This driver provides a sysfs interface for RGB control.
Supported devices include:
- AIR
- AIR Pro
- AIR Plus
- AIR 1s
- 2
- 2S
- GEEK
- GEEK 1S
- KUN
- Slide
If you only want to build and test the module (you need headers for your kernel):
$ git clone https://github.com/ShadowBlip/ayaneo-platform.git
$ cd ayaneo-platform
$ makeThen insert the module and check dmesg:
# insmod ayaneo-platform.koYou'll need appropriate headers for your kernel and dkms package from your
distribution.
$ git clone https://github.com/ShadowBlip/ayaneo-platform.git
$ cd ayaneo-platform
$ make
# make dkmsLED color and brightness can be controlled via sysfs.
On most systems this will be mounted at /sys/class/leds/multicolor:chassis/ and provides the following files:
Read/write.
Gets or sets the overall brightness of the LEDs. Accepts a value between 0 and max_brightness.
Defaults to 0.
Read only.
Gets the maximum brightness supported by the LEDs. On most systems this value is 255.
Read only.
Gets the names of each of the channels supported by multi_intensity. On most systems this value will be "red green blue".
Read/write.
Gets or sets the intensity of each of the channels. The expected value is list of numbers between 0 and 255 for each of the channels listed in multi_index.
Default is "0 0 0".
Read/write.
Controls how the LEDs should behave during suspend. When reading, the currently selected option will be wrapped in square brackets [ ].
| Value | Description |
|---|---|
| oem | The LEDs retain OEM behavior.On most devices, they will breathe white during suspend and breathe red when charging. |
| off | The LEDs are turned off during suspend. They do not respond to charging. |
| keep | The LEDs retain their current color during suspend. They do not respond to charging. |
Default is "oem".
The current brightness and color can be retrieved as follows:
$ cat /sys/class/leds/multicolor:chassis/brightness
0
$ cat /sys/class/leds/multicolor:chassis/multi_intensity
0 0 0New values can be set as follows:
$ echo "255" | sudo tee /sys/class/leds/multicolor:chassis/brightness
255
$ echo "255 0 128" | sudo tee /sys/class/leds/multicolor:chassis/multi_intensity
255 0 128The platform driver is fully exposed over systemd udev. This can be used to write udev rules that set attributes at startup.
$ udevadm info --attribute-walk /sys/class/leds/multicolor:chassis

All rules will start like this:
ACTION=="add|change", KERNEL=="multicolor:chassis", SUBSYSTEM=="leds"
To define a default, add the attribute in the format ATTR{name}=value
Valid attributes are:
ATTR{brightness}=="[0-255]"
ATTR{multi_intensity}=="[0-255] [0-255] [0-255]"
ATTR{suspend_mode}=="[oem|keep|off]"
As en example, to set suspend_modeto off:
ACTION=="add|change", KERNEL=="multicolor:chassis", SUBSYSTEM=="leds", ATTR{suspend_mode}="off"
to create the rule in one line:
$ echo 'ACTION=="add|change", KERNEL=="multicolor:chassis", SUBSYSTEM=="leds", ATTR{suspend_mode}="off"' | sudo tee /etc/udev/rules.d/99-led_suspend_mode.rules
