Package: kwin-wayland Severity: normal Hello,
I am experiencing a persistent 2-minute boot delay and black screen / hang during the transition to the desktop session on Debian 13 (Trixie) running KDE Plasma with Wayland. Hardware Configuration: - CPU/GPU 1: AMD Raphael (amdgpu) - GPU 2: Intel Arc B580 (xe driver) - Display Server: Wayland / SDDM Symptoms: During boot, the system hangs for over 2 minutes right before the graphical session initializes. KWin logs indicate DRM synchronization failures and OpenGL initialization timeouts due to contention between the xe and amdgpu DRM devices. Forcing the initramfs to load both modules (xe, amdgpu) early mitigates the initial module load, but session initialization still suffers from severe time-outs under Wayland/KWin unless forced to X11. Could you please advise or investigate how to properly handle device priority and DRM synchronization for hybrid xe + amdgpu setups in Plasma Wayland?
