545 won’t boot into Wayland/KDE for me either. Black screen, monitors idle. No video output. Xorg is the only thing that works.
I’ve tried all these supposed fixes adding things nvidia-drm did nothing. fbdev=1 actually caused the system to not boot at all. Wouldn’t make it passed bootloader.
Whether or not Wayland works at all with Nvidia seems like a diceroll. I’ve done countless hours of research and it really seems like for some folks it just doesn’t work. Nobody can pinpoint why yet.
I was able to get going with kubuntu pretty easy.
Kubuntu. Pop os or nobara seem to be the popular ones for new people. Not that they’re particularly special. They just have a lot of things pre installed. Which saves some hassle.
With all that said. BACK UP YOUR WINDOWS INSTALL.
