+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
+```
