--- Comment #2 from [email protected] --- Nvidia specs and dynamics: The issue occurs under a stable system configuration with NVIDIA Proprietary Driver version 580.95.05, configured to prevent the creation of the legacy VESA framebuffer device. This configuration relies specifically on the nvidia-drm kernel module. Driver in Use: NVIDIA Proprietary Driver Version: 580.95.05; Configuration Parameter: the kernel parameter nvidia-drm.fbdev=0 is used; Resulting System State: the primary DRM device, /dev/dri/card0, is non-existent. The sole active GPU is correctly registered as /dev/dri/card1. KWin Failure (Core Bug): KWin (kwin_wayland) fails to initialize because its enumeration logic rigidly expects and fails on the missing /dev/dri/card0, instead of gracefully falling back and initializing with the available and correct /dev/dri/card1. Conclusion based on analysis: the KWin DRM backend logic should be reviewed to correctly handle the ENOENT error when probing a non-existent /dev/dri/card0 and continue the probe with the next available device (i.e., /dev/dri/card1). -- You are receiving this mail because: You are watching all bug changes.
