Hi,

My problem with drm.
In dmesg appear one error with drm.

dmesg -l err

I’m not sure what exactly what the issue is, sorry to be a bit annoying in this next sentence: there was no clear question asked or issue presented.

Though, from looking quickly, it looks like you may be having issues starting the graphical environment.

If so, I have hopes the issue might be resolved in a newer kernel. NixOS defaults to using the latest stable LTS kernel, but sometimes for relatively or really new hardware, it causes issues. Seeing it’s an ix-7xxx series CPU makes me think it could help.

To use the latest kernel, add this to your configuration.nix.

{/*...*/}:
{
  # [...]
  # Use the latest kernel for better hardware support.
  boot.kernelPackages = pkgs.linuxPackages_latest;
  # [...]
}
