kscreen-console outputs log
Here is also "kscreen-console outputs" log.
I've mixed up expected and observed results sections, sorry. > wl_outputs order MUST match KScreen's display order
No, they must not. wl_output can be in any order. There's a separate protocol to communicate the output order, but the apps should not it, it's for plasma's internal use.

Created attachment 170806 [details] Screen Priorities SUMMARY I have 3 monitors, with my primary monitor in the middle. I've set screen priorities with the middle monitor as a primary monitor. But KWin doesn't respect this setting and place wl_outputs in arbitrary order (probably how monitors were initialized during boot). This is very annoying since a there's no concept of primary monitor in Wayland and most fullscreen apps (mostly SDL ones) are putting themselves on a first reported wl_output. STEPS TO REPRODUCE 1. Log into system (either with autologin or SDDM) 2. Look at the KScreen priority settings (attachment) 3. Compare them to wl_outputs order in System Info Wayland section (additional info) OBSERVED RESULT wl_outputs order MUST match KScreen's display order (kscreen-console outputs or kscreen-doctor -o) EXPECTED RESULT wl_outputs order differs from KScreen's one, most importantly primary display isn't the first reported wl_output SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.1.0 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.1 Kernel Version: 6.9.5-2-cachyos (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-7700K CPU @ 4.20GHz Memory: 15.6 ГиБ of RAM Graphics Processor: AMD Radeon RX 6700 XT ADDITIONAL INFORMATION interface: 'kde_output_device_v2', version: 8, name: 59 interface: 'kde_output_device_v2', version: 8, name: 60 interface: 'kde_output_device_v2', version: 8, name: 61 interface: 'wl_output', version: 4, name: 62 name: HDMI-A-1 description: Philips Consumer Electronics Company Philips 235PL/DL41103143133 x: 3840, y: 0, scale: 1, physical_width: 510 mm, physical_height: 287 mm, make: 'Philips Consumer Electronics Company', model: 'Philips 235PL/DL41103143133', subpixel_orientation: unknown, output_transform: 90°, mode: width: 1920 px, height: 1080 px, refresh: 60.000 Hz, flags: current interface: 'wl_output', version: 4, name: 63 name: DP-2 description: Philips Consumer Electronics Company Philips 226V4/UK81443014262 x: 0, y: 0, scale: 1, physical_width: 477 mm, physical_height: 268 mm, make: 'Philips Consumer Electronics Company', model: 'Philips 226V4/UK81443014262', subpixel_orientation: unknown, output_transform: normal, mode: width: 1920 px, height: 1080 px, refresh: 60.000 Hz, flags: current interface: 'wl_output', version: 4, name: 64 name: DP-1 description: ASR PG27FF1A/0x00000D42 x: 1920, y: 0, scale: 1, physical_width: 598 mm, physical_height: 336 mm, make: 'ASR', model: 'PG27FF1A/0x00000D42', subpixel_orientation: unknown, output_transform: normal, mode: width: 1920 px, height: 1080 px, refresh: 165.003 Hz, flags: current
