I was unable to get the hybrid settings working well with lightdm or sddm, but Optimus Sync mode seems to work the best for me. I am running the Linux 6.6 LTS kernel with KDE + SDDM, and it seems to be working well. ## hardware-configuration.nix I have the following customizations added for my nvidia drivers. ``` hardware.nvidia = { nvidiaSettings = true; package = config.boot.kernelPackages.nvidiaPackages.stable; }; ``` ## Setup at the time of testing ### nix-info ``` $ nix-info -m - system: `"x86_64-linux"` - host os: `Linux 6.6.8, NixOS, 23.11 (Tapir), 23.11.20231231.32f6357` - multi-user?: `yes` - sandbox: `yes` - version: `nix-env (Nix) 2.18.1` - nixpkgs: `/nix/var/nix/profiles/per-user/root/channels/nixos` ``` ### lspci ``` $ lspci ... 01:00.0 VGA compatible controller: NVIDIA Corporation AD107M [GeForce RTX 4060 Max-Q / Mobile] (rev a1) ... 05:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
