Plasma6 with AMD: black screen with mouse

Help
1

Since the update to Plasma6, when I login to my plasma session, I have a black screen with only the mouse displayed. I found some similar topics but they are related to NVIDIA while I use an AMD GPU.

The content of journalctl -xb can be found here.

From my hardware-configuration.nix:

  boot.initrd.availableKernelModules = [ "nvme" "xhci_pci" "usb_storage" "sd_mod" "rtsx_pci_sdmmc" ];
  boot.initrd.kernelModules = [ "amdgpu" ];
  boot.kernelModules = [ "kvm-amd" ];
  boot.extraModulePackages = [ ];
  hardware.cpu.amd.updateMicrocode = lib.mkDefault config.hardware.enableRedistributableFirmware;

If any further information are needed to find what is wrong, please tell me.

Did you manage to solve this?
I’m having the same issue on an AMD laptop with integrated graphics.

have you tried removing boot.initrd.kernelModules = [ "amdgpu" ];?
I have to do this when I upgrade from 24.11 to 25.05, do not know why.

I finally solved it, the second answer here helped
I just removed the plasma-org.kde.plasma.desktop-appletsrc file and logged out and back in.

No, I gave up and set up a dual boot with Arch Linux. I boot into NixOS from time to time to update it, but nothing changes. I also have issues with SDDM about files not found or something like that.

I didn’t try to remove this option since I added it in an attempt to solve the problem.

I created a new user with empty profile without result.
