Blackscreen at boot: 5070Ti and F43 KDE

Greetings-
I am still newish to Linux and while I am technically inclined, I am not a programmer.

I installed Fedora 43 KDE on my system. To boot successfully, I have to plug in my monitor using the iGPU. Once that is successful, I can switch to my dedicated GPU and use the system without any problems. Whatever I do, I cannot find an adequate fix for the boot-up. Here are the system details:

  • Operating System: Fedora Linux 43
  • KDE Plasma Version: 6.6.3
  • KDE Frameworks Version: 6.24.0
  • Qt Version: 6.10.2
  • Kernel Version: 6.19.8-200.fc43.x86_64 (64-bit)
  • Graphics Platform: Wayland
  • Processors: 28 × Intel® Core™ i7-14700K
  • Memory: 64 GiB of RAM (62.5 GiB usable)
  • Graphics Processor 1: NVIDIA GeForce RTX 5070 Ti
  • Graphics Processor 2: Intel® Graphics
  • Manufacturer: System76
  • Product Name: Thelio Mira
  • System Version: thelio-mira-b4.1

Here are the details from nvidea-smi:

  • NVIDIA-SMI 580.126.18
  • Driver Version: 580.126.18
  • CUDA Version: 13.0

This is really frustrating and it was not something I encountered when distro-hopping through Ubuntu, Zorin, Pop!_Os, or Bazzite. Of all the distros I have tried, I like Feodra KDE the best and I want to get this working properly.

Nvidia gpus needs extra steps to get working and keep working, they do not work well out-of-the-box as there are no full feature open source drivers in the linux kernel.

Have you installed the rpmfusion nvidia drivers?
Have the nvidia driver successfully built on you system?

You may be able to see log messages if you type ESC on the black screen.
You may be able to get to a text console by typing ctrl-alt-f3.

I would think yes, since OP gets output from nvidia-smi showing the expected driver versions.

It sounds kind of similar to this thread (with an AMD iGPU / Nvidia dGPU system) where the solution was to remove the AMD drivers from initramfs so that both drivers initialised at the same time:

However I don’t know enough to say whether the same approach applies with an Intel iGPU.

is the root drive encrypted? Try booting with plymouth.use-simpledrm

I am happy to try but I do not know how. Is this something I edit in GRUB?
