# asusctrl manual

`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.

## Programs Available

- `asusd`: The main system daemon. It is autostarted by a udev rule and systemd unit.
- `asusd-user`: The user level daemon. Currently will run an anime sequence, with RGB keyboard sequences soon.
- `asusctl`: The CLI for interacting with the system daemon
- `asus-notify`: A notification daemon with a user systemd unit that can be enabled.

## `asusd`

`asusd` is the main system-level daemon which will control/load/save various settings in a safe way for the user, along with exposing a *safe* dbus interface for these interactions. This section covers only the daemon plus the various configuration file options.

The functionality that `asusd` exposes is:

- anime control
- led keyboard control (aura)
- charge limiting
- bios/efivar control
- power profile switching
- fan curves (if supported, this is auto-detected)

each of these will be detailed in sections.

### AniMe control

Controller for the fancy AniMe matrix display on the lid of some machines. This controller is a work in progress.

#### Config options

If you have an AniMe device a few system-level config options are enabled for you in `/etc/asusd/anime.conf`;

1. `"system": [],`: currently unused, is intended to be a default continuous sequence in future versions
2. `"boot": [],`: a sequence that plays on system boot (when asusd is loaded)
3. `"wake": [],`: a sequence that plays when waking from suspend
4. `"shutdown": [],`: a sequence that plays when shutdown begins
5. `"brightness": <FLOAT>`: global brightness control, where `<FLOAT> is 0.0-1.0

Some default examples are provided but are minimal. The full range of configuration options will be covered in another section of this manual.

### Led keyboard control

The LED controller (e.g, aura) enables setting many of the factory modes available if a laptop supports them. It also enables per-key RGB settings but this is a WIP and will likely be similar to how AniMe sequences can be created.

#### Supported laptops

Models GA401, GA502, GU502 support LED brightness change only (no RGB). However the GA401Q model can actually use three modes; static, breathe, and pulse, plus also use red to control the LED brightness intensity.

All models that have any form of LED mode control need to be enabled via the config file at `/etc/asusd/asusd-ledmodes.toml`. Unfortunately ASUS doesn't provide any easy way to find all the supported modes for all laptops (not even through Armory Crate and its various files, that progrma downloads only the required settings for the laptop it runs on) so each model must be added as needed.

#### Config options

The defaults are located at `/etc/asusd/asusd-ledmodes.toml`, and on `asusd` start it creates `/etc/asusd/aura.conf` whcih stores the per-mode settings. If you edit the defaults file you must remove `/etc/asusd/aura.conf` and restart `asusd.service` with `systemctl restart asusd`.

##### /etc/asusd/asusd-ledmodes.toml

Example:
```toml
[[led_data]]
prod_family = "Strix"
board_names = ["GL504G"]
standard = ["Static", "Breathe", "Strobe", "Rainbow", "Pulse"]
multizone = ["Key1", "Key2", "Key3", "Key4", "Logo", "BarLeft", "BarRight"]
per_key = false
```

1. `prod_family`: you can find this in `journalctl -b -u asusd`, or `cat /sys/class/dmi/id/product_name`. It should be copied as written. There can be multiple `led-data` groups of the same `prod_family` with differing `board_names`.
2. `board_names`: is an array of board names in this product family. Find this in the journal as above or by `cat /sys/class/dmi/id/board_name`.
3. `standard` are the factory preset modes, the names should corrospond to Armory Crate names
4. `multizone`: some models have 4 to 7 zones of LED control as shown in the example. If the laptop has no zones then an empty array will suffice.
5. `per_key`: enable per-key RGB effects. The keyboard must support this or it has no effect.

##### /etc/asusd/aura.conf

This file can be manually edited if desired, but the `asusctl` CLI tool, or dbus methods are the preferred method. Any manual changes to this file mean that the `asusd.service` will need to be restarted, or you need to cycle between modes to force a reload.

### Charge control

Almost all modern ASUS laptops have charging limit control now. This can be controlled in `/etc/asusd/asusd.conf`.

```json
"bat_charge_limit": 80,
```
where the number is a percentage.

### Bios control

Some options that you find in Armory Crate are available under this controller, so far there is:

- POST sound: this is the sound you hear on bios boot post
- GPU MUX: this controls if the dGPU is the *only* GPU, making it the main GPU and disabling the iGPU

These options are not written to the config file as they are stored in efivars. The only way to change these is to use the exposed safe dbus methods, or use the `asusctl` CLI tool.

### Profiles

asusctl can support setting a power profile via platform_profile drivers. This requires [power-profiles-daemon](https://gitlab.freedesktop.org/hadess/power-profiles-daemon) v0.10.0 minimum. It also requires the kernel patch for platform_profile support to be applied form [here](https://lkml.org/lkml/2021/8/18/1022) - this patch is merged to 5.15 kernel upstream.

A common use of asusctl is to bind the `fn+f5` (fan) key to `asusctl profile -n` to cycle through the 3 profiles:
1. Balanced
2. Performance
3. Quiet

#### Fan curves

Fan curve support requires a laptop that supports it (this is detected automatically) and the kernel patch from [here](https://lkml.org/lkml/2021/10/23/250) which is accepted for the 5.17 kernel release .

The fan curve format can be of varying formats:

- `30c:0%,40c:5%,50c:10%,60c:20%,70c:35%,80c:55%,90c:65%,100c:65%"`
- `30:0,40:5,50:10,60:20,70:35,80:55,90:65,100:65"`
- `30 0,40 5,50 10,60 20,70 35,80 55,90 65,100 65"`
- `30 0 40 5 50 10 60 20 70 35 80 55 90 65 100 65"`

the order must always be the same "temperature:percentage", lowest from left to rigth being highest.

The config file is located at `/etc/asusd/profile.conf` and is self-descriptive. On first run it is populated with the system EC defaults.

### Support controller

There is one more controller; the support controller. The sole pupose of this controller is to querie all the other controllers for information about their support level for the host laptop. Returns a json string.

## asusd-user

`asusd-user` is a usermode daemon. The intended purpose is to provide a method for users to run there own custom per-key keyboard effects and modes, AniMe sequences, and possibly their own profiles - all without overwriting the *base* system config. As such some parts of the system daemon will migrate to the user daemon over time with the expectation that the Linux system runs both.

As of now only AniMe is active in this with configuration in `~/.config/rog/`. On first run defaults are created that are intended to work as examples.

The main config is `~/.config/rog/rog-user.cfg`

#### Config options: Aura (per-key support only)

`~/.config/rog/rog-user.cfg` contains a setting `"active_aura": "<FILENAME>"` where `<FILENAME>` is the name of the Aura config to use, located in the same directory and without the file postfix, e.g, `"active_anime": "aura-default"`

An Aura config itself is a file with contents:

```json
{
  "name": "aura-default",
  "aura": [
    {
      "Breathe": {
        "led_type": {
          "Key": "W"
        },
        "start_colour1": [
          255,
          0,
          20
        ],
        "start_colour2": [
          20,
          255,
          0
        ],
        "speed": "Low"
      }
    },
    {
      "Static": {
        "led_type": {
          "Key": "Esc"
        },
        "colour": [
          0,
          0,
          255
        ]
      }
    },
    {
      "Flicker": {
        "led_type": {
          "Key": "N9"
        },
        "colour": [
          0,
          0,
          255
        ],
        "max_percentage": 80,
        "min_percentage": 40
      }
    }
  ]
}
```

If your laptop supports multizone, `"led_type"` can also be `"PerZone": <one of the following>`
- `"None"`
- `"KeyboardLeft"`
- `"KeyboardCenterLeft"`
- `"KeyboardCenterRight"`
- `"KeyboardRight"`
- `"LightbarRight"`
- `"LightbarRightCorner"`
- `"LightbarRightBottom"`
- `"LightbarLeftBottom"`
- `"LightbarLeftCorner"`
- `"LightbarLeft"`

At the moment there are only three effects available as shown in the example. More will come in the future
but this may take me some time.

**Aura layouts**: `asusd-user` does its best to find a suitable layout to use based on `/sys/class/dmi/id/board_name`.
It looks at each of the files in `/usr/share/rog-gui/layouts/` and matches against the toml block looking like:
```toml
matches = [
    'GX502',
    'GU502',
]
```

My laptop is a `GX502GW`, so `GX502` is a match. Note that these layouts are the physical representation of
the keyboard and are used in the GUI also. The config that tells if per-key is supported is located in
`/etc/asusd/asusd-ledmodes.toml`

#### Config options: AniMe

`~/.config/rog/rog-user.cfg` contains a setting `"active_anime": "<FILENAME>"` where `<FILENAME>` is the name of the AniMe config to use, located in the same directory and without the file postfix, e.g, `"active_anime": "anime-doom"`

An AniMe config itself is a file with contents:

```json
{
  "name": "<FILENAME>",
  "anime": []
}
```

`<FILENAME>` is used as a reference internally. `"anime": []` is an array of sequences (WIP).

##### "anime" array options

Each object in the array can be one of:

1. AsusAnimation
2. ImageAnimation
3. Image
4. Pause

##### AsusAnimation

`AsusAnimation` is specifically for running the gif files that Armory Crate comes with. `asusctl` includes all of these in `/usr/share/asusd/anime/asus/`
```json
      "AsusAnimation": {
        "file": "<FILE_PATH>",
        "time": <TIME>,
        "brightness": <FLOAT>
      }
```

##### AsusImage

Virtually the same as `AsusAnimation` but for png files, typically created in the same "slanted" style using a template (`diagonal-template.png`) as the ASUS gifs for pixel perfection.

```json
      "AsusImage": {
        "file": "<FILE_PATH>",
        "time": <TIME>,
        "brightness": <FLOAT>
      }
```

##### ImageAnimation

`ImageAnimation` can play *any* gif of any size.

```json
      "ImageAnimation": {
        "file": "<FILE_PATH>",
        "scale": <FLOAT>,
        "angle": <FLOAT>,
        "translation": [
          <FLOAT>,
          <FLOAT>
        ],
        "time": <TIME>,
        "brightness": <FLOAT>
      }
    },
```

##### Image

`Image` currently requires 8bit greyscale png. It will be able to use most in future.

```json
    {
      "Image": {
        "file": "<FILE_PATH>",
        "scale": <FLOAT>,
        "angle": <FLOAT>,
        "translation": [
          <FLOAT>,
          <FLOAT>
        ],
        "time": <TIME>,
        "brightness": <FLOAT>
      }
    },
```

##### Pause

A `Pause` is handy for after an `Image` to hold the `Image` on the AniMe for a period.

```json
    {
      "Pause": {
        "secs": <INT>,
        "nanos": <INT>
      }
    },
```

##### Options for objects

**<FILE_PATH>**

Must be full path: `"/usr/share/asusd/anime/asus/gaming/Controller.gif"` or `/home/luke/Downloads/random.gif`.

**<FLOAT>**

A number from 0.0-1.0.
- `brightness`: If it is brightness it is combined with the system daemon global brightness
- `scale`: 1.0 is the original size with lower number shrinking, larger growing
- `angle`: Rotation angle in radians
- `translation`: Shift the image X -/+, and y -/+

**<TIME>**

Time is the length of time to run the gif for:
```json
        "time": {
          "Time": {
            "secs": 5,
            "nanos": 0
          }
        },
```
A cycle is how many gif loops to run:
```json
        "time": {
          "Cycles": 2
        },
```
`Infinite` means that this gif will never end:
```json
        "time": "Infinite",
```
`Fade` allows an image or gif to fade in and out, and remain at max brightness to n time:
```json
        "time": {
          "Fade": {
            "fade_in": {
              "secs": 2,
              "nanos": 0
            },
            "show_for": {
              "secs": 1,
              "nanos": 0
            },
            "fade_out": {
              "secs": 2,
              "nanos": 0
            }
          }
        },
```
`show_for` can be `null`, if it is `null` then the `show_for` becomes `gif_time_length - fade_in - fade_out`.
This is period for which the gif or image will be max brightness (as set).

**<INT>**

A plain non-float integer.

## asusctl

`asusctl` is a commandline interface which intends to be the main method of interacting with `asusd`. It can be used in any place a terminal app can be used.

This program will query `asusd` for the `Support` level of the laptop and show or hide options according to this support level.

Most commands are self-explanatory.

### CLI Usage and help

Commands are given by:

```
asusctl <option> <command> <command-options>
```

Help is available through:

```
asusctl --help
asusctl <command> --help
```

Some commands may have subcommands:

```
asusctl <command> <subcommand> --help
```

### Keybinds

To switch to next/previous Aura modes you will need to bind both the aura keys (if available) to one of:
**Next**
```
asusctl led-mode -n
```
**Previous**
```
asusctl led-mode -p
```

To switch Fan/Thermal profiles you need to bind the Fn+F5 key to `asusctl profile -n`.

## User NOTIFICATIONS via dbus

If you have a notifications handler set up, or are using KDE or Gnome then you
can enable the user service to get basic notifications when something changes.

```
systemctl --user enable asus-notify.service
systemctl --user start asus-notify.service
```
