Created attachment 185320 [details] kde-wayland-bugreport 📝 Bug report listo para bugs.kde.org Product: KWin Component: Wayland Version: 6.3.6 Platform: Debian 13 (Trixie) – Plasma Wayland session Hardware: AMD Radeon Pro WX5100 (Polaris10), 3× 4K monitors (DP-1, DP-2, DP-3) Summary Wayland session in Plasma 6.3.6 with AMD WX5100 (Polaris) only activates 1 monitor, while amdgpu DRM reports 3 connected. Steps to reproduce: Start Plasma Wayland session on Debian 13 with AMD WX5100. Connect 3 monitors via DisplayPort. Open System Settings → Display Configuration. Expected result: All 3 connected monitors should be visible and configurable (as in Plasma X11 session). Actual result: Only 1 monitor is shown and active. The other 2 remain black / unavailable. In Plasma X11 session, all 3 monitors work fine. Additional information: Plasma: 6.3.6 KDE Frameworks: 6.13.0 Qt: 6.8.2 Mesa: 25.0.7 Kernel: 6.12.48 GPU: AMD Radeon Pro WX5100 (Polaris10) Driver: amdgpu (radeonsi, RADV) DRM (modetest -c) shows 3 connectors connected with valid EDID. cat /sys/class/drm/*/status shows 3× connected. Bug only happens on Wayland; X11 session works with 3 monitors. Attachments: Output of modetest -c Output of cat /sys/class/drm/*/status Relevant journal logs (journalctl --user -b | grep kwin)
