+The Steamify app's menu. On a Steam Machine (or any PC with an AMD or Intel
+graphics card) it offers the full SteamOS conversion, on the left. On a PC with
+an NVIDIA graphics card gamescope's gaming mode shows a corrupted picture, so the
+menu offers **Gaming on NVIDIA** instead (Steam on the desktop, started at login,
+optionally in Big Picture), on the right.
