Installation - Build From Source

If you wish to compile MangoHud to keep up to date with any changes - first clone this repository and cd into it:

git clone --recurse-submodules https://github.com/flightlessmango/MangoHud.git
cd MangoHud

Using meson to install "manually":

meson build
ninja -C build install

By default, meson should install MangoHud to /usr/local. Specify install prefix with --prefix=/usr if desired. Add -Dappend_libdir_mangohud=false option to meson to not append mangohud to libdir if desired (e.g. /usr/local/lib/mangohud).

To install 32-bit build on 64-bit distro, specify proper libdir: lib32 for Arch, lib/i386-linux-gnu on Debian-based distros. RPM-based distros usually install 32-bit libraries to /usr/lib and 64-bit to /usr/lib64. You may have to change PKG_CONFIG_PATH to point to correct folders for your distro.

CC="gcc -m32" \
CXX="g++ -m32" \
PKG_CONFIG_PATH="/usr/lib32/pkgconfig:/usr/lib/i386-linux-gnu/pkgconfig:/usr/lib/pkgconfig" \
meson build32 --libdir lib32
ninja -C build32 install

Dependencies

Install necessary development packages.

• gcc, g++
• or gcc-multilib, g++-multilib for 32-bit support
• meson >=0.54
• ninja (ninja-build)
• glslang
• libGL/libEGL (libglvnd, mesa-common-dev, mesa-libGL-devel etc)
• X11 (libx11-dev)
• XNVCtrl (libxnvctrl-dev), optional, use -Dwith_xnvctrl=disabled option with meson to disable
• D-Bus (libdbus-1-dev), optional, use -Dwith_dbus=disabled option with meson to disable
• wayland-client
• xcbcommon

Python 3 libraries:

• Mako (python3-mako or install with pip)

If distro's packaged meson is too old and gives build errors, install newer version with pip (python3-pip).

Meson options

Building with build script

You can also use build.sh script to do some things automatically like install dependencies, if distro is supported but it usually assumes you are running on x86_64 architecture.

To just build it, execute:

./build.sh build

You can also pass arguments to meson:

./build.sh build -Dwith_xnvctrl=disabled

Resulting files will be install to ./build/release folder.

If you have compiled MangoHud from source, to install it, execute:

./build.sh install

You can then subsequently uninstall MangoHud via the following command

./build.sh uninstall

To tar up the resulting binaries into a package and create a release tar with installer script, execute:

./build.sh package release

or combine the commands, although package should also call build if it doesn't find the built libs:

./build.sh build package release

If you have built MangoHud before and suddenly it fails, you can try cleaning the build folder, execute:

./build.sh clean

Currently it just does rm -fr build and clears subprojects.

NOTE: If you are running an Ubuntu-based, Arch-based, Fedora-based, or openSUSE-based distro, the build script will automatically detect and prompt you to install missing build dependencies. If you run into any issues with this please report them!

Installation - Pre-packaged Binaries

GitHub releases

If you do not wish to compile anything, simply download the file under Releases, extract it, and from within the extracted folder in terminal, execute:

./mangohud-setup.sh install

Arch-based distributions

If you are using an Arch-based distribution, install mangohud and lib32-mangohud from the extra/multilib repository. mangohud-git and lib32-mangohud-git are available on the AUR to be installed via your favourite AUR helper. These can help fix issues with the hud not activating when using stable releases from pacman!

If you are building it by yourself, you need to enable multilib repository, by editing pacman config:

sudo nano /etc/pacman.conf

and uncomment:

#[multilib]
#Include = /etc/pacman.d/mirrorlist

then save the file and execute:

sudo pacman -Syy

Debian, Ubuntu

If you are using Debian 11 (Bullseye) or later, Ubuntu 21.10 (Impish) or later, or distro derived from them, to install the MangoHud package, execute:

sudo apt install mangohud

Optionally, if you also need MangoHud for 32-bit applications, execute:

sudo apt install mangohud:i386

Fedora

If you are using Fedora, to install the MangoHud package, execute:

sudo dnf install mangohud

Solus

If you are using Solus, to install MangoHud simply execute:

sudo eopkg it mangohud

openSUSE

If you run openSUSE Leap or Tumbleweed you can get Mangohud from the official repositories. There are two packages, mangohud for 64bit and mangohud-32bit for 32bit application support. To have Mangohud working for both 32bit and 64bit applications you need to install both packages even on a 64bit operating system.

sudo zypper in mangohud mangohud-32bit

Leap doesn't seem to have the 32bit package.

Leap 15.2

sudo zypper addrepo -f https://download.opensuse.org/repositories/games:tools/openSUSE_Leap_15.2/games:tools.repo
sudo zypper install mangohud

Leap 15.3

sudo zypper addrepo -f https://download.opensuse.org/repositories/games:tools/openSUSE_Leap_15.3/games:tools.repo
sudo zypper install mangohud

Flatpak

If you are using Flatpaks, you will have to add the Flathub repository for your specific distribution, and then, to install it, execute:

For flatpak:

flatpak install org.freedesktop.Platform.VulkanLayer.MangoHud

To enable MangoHud for all Steam games:

flatpak override --user --env=MANGOHUD=1 com.valvesoftware.Steam

Normal usage

To enable the MangoHud overlay layer for Vulkan and OpenGL, run :

mangohud /path/to/app

For Lutris games, go to the System options in Lutris (make sure that advanced options are enabled) and add this to the Command prefix setting:

mangohud

For Steam games, you can add this as a launch option:

mangohud %command%

Or alternatively, add MANGOHUD=1 to your shell profile (Vulkan only).

OpenGL

OpenGL games may also need dlsym hooking. Add --dlsym to your command like mangohud --dlsym %command% for Steam.

Some Linux native OpenGL games overrides LD_PRELOAD and stops MangoHud from working. You can sometimes fix this by editing LD_PRELOAD in the start script LD_PRELOAD=/path/to/mangohud/lib/

gamescope

To enable mangohud with gamescope you need to install mangoapp. gamescope --mangoapp %command%

Using normal mangohud with gamescope is not supported.

Hud configuration

MangoHud comes with a config file which can be used to set configuration options globally or per application. Usually it is installed as /usr/share/doc/mangohud/MangoHud.conf.example or get a copy from here.

The priorities of different config files are:

1. /path/to/application/dir/MangoHud.conf
2. Per-application configuration in ~/.config/MangoHud:
   1. ~/.config/MangoHud/<application_name>.conf for native applications, where <application_name> is the case sensitive name of the executable
   2. ~/.config/MangoHud/wine-<application_name>.conf for wine/proton apps, where <application_name> is the case sensitive name of the executable without the .exe ending
3. ~/.config/MangoHud/MangoHud.conf

Example: For Overwatch, this would be wine-Overwatch.conf (even though the executable you run from Lutris is Battle.net.exe, the actual game executable name is Overwatch.exe).

If you start the game from the terminal with MangoHud enabled (for example by starting Lutris from the terminal), MangoHud will print the config file names it is looking for.

You can find an example config in /usr/share/doc/mangohud

GOverlay is a GUI application that can be used to manage the config

Environment Variables

You can also customize the hud by using the MANGOHUD_CONFIG environment variable while separating different options with a comma. This takes priority over any config file.

You can also specify configuration file with MANGOHUD_CONFIGFILE=/path/to/config for applications whose names are hard to guess (java, python etc).

You can also specify presets file with MANGOHUD_PRESETSFILE=/path/to/config. This is especially useful when running mangohud in a sandbox such as flatpak.

A partial list of parameters are below. See the config file for a complete list. Parameters that are enabled by default have to be explicitly disabled. These (currently) are fps, frame_timing, cpu_stats (cpu load), gpu_stats (gpu load), and each can be disabled by setting the corresponding variable to 0 (e.g., fps=0).

Example: MANGOHUD_CONFIG=cpu_temp,gpu_temp,position=top-right,height=500,font_size=32 Because comma is also used as option delimiter and needs to be escaped for values with a backslash, you can use + like MANGOHUD_CONFIG=fps_limit=60+30+0 instead.

Note: Width and Height are set automatically based on the font_size, but can be overridden.

Note: RAPL is currently used for Intel CPUs to show power draw with cpu_power which may be unreadable for non-root users due to vulnerability. The corresponding energy_uj file has to be readable by corresponding user, e.g. by running chmod o+r /sys/class/powercap/intel-rapl\:0/energy_uj as root, else the power shown will be 0 W, though having the file readable may potentially be a security vulnerability persisting until system reboots.

Note: The zenpower3 or zenergy kernel driver must be installed to show the power draw of Ryzen CPUs.

Vsync

OpenGL Vsync

• -1 = Adaptive sync
• 0 = Off
• 1 = On
• n = Sync to refresh rate / n.

Vulkan Vsync

• 0 = Adaptive VSync (FIFO_RELAXED_KHR)
• 1 = Off (IMMEDIATE_KHR)
• 2 = Mailbox (VSync with uncapped FPS) (MAILBOX_KHR)
• 3 = On (FIFO_KHR)

Not all vulkan vsync options may be supported on your device, you can check what your device supports here vulkan.gpuinfo.org

Keybindings

• Shift_L+F2 : Toggle Logging
• Shift_L+F4 : Reload Config
• Shift_R+F12 : Toggle Hud

Workarounds

Options starting with "gl_*" are for OpenGL.

• gl_size_query = viewport : Specify what to use for getting display size. Options are "viewport", "scissorbox" or disabled. Defaults to using glXQueryDrawable.
• gl_bind_framebuffer = 0..N : (Re)bind given framebuffer before MangoHud gets drawn. Helps with Crusader Kings III.
• gl_dont_flip = 1 : Don't swap origin if using GL_UPPER_LEFT. Helps with Ryujinx.

FPS logging

You must set a valid path for output_folder in your configuration to store logs in.

When you toggle logging (default keybind is Shift_L+F2), a file is created with the game name plus a date & timestamp in your output_folder.

Log files can be visualized with two different tools: online and locally.

Online visualization: FlightlessMango.com

Log files can be (batch) uploaded to FlightlessMango.com, which will then take care of creating a frametime graph and a summary with 1% min / average framerate / 97th percentile in a table form and a horizontal bar chart form.

Notes:

• Uploaded benchmarks are public: you can share them with anyone by simply giving them the link.
• Benchmark filenames are used as legend in the produced tables and graphs, they can be renamed after the upload.

Local visualization: mangoplot

mangoplot is a plotting script that is shipped with MangoHud: on a given folder, it takes each log file, makes a 1D heatmap of its framerates, then stacks the heats maps vertically to form a 2D graph for easy visual comparison between benchmarks.

Example output:

_{^{Overwatch 2, 5950X + 5700XT, low graphics preset, FHD, 50% render scale}}
