I typically use Neon with X11 as I have a Nvidia GeForce RTX 4060 graphic card and have had issues using the Nvidia 550 driver with Wayland.
I occassionally switch back to Wayland for testing purposes and did so today. I logged out of X11 and selected Wayland from the memu. The system crashed and I was left with a blank screen. I did a hard re-boot and tried again - with the same results.
The system logs showed ‘org_kde_powerdevil’ errors at the time of starting the kde plasma with wayland
Many thanks
