asusctl for ASUS ROG

- Asus Linux Website

asusd is a utility for Linux to control many aspects of various ASUS laptops but can also be used with non-asus laptops with reduced features.

Goals

1. To provide an interface for rootless control of some system functions most users wish to control such as fan speeds, keyboard LEDs, graphics modes.
2. Enable third-party apps to use the above with dbus methods
3. To make the above as easy as possible for new users
4. Respect the users resources: be small, light, and fast

Point 3 means that the list of supported distros is very narrow - fedora is explicitly supported, while Ubuntu and openSUSE are level-2 support. All other distros are not supported (while asusd might still run fine on them). For best support use fedora 32+ Workstation.

Point 4? asusd currently uses a tiny fraction of cpu time, and less than 1Mb of ram, the way a system-level daemon should.

NOTICE:

Various patches are required for keyboard support. See this post for details on status and which kernels will have which patches.

SUPPORTED LAPTOPS

Most ASUS gaming laptops that have a USB keyboard. If lsusb shows something similar to this:

Bus 001 Device 002: ID 0b05:1866 ASUSTek Computer, Inc. N-KEY Device

then it may work without tweaks. Technically all other functions except the LED and AniMe parts should work regardless of your latop make. Eventually this project will probably suffer another rename once it becomes generic enough to do so.

Implemented

• System daemon
• User notifications daemon
• Setting/modifying built-in LED modes
• Per-key LED setting
• Fancy LED modes (See examples) (currently being reworked)
• Saving settings for reload
• Logging - required for journalctl
• AniMatrix display on G14 models that include it (currently being reworked)
• Set battery charge limit (with kernel supporting this)
• Fan curve control on G14 + G15 thanks to @Yarn1
• Graphics mode switching between iGPU, dGPU, on-demand, and vfio (for VM pass-through)
  • Requires only a logout/login
• Toggle bios setting for boot/POST sound
• Toggle bios setting for "dedicated gfx" mode on supported laptops (g-sync)

BUILDING

Requirements are rust >= 1.47 installed from rustup.io if the distro provided version is too old, and make.

Ubuntu:* apt install libclang-dev libudev-dev

fedora: dnf install clang-devel systemd-devel

Installing

Download repositories are available here for the latest versions of Fedora, Ubuntu, and openSUSE.

Run make then sudo make install then reboot.

The default init method is to use the udev rule, this ensures that the service is started when the device is initialised and ready.

If you are upgrading from a previous installed version, you will need to restart the service or reboot.

$ systemctl daemon-reload && systemctl restart asusd

You may also need to activate the service for debian install. If running Pop!_OS, I suggest disabling system76-power gnome-shell extension and systemd service.

If you would like to run this daemon on another non-ASUS laptop you can. You'll have all features available except the LED and AniMe control (further controllers can be added on request). You will need to install the alternative service from data/asusd-alt.service.

Uninstalling

Run sudo make uninstall in the source repo, and remove /etc/asusd/.
