Inspired by faustus(for asus), this project extends current acer-wmi linux kernel module to support Acer gaming functions.

Warning

Use at your own risk! Acer was not involved in developing this driver, and everything is developed by reverse engeineering official Predator Sense app. This driver interacts with low-level WMI methods which haven't been tested on all series.

Donations are not required, but shows your ❤️ to open source and encourages me to implement more features for this project. Paypal

Note

Note to contributors:

I started to record a mini-series to share my experience in creating this project on youtube. This will definitly help you to contribute in this project or similar projects that are using WMI for communication.

Will this work on my laptop?

Compablity table:

Obviously, I don't have access to all these models, so if it worked(or not) for you, kindly please mention your model on issues so we can ship this to Linux kernel.

You can find your model using this command: sudo dmidecode -s system-product-name

I think dynamic RGB effects should work only on 4zone RGB keyboards like 300 series but haven't tested other models.

Check the output of this command:
# file /sys/bus/wmi/devices/7A4DDFE7-5B5D-40B4-8595-4408E0CC7F56/
If the directory exists, it may work fine. Otherwise, RGB will not work at all.

If you have secure boot enabled, you are not using Ubuntu and installation failed with error Key was rejected by service, you can sign the module yourself by following the instructions here.

Install linux headers using your distro package manager: Ubuntu (or other Debian baseds distros):
sudo apt-get install linux-headers-$(uname -r) gcc make

Arch (I don't use arch anymore btw):
sudo pacman -S linux-headers

git clone https://github.com/JafarAkhondali/acer-predator-turbo-and-rgb-keyboard-linux-module
cd "acer-predator-turbo-and-rgb-keyboard-linux-module"
chmod +x ./*.sh
sudo ./install.sh

# Download the latest version of Predator-Sense-CLI available)

sudo pacman -U Predator-Sense-CLI-{version}-any.pkg.tar.zst

git clone https://github.com/JafarAkhondali/acer-predator-turbo-and-rgb-keyboard-linux-module
cd "acer-predator-turbo-and-rgb-keyboard-linux-module"
chmod +x ./*.sh
sudo ./install_service.sh

git clone https://github.com/JafarAkhondali/acer-predator-turbo-and-rgb-keyboard-linux-module
cd "acer-predator-turbo-and-rgb-keyboard-linux-module"
chmod +x ./*.sh
sudo ./install_openrc.sh

Turbo mode should work fine by using the turbo button on keyboard.

For RGB, the module will mount a new character device at /dev/acer-gkbbl-0 to communicate with kernel space.
To make it easier to interact with this device, a simple python script has been attached.
./facer_rgb.py
or check help for more advanced usage:
./facer_rgb.py --help

usage: facer_rgb.py [-h] [-m MODE] [-z ZONE] [-s SPEED] [-b BRIGHTNESS] [-d DIRECTION] [-cR RED] [-cG GREEN] [-cB BLUE]

Interacts with experimental Acer-wmi kernel module.
-m [mode index]
    Effect modes:
    0 -> Static [Accepts ZoneID[1,2,3,4] + RGB Color]
    1 -> Breath [Accepts RGB color]
    2 -> Neon
    3 -> Wave
    4 -> Shifting [Accepts RGB color]
    5 -> Zoom [Accepts RGB color]

-z [ZoneID]
    Zone ID(Only in static mode):
    Possible values: 1,2,3,4

-s [speed]
    Animation Speed:
    
    0 -> No animation speed (static)
    1 -> Slowest animation speed
    9 -> Fastest animation speed
    
    You can use values between 1-9 to adjust the speed or increase speed even more than 255, but keep in mind
    that values higher than 9 were not used in the official PredatorSense application.

-b [brightness]
    Keyboard backlight Brightness:
    
    0   -> No backlight (turned off)
    100 -> Maximum backlight brightness
    
-d [direction]
    Animation direction:
    
    1   -> Right to Left
    2   -> Left to Right

-cR [red value]
    Some modes require specific [R]GB color
    
    0   -> Minimum red range
    255 -> Maximum red range

-cG [green value]
    Some modes require specific R[G]B color
    
    0   -> Minimum green range
    255 -> Maximum green range

-cB [blue value]
    Some modes require specific RG[B] color
    
    0   -> Minimum blue range
    255 -> Maximum blue range

-save [profile name]
    Add as last argument to save to a profile

-load [profile name]
    Loads the profile if it exists

-list
    Lists all the saved profiles in config directory
    config directory is "$HOME/.config/predator/saved profiles/"

optional arguments:
  -h, --help     show this help message and exit
  -m MODE
  -z ZONE
  -s SPEED
  -b BRIGHTNESS
  -d DIRECTION
  -cR RED
  -cG GREEN
  -cB BLUE
  -save NAME
  -load NAME
  -list

Sample usages:

Breath effect with Purple color(speed=4, brightness=100):
./facer_rgb.py -m 1 -s 4 -b 100 -cR 255 -cG 0 -cB 255

Neon effect(speed=3, brightness=100):
./facer_rgb.py -m 2 -s 3 -b 100

Wave effect(speed=5, brightness=100):
./facer_rgb.py -m 3 -s 5 -b 100

Shifting effect with Blue color (speed=5, brightness=100):
./facer_rgb.py -m 4 -s 5 -b 100 -cR 0 -cB 255 -cG 0

Zoom effect with Green color (speed=7, brightness=100):
./facer_rgb.py -m 5 -s 7 -b 100 -cR 0 -cB 0 -cG 255

Static waving (speed=0): ./facer_rgb.py -m 3 -s 0 -b 100

Static mode coloring (zone=1 => most left zone, color=blue):
./facer_rgb.py -m 0 -z 1 -cR 0 -cB 255 -cG 0

Static mode coloring (zone=4 => most right zone, color=purple) and save it as example:
./facer_rgb.py -m 0 -z 4 -cR 255 -cB 255 -cG 0

Load the previously saved profile: ./facer_rgb.py -load example

If installation failed, check this issue If something didn't look right, do a reboot (or boot to windows) and play a little with some Predator Sense app to reset ACPI registers.

Simply run ./uninstall.sh and (hopefully) everything should be back to normal.
If you have installed it as a service, simply run ./uninstal_service.sh

If you install it from AUR repository RUN sudo pacman -R Predator-Sense-systemd-git

If this worked or didn't worked for you, kindly make a new issue, and attach the following if possible:
sudo dmidecode | grep "Product Name" -B 2 -A 4
sudo cat /sys/firmware/acpi/tables/DSDT > dsdt.aml
