horizontal line, but anything beyond that and it won't work. So I don't think there's anything we can do here. Sorry.
