kwin_wayland crashes immediately on every Wayland session login attempt.
The session starts, then immediately crashes, kicking back to the login
screen (plasmalogin). X11 sessions work correctly with no issues.
System info:
- Fedora 44 (kernel 7.1.8-200.fc44.x86_64)
- GPU: NVIDIA GeForce RTX 3050 Laptop GPU
- Nvidia driver: 610.57.04 (xorg-x11-drv-nvidia, RPM Fusion)
- Plasma/KWin version: [run `plasmashell --version` and paste it]
Steps already tried (none resolved the crash):
- nvidia-drm.modeset=1 kernel parameter (confirmed active via /proc/cmdline)
- egl-gbm and egl-wayland packages installed
- akmod-nvidia rebuilt and reinstalled
- Full system reboot after each change
- Reset Plasma configs (~/.config, ~/.cache) to rule out corrupted settings
The crash is 100% reproducible - every single Wayland login attempt fails
identically.
