NOTICE: I have completed kernel patches to move a large chunk of rog-core functionality in to the Linux kernel. The patch is not in mainline yet, but can be found in the ./kernel-patch/ directory. The patch enables the following in kernel:

  • All hotkeys (FN+Key combos)
  • Control of keyboard brightness using FN+Key combos (not RGB)
  • FN+F5 (fan) to toggle fan modes. You can watch the path /sys/devices/platform/asus-nb-wmi/throttle_thermal_policy to see which mode you are in

You will not get RGB control in kernel (yet), and rog-core is still required to change modes and RGB settings. The current version in master and last release still take full control of the interfaces

work on a version of rog-core for use with the kernel patch is in another branch

The last version of rog-core will work with any kernel with or without this patch and provide full functions.

rog-core is a utility for Linux to control many aspects (eventually) of the ASUS ROG laptops like the Zephyrus GX502GW.

One of the benefits of this app (for me at least) is that you don't require a kernel with correct support for the laptop keyboard EC. The app reads and writes direct to the device interrupts, and can be customised (in source) quite extensively to do what you want such as directly controlling your laptop backlight rather than emitting a key-press for the DE to handle.

Other laptop functions such as fan modes or battery charge limiting will need kernel level support which exists in most newer kernels (higher than 5.6.10).

Please help test or provide info for:

  • GL703(0x1869)
  • GL553/GL753 (device = 0x1854) (attempted support from researching 2nd-hand info, multizone may work)

Laptop support is modified on a per-case basis as the EC for the keyboard varies a little between models, e.g, some RGB modes are missing, or it's a single colour. As far as I can see, the EC does not give us a way to find what modes are supported.


Media keys are Volume -/+, Mute output, previous, next, play/pause. These keys are grouped together on one interface block on the keyboard EC as a "Consumer Device" HID, all other fn+ combo are on another interface which is "Vendor Custom", this includes things like keyboard LED brightness and mode change keys, Calc, fan-mode toggles etc.

Requirements for compiling

  • rustc + cargo + make
  • libusb-1.0-0-dev
  • libdbus-1-dev
  • llvm
  • libclang-dev


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 rog-core

You may also need to activate the service for debian install. If running Pop!_OS, I suggest disabling system76-power gnome-shell extension, or at least limiting use of the power-management parts as rog-core lets you set the same things (one or the other will overwrite pstates). I will create a shell extension at some point similar to system76, but using the rog-core parts. It is safe to leave system76-power.service enabled and use for switching between graphics modes.

Ubuntu PPA

Alternatively, instead of building manually you can use the PPA.

sudo add-apt-repository ppa:lukedjones/rog-core
sudo apt-get update
sudo apt-get install rog-core

the rog-core service will run when the device is initialised.

Gentoo ebuild

Thanks to @aspann you can grab it here sys-power/rog-core

Arch AUR

You can find the thingimajig here. If you are using a GA14 or GA15 series, you may need kernel patches.


Occasionally I might break things for you by tweaking or changing the config file layout. Usually this will mean you need to remove /etc/rog-core.conf and restart the daemon to create a new one. You can back up the old one and copy settings back over (then restart daemon again).


NOTE! Fan mode toggling requires a newer kernel. I'm unsure when the patches required for it got merged - I've tested with the 5.6.6 kernel and above only. To see if the fan-mode changed cat either:

  • cat /sys/devices/platform/asus-nb-wmi/throttle_thermal_policy or
  • cat /sys/devices/platform/asus-nb-wmi/fan_boost_mode

The numbers are 0 = Normal/Balanced, 1 = Boost, 2 = Silent.

Running the program as a daemon manually will require root. Standard (non-daemon) mode expects to be communicating with the daemon mode over dbus.

Commands are given by:

rog-core <option> <command> <command-options>

Help is available through:

rog-core --help

The ROG key can be customized in a limited way by use of presets:

  • Power
  • Sleep
  • MediaRecord
  • MediaFastFwd
  • MediaRewind
  • MediaNext
  • MediaPrev
  • MediaStop
  • MediaPlayPause
  • MediaVolMute
  • MediaVolUp
  • MediaVolDown
  • BacklightInc
  • BacklightDec
  • ControlConfig
  • LaunchTextEditor
  • LaunchEmailApp
  • LaunchNewsReader
  • LaunchCalendar
  • LaunchCalculator
  • LaunchWebBrowser
  • FileBrowser

This key can be changed in /etc/rogcore.conf, for example:

  "rog_key": "FileBrowser",

Daemon mode

If the daemon service is enabled then on boot the following will be reloaded from save:

  • LED brightness
  • Last used built-in mode
  • fan-boost/thermal mode
  • battery charging limit

The daemon also saves the settings per mode as the keyboard does not do this itself - this means cycling through modes with the Aura keys will use the settings that were used via CLI.

Daemon mode creates a config file at /etc/rogcore.conf which you can edit a little of. Most parts will be byte arrays, but you can adjust things like mode_performance.

You will want to look at what MeuMeu has done with

Wireshark captures

TODO: see ./wireshark_data/ for some captures.

Supporting more laptops

At a minimum it probably needs to be a Zephyrus laptop. If there is enough interest I will remove the restriction on board names so that anyone can try the app.

From there I'll need wireshark captures from Windows using Armoury Crate if possible:

  • No USB devices plugged in
  • One action per capture, 2 or 3 times
  • An action may be switching a mode or pressing a button

The real ticket items are:

  • Captures from installing Armoury Crate. To do this you need to uninstall almost all ASUS junkware and such
  • Byte sequence captures from hotkeys pressed in linux (which I need to make a tool for)
  • lsusb output


First do lsusb |grep 0b05 and check the part after 0b05:, output looks like:

Bus 001 Device 005: ID 0b05:1866 ASUSTek Computer, Inc. N-KEY Device

Then do sudo lsusb -vd 0b05:1866 > ~/laptop_info and give that to me.

Other helpful info can be gained from sudo usbhid-dump, for which you may need to unload kernel drivers. Please google this.

Also required (for my book-keeping of data):

  • cat /sys/class/dmi/id/product_name
  • cat /sys/class/dmi/id/product_family
  • cat /sys/class/dmi/id/board_name
