I started experiencing these issues after using `sudo nvautoinstall primec`.

Output of `sudo nvautoinstall compat`: ``` [ # ] NVIDIA AUTOINSTALLER FOR FEDORA LINUX [ ★ ] CHECKING FOR GPU COMPATIBILITY... [ ! ] Compatibility infomation was obtained [ ✓...

Reverting the NVIDIA driver install with the RPMfusion guide fixed the SDDM and applications.

I have tried to reinstall just the driver without other things such as FFMPEG and vulkan, however it doesn't boot at all now.

I managed to get it to start after the 4th reboot (??) and Nvidia X-Server settings works now. GreenWithEnvy is also able to get data from the GPU. Applications do...

I have been able to reproduce the same issue (blackscreen SDDM & broken apps) when manually setting the Nvidia GPU as primary GPU with the [fedora docs guide](https://docs.fedoraproject.org/en-US/quick-docs/how-to-set-nvidia-as-primary-gpu-on-optimus-based-laptops/#_why_would_you_want_to_do_that).
