Package: hhd
Handheld DaemonHandheld Daemon is a project that aims to provide utilities for managing handheld
devices.
Right now, it features a fully functional controller emulator that exposes gyro,
paddles, LEDs and QAM across Steam, Yuzu, Dolphin and others.
It brings all supported devices up to parity with Steam Deck.
Readsupported devicesto see if your device is supported.Handheld Daemon exposes configuration through an API, and there is already a Decky
plugin for it (hhd-decky) and a web
app for it (hhd.dev) that also works locally with Electron
(hhd-ui).In addition, a new TDP plugin (currently non-functional) is in the works, that
will allow both vendor specific and vendor independent TDP controls.

Paddles/extra buttons, RGB remapping, Touchpad, and Gyro support.
The gyro axis might be incorrect for some of those devices, and can be easily
fixed in the configuration menu by followingthese steps.
If you do take the time, please open an issue with the correct mapping so it
is added to your device.Legion GoROG AllyGPD WinWin 4Win MiniWin Max 2 2023AyaneoAir Standard/Plus/Pro1S/1S Limited2/2SGEEK, GEEK 1SNEXT Lite/Pro/AdvanceSLIDEAynLoki MaxAOKZOEA1A1 ProOnexplayerMini ProIn addition, Handheld Daemon will attempt to work on Ayaneo, Ayn, Onexplayer, and
GPD Win devices that have not been verified to work
(controller emulation will be off on first start).
If everything works and you fix the gyro axis for your device, open an issue
so that your device can be added to the supported list.
The touchpad will not work for devices not on the supported list.RGB support is not yet available for GPD Win 4, it is currently being investigated.
In addition, GPD Win 4's touch point acts like a mouse, so it unfortunately can not
be used for steam input.
Some devices do not support holding the power button to open steam settings on
the current version, this will be fixed in a future release.Installation InstructionsYou can install the latest stable version ofhhdfrom PyPi (recommended), AUR,
or COPR.
The easiest way to use Handheld Daemon is to install Bazzite which
comes pre-installed with the latest version and all required kernel
fixes for supported devices, seehere.
Nobara also packages hhd and it will become the default for supported devices soon.
However, it only packages fixes for the Ally and Legion Go at the time of this
writing.[!IMPORTANT]
To ensure the gyro of the Legion Go with AMD SFH runs smoothly,
a udev rule is included that disables the use of the accelerometer by the
system (e.g., iio-sensor-proxy).
If you want display auto rotation to work, see manual local steps.Automatic Local InstallYou can use the following bash scripts to install and uninstall Handheld Daemon.
Then, update from Decky or the UI.
These steps do not work on Bazzite, seehere.If your distro uses HandyGCCS/Handycon to fix certain key bindings by default
you need to uninstall it. Disabling it is not enough, since it is autostarted
by certain sessions (such asgamescope-session-plus).
This includes both ChimeraOS and Nobara (seeCommon Issues after Install).# Installcurl-Lhttps://github.com/hhd-dev/hhd/raw/master/install.sh|sh# Uninstallcurl-Lhttps://github.com/hhd-dev/hhd/raw/master/uninstall.sh|shYou can also install the Decky plugin.
Having Decky installed is a prerequisite (instructions).curl-Lhttps://github.com/hhd-dev/hhd-decky/raw/main/install.sh|shThen, reboot and go tohhd.devto configure or read more in
theconfiguration section.Before creating an issue, make sure you are using the latest Handheld Daemon
version and that you read the extra information for each setting in
eitherhhd.devor thestate.ymlfile.The context is required to understand what each setting does and is
not included in the current version of the Decky Plugin
due to UI limitations.Using an older versionIf you find any issues with the latest version of Handheld Daemon
you can use any version by specifying it with the command below.sudosystemctlstophhd_local@$(whoami)~/.local/share/hhd/venv/bin/pipinstallhhd==1.0.6
sudosystemctlstarthhd_local@$(whoami)Manual Local InstallationYou can also install Handheld Daemon using a local package, which enables auto-updating.
These are the same steps as done in the Automatic Install (also seeCommon Issues after Install).
These steps do not work on Bazzite, seehere.# !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!# !!!!

does not wake up after sleep so Handheld Daemon stops working.
This patch is included with Linux kernel 6.7.Seeherefor the required kernel patches.
Without the patch series for the IMU (where patches 0001, and 0002 are included
in kernel 6.8), the gyro will not work.You can hold the ROG Crate button to switch to the ROG Ally's Mouse mode to turn
the right stick into a mouse.Extra steps GPD Win DevicesIn order for the back buttons in GPD Win Devices to work, you need to map the
back buttons to Left: Printscreen, Right: Pause using Windows.
This is the default mapping, so if you never remapped them using Windows you
will not have to.
Handheld Daemon automatically handles the interval to enable being able to hold
the button.Here is how the button settings should look:Left-key: PrtSc + 0ms + NC + 0ms + NC + 0ms + NC
Right-key: Pausc + 0ms + NC + 0ms + NC + 0ms + NCExtra steps for Ayaneo/Ayn/OnexplayerSeeherefor the required kernel patches.
For led support in Ayaneo, you will need theayaneo-platformdriver, and for Ayn, theayn-platform.
Provided these drivers are installed and are supported by your device,
LED support will be enabled by default.The paddles of the Ayn Loki Max are not remappable as far as we know.Extra steps for Legion GoIf you are using a kernel older than 6.8 and you are not on a gaming distro
(ChimeraOS, Nobara, Bazzite), you need the following rule for the controllers
to be recognized.# Enable xpad for the Legion Go controllersATTRS{idVendor}=="17ef",ATTRS{idProduct}=="6182",RUN+="/sbin/modprobe xpad"RUN+="/bin/sh -c 'echo 17ef 6182 > /sys/bus/usb/drivers/xpad/new_id'"If you have set any mappings on Legion Space, they will interfere with Handheld
Daemon.
In this case, you may reset your controllers by holding Legion R + RT + RB,
and then Legion L + LT + LB or booting into windows.Gyro Kernel DriversWhich kernel patch is required will depend on your device's bosch module.
For the Bosch 260 IMU, you will need thebmi260-dkmsdriver.
For the Bosch 160 IMU and certain devices, you will need the following bmi160kernel patch.
Ayaneo Air Plus and Ally use the Bosch 323 and need the patch series from
this repository:Ally Nobara Fixes.
The Legion Go does not need kernel patches.In addition, for most devices, your kernel config should also
enable the modulesSYSFS triggerwithCONFIG_IIO_SYSFS_TRIGGERandHigh resolution timer triggerwithCONFIG_IIO_HRTIMER_TRIGGER.
Both are underLinux Kernel Configuration ─> Device Drivers ─> Industrial I/O support ─> Triggers - standalone.Broken Steam Gyro CalibrationSteam gyro calibration does not corrently work due to an issue with the accelerometer
scale (bottom bar).
Since the accelerometer is not currently used for anything this is not a high
priority fix.
The gyro will work fine in games.If you get drift, you can turn onAuto-Calibrate Gyro Drift when Stationaryand
then move the top bar (gyro) right until it covers the noise.High Touchpad Sensitivity in Steam InputBy default, the Dualsense kernel driver exposes the Dualsense trackpad as a normal
trackpad.
This means that if you go to use it as steam input, you still get the normal
trackpad input.
This leads to double input.You can either disable it with the packageds-inhibitwhich detects if steam
is running and mutes it (still works in desktop) or with the following udev rule
(does not work in desktop).
Place it under/etc/udev/rules.d/99-hhd-playstation-touchpad.rules# Disables all playstation touchpads from use as touchpads.ACTION=="add|change",KERNEL=="event[0-9]*",ATTRS{name}=="*Wireless Controller Touchpad",ENV{LIBINPUT_IGNORE_DEVICE}="1"The packageds-inhibitis available in AUR, packaged for Nobara, and enabled
by default in Bazzite.Playstation Glyphs and Controller ImageIf you do not want playstation glyphs in Steam, you can usehttps://github.com/frazse/PS5-to-Xbox-glyphsas a CSS Loader plugin to switch them to Xbox.
Then, there are CSS plugins for the Legion Go and Ally controller images inhttps://github.com/frazse/SBP-Legion-Go-Themeandhttps://github.com/semakusut/SBP-ROG-Allyrespectively.
If you are using Bazzite, you can also find aujustversion of the commands in
the Bazzite readme.Missing Python EvdevIn case you have installation issues, you might be missing the packagepython-evdev.
You can either install it as part of your distribution (included by Nobara
and ChimeraOS) or automatically throughpipwith the commands above.

The latest version of Handheld Daemon becomes available at the latest the next
day after release, and can be managed through the Bazzite updater.
In addition, Bazzite contains all the required kernel patches for the Handheld Daemon
supported devices, so it is the recommended distro to use Handheld Daemon with.After install, you can useujustto install Decky and the Handheld Daemon Decky
plugin with the commandsujust get-decky,ujust get-hhd-decky.If you need to use a different Handheld Daemon version or a custom one, the
install steps do not currently work for Bazzite, but this will be fixed in the future.
Essentially, a new service file needs to be written for Bazzite that contains the
correct home path (/var/home) and then you can disable the built-in version
service and use the new one instead.Seesupported devicesto check the status of your device andafter installfor specific device quirks.❄️ NixOSEnsure yournixpkgsis on theunstablechannel (as of Feb 2024):inputs={nixpkgs.url="github:nixos/nixpkgs/nixos-unstable";and add this line to yourconfiguration.nix:services.handheld-daemon.enable=true;Distribution Installation (not recommended)You can install Handheld Daemon fromAUR(Arch) orCOPR(Fedora).

You can also install the Electron version (hhd-ui)
to use completely offline or as an app (updating it has to be done manually for now).Using DeckyIf you have decky installed, you can use the following command to
install the Handheld Daemon decky plugin (visithhd-deckyfor details).curl -L https://github.com/hhd-dev/hhd-decky/raw/main/install.sh | shThen, just open up steam.File basedThe reason you added your username to thehhdservice was to bind thehhddaemon to your user.This allows Handheld Daemon to add configuration files with appropriate
permissions to your user, in the following directory:~/.config/hhdThe global configuration for HHD is found in:~/.config/hhd/state.ymlYou can modify it and it will hot-reload upon saving.ContributingFinding the correct axis for your deviceTo figure the correct axis from your device, go to desktop and open the steam
calibration settings.
Then, go tohttps://hhd.dev, switchMotion AxistoOverrideand tweak only
the axis (without invert) of your device until they match the glyphs in steam.[!WARNING]Do not try to interpret what each axis means. You will get a headache.
Just change them randomly until
the glyphs line up with how you move your controller.
If you set multiple axis to a single one (e.g., X to Y, and Y to Y),
the first option (e.g., X to Y) option will be ignored.Then, jump in a first person game and turn onGyro to MouseorCamera.
ForGyro to Mouse, useGyro to Mouse fixif you get issues with the camera
jumping around.
By default, rotating your device like a steering wheel should turn left to right,
and rotating it to face down or up should look up or down.
Fix the invert settings of the axis so that it is intuitive.
Finally, switch the settingGyro Turning AxisfromYaw(rotate like a steering
wheel) toRoll(turn left to right), and fix the remaining axis inversion.You can now either take a picture of your screen or translate the settings into
text (e.g., x is k, y is l inverted, z is j) and open an issue.
The override setting also displays the make and model of your device, which
are required to add the mappings to Handheld Daemon.Localizing Handheld DaemonYou can findpotandpofiles for Handheld Daemon under thei18ndirectory.
