+I use Nix mainly with home manager on my Ubuntu laptop, and for the most part, it works fine. However, some apps installed
+using Nix, need to use [nixGL](https://github.com/nix-community/nixGL). A wrapper tool for OpenGL, allowing Nix installed
+tooling to use the system's OpenGL and Vulkan APIs. Some apps including kitty and Firefox (mainly for Google Meet).
+
+There is currently a [branch](https://github.com/nix-community/home-manager/pull/5355) in home-manager we can pull
+into our config, which provides a convenient way to wrap these apps in nixGL rather than needing to specify say
+`nixGLIntel kitty` in our terminal or say Hyprland config (key bindings).
+
+First, let's import the relevant code from the branch/PR:
+
+```nix
+ imports = [
+    # TODO: remove when https://github.com/nix-community/home-manager/pull/5355 gets merged:
+    (builtins.fetchurl {
+      url = "https://raw.githubusercontent.com/Smona/home-manager/nixgl-compat/modules/misc/nixgl.nix";
+      sha256 = "01dkfr9wq3ib5hlyq9zq662mp0jl42fw3f6gd2qgdf8l8ia78j7i";
+    })
+  ];
+```
+
+Then, simply, we can do something like this:
+
+
+```nix
+programs = {
+    kitty.package = config.lib.nixGL.wrap pkgs.kitty;
+    firefox.package = config.lib.nixGL.wrap pkgs.firefox;
+}
+```
+
+Then we should be able to use the apps like normal, such as using our app launcher like rofi.
+That's It!
