Steam Deck (SteamOS):
+
+ MangoHud is pre-installed. Enable it per-game by adding
+
+ mangohud %command%
+
+ to the game's Steam launch options (right-click game → Properties → Launch Options).
+
+
+
Other Linux handhelds (ROG Ally, Legion Go):
+
+ Install via package manager:
+
+ sudo apt install mangohud
+
+ or Flatpak:
+
+ flatpak install flathub org.freedesktop.Platform.VulkanLayer.MangoHud
+
+
+
+
Manual build:
+
+ See{" "}
+
+ github.com/flightlessmango/MangoHud
+
+
+
+
Troubleshooting:
+
+ • Log file empty? Check MangoHud is enabled for the game and the config was written.
+
+ • Wrong path? Ensure the plugin can write to /tmp/.
+
+ • Not attaching? Try adding
mangohud %command% to Steam launch options explicitly.
