# ASUS NB Ctrl

**NOTICE:**

This program requires the kernel patch in `./kernel-patch/` to be applied.
As of 04/08/2020 these have been submitted to lkml.

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 will not get RGB control in kernel (yet), and asusd is still required to
change modes and RGB settings. The previous version of this program is named
`rog-core` and takes full control of the interfaces required - if you can't
apply the kernel patches then `rog-core` is still highly usable.

asusd is a utility for Linux to control many aspects of various ASUS laptops.

## SUPPORTED LAPTOPS

If your laptop is not in the following lists, it may still work with fan-mode switching and charge limit control.

**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.

**NOTE:** If charge limit or fan modes are not working, then you may require a kernel newer than 5.6.10.

### KEYBOARD BACKLIGHT MODES

Models GA401, GA502, GU502 support LED brightness change only (no RGB).

## Implemented

- [X] Daemon
- [X] Setting/modifying built-in LED modes
- [X] Per-key LED setting
- [X] Fancy LED modes (See examples)
- [X] Saving settings for reload
- [X] Logging - required for journalctl
- [X] AniMatrix display on G14 models that include it
- [X] Set battery charge limit (with kernel supporting this)

## Requirements for compiling

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

## Installing

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, or at least limiting use of the power-management parts as `asusd` 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 asusd parts. It is safe to leave `system76-power.service` enabled and use for switching between graphics modes.

## Uninstalling

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

## Updating

Occasionally you need to remove `/etc/asusd.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).

# Usage

**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:

```
asusd <option> <command> <command-options>
```

Help is available through:

```
asusd --help
asusd <command> --help
```

Some commands may have subcommands:

```
asusd <command> <subcommand> --help
```

### Example

```

Available commands:
  stable        set a single static colour
  breathe       pulse between one or two colours
  strobe        strobe through all colours
  rainbow       rainbow cycling in one of four directions

$ asusd led-mode stable --help
Usage: asusd led-mode stable [OPTIONS]

Optional arguments:
  -h, --help  print help message
  -c HEX      set the RGB value e.g, ff00ff

$ asusd led-mode star --help
Usage: asusd led-mode star [OPTIONS]

Optional arguments:
  -h, --help  print help message
  -c HEX      set the first RGB value e.g, ff00ff
  -C HEX      set the second RGB value e.g, ff00ff
  -s SPEED    set the speed: low, med, high
```

## 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`.
