Linux performance overlay MangoHud 0.8.0-rc1 out now for testing with Intel GPU support and lots of improvements

MangoHud is a performance overlay you can use on Desktop Linux, and it's what powers the built-in overlay on Steam Deck. A new release candidate is now available for testing for an upcoming stable release with version 0.8.0-rc1.

This release adds a few more applications to the blacklist to stop it appearing and causing issues with them including the Ubisoft Store (UplayWebCore.exe), halloy (IRC client) and Plutonium Launcher (plutonium.exe, plutonium-launcher-win32.exe).

If you like my simple horizontal layout you can find it on GitHub. Just pop it into "~/.config/MangoHud/MangoHud.conf".

Also some fixes made it in including:

• read_cfg didn't properly overwrite config options.
• logging would sometimes crash if it returned an empty vec.
• fix double-logging of avg fps.
• nvidia: warn if both nvml and xnvctrl are unavailable.
• mangoapp didn't properly respond to hide/show hud.
• add 32bit xkbcommon to project dependencies.
• add missing dependencies for opensuse.
• proper vsync implementation.
• refactor FPS calculation in metrics.
• fix exec, network, gpu and vram displaying incorrectly in horizontal mode.

Various other changes:

Changes

• Multiple GPUs can be displayed
• Changed logger errors to debug
• Added CPU power to logging
• Improved wayland keybinds
• Memory usage has been refactored to be inline with other apps
• DLSYM is enabled by default, MANGOHUD_DLSYM=0 to disable it.
• mangoapp vulkan layer is deleted (it was a testing project and no longer in development)
• OpenGL shim
  • The shim is preloaded first instead of the opengl library
  • it checks to make sure there is an opengl context to hook before loading mangohud
  • this should resolve some crashes. More detailed information here c22ced0
• If using exec and inside steam runtime, launch command using steam-runtime-launch-client
  • If mangohud is used inside flatpak, you need to allow your app to speak on org.freedesktop.Flatpak dbus address.
  • Example if you're using mangohud in steam: flatpak override --user --talk-name=org.freedesktop.Flatpak com.valvesoftware.Steam
• Added Intel GPUs support (integrated and discrete, i915 and xe drivers)
  • Temperature is only available in linux 6.13+
  • Temperature and Power Usage is not available for integrated gpus
  • VRAM and GPU Usage is per-process not per-system (that would require root rights)
• Multiple GPUs support:
  • By default, MangoHud displays all GPUs. To select needed GPUs, you can use gpu_list or pci_dev

Params

• network_color sets the color of the network hud element
• display_server shows if the display server is Xorg, Xwayland or wayland
• gpu_list set the GPUs to display in the hud e.g gpu_list=0,1
• proc_mem and io_read now works properly in gamescope (mangoapp)
