cd MangoHud

Then simply run the following commands:

./build.sh build

sudo ./build.sh install

If you are running an Ubuntu-like distribution, Fedora, or Arch, 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!

Fedora: sudo dnf install mangohud

Arch: Install mangohud and lib32-mangohud with your favourite AUR helper. mangohud-git is also available on the AUR.

Normal usage

To enable the MangoHud Vulkan overlay layer, run :

MANGOHUD=1 /path/to/my_vulkan_app

Or alternatively, add MANGOHUD=1 to your shell profile.

Hud configuration

MangoHud comes with a config file which can be used to set configuration options globally or per application. The priorities of different config files are:

/path/to/application/dir/MangoHud.conf
$HOME/.config/MangoHud/{application_name}.conf
$HOME/.config/MangoHud/MangoHud.conf
$HOME/.local/share/MangoHud/MangoHud.conf

The default config file is installed to $HOME/.config/MangoHud/MangoHud.conf and will not be overwritten by the script.

`MANGOHUD_CONFIG` environment variable

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.

A partial list of parameters are below. See the config file for a complete list.

Variable	Description
`cpu_temp` `gpu_temp`	Displays current CPU/GPU temperature
`core_load`	Displays load & frequency per core
`ram` `vram`	Displays system RAM/VRAM usage
`full`	Enables all of the above config options
`crosshair`	Adds a crosshair overlay at the centre of the screen
`font_size=`	Customizeable font size (default=24)
`width=` `height=`	Customizeable hud dimensions (in pixels)
`position=`	Location of the hud: `top-left` (default), `top-right`, `bottom-left`, `bottom-right`
`no_display`	Hide the hud by default
`toggle_hud=` `toggle_logging=`	Modifiable toggle hotkeys. Default are F12 and F2, respectively.
`time` `time_format=%T`	Displays local time. See std::put_time for formatting help.
`gpu_color` `gpu_color` `vram_color` `ram_color` `io_color` `engine_color` `frametime_color` `background_color` `text_color`	Change default colors: `gpu_color=RRGGBB`
`alpha`	Set the opacity of all text and frametime graph `0.0-1.0`
`background_alpha`	Set the opacity of the background `0.0-1.0`

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

Example: MANGOHUD_CONFIG=cpu_temp,gpu_temp,position=top-right,height=500,font_size=32

Environment Variables

MANGOHUD_OUTPUT : Define name and location of the output file (Required for logging)
MANGOHUD_FONT: Change default font (set location to .TTF/.OTF file )
