[New Model Support] Acer ALG AL15-G53 ACPI Dump & Fn Hotkeys #266
Description
- Problem Description
The keyboard backlight on your Acer ALG AL15-G53 cannot be operated in Pop!_OS for the following reasons:
Hardware Lock (EC Protocol)
Your laptop's backlight is controlled by its Embedded Controller (EC) chip, which manages low-level hardware functions. The specific EC in the AL15-G53 uses a proprietary communication protocol designed exclusively to respond to the Windows application, NitroSense.
Software Failure Points
Fn Keys Failed: Your dedicated hotkeys (Fn++,-,/,*) do not work because the Linux kernel does not recognize or process the signal sent by the EC for those specific key combinations.
Linux Interface Failure: The kernel does not expose a standard control file for the keyboard backlight in /sys/class/leds/ or through brightnessctl.
Community Driver Failure: The existing third-party Linux module for Acer gaming laptops (acer-predator-turbo-and-rgb-keyboard-linux-module) does not yet include the reverse-engineered codes for your ALG model.
- Solution Status: Data Collection Complete ✅
You have successfully completed the most crucial step required by the developer community: extracting the ACPI Tables.
The files you generated (dsdt.dat and ssdt1.dat through ssdt24.dat) contain the entire firmware map of your laptop, including the hidden ACPI methods and WMI calls used to communicate with the EC.
- Final Action (The Contribution)
The job is now transitioned from diagnostic testing to contributing your data to the developers who will write the fix.
Locate and Compress the Files: Gather all the .dat files created by acpixtract in your home directory.
Upload the Zip File: Upload the compressed file (e.g., Acer_ALG_AL15G53_ACPI_Dump.zip) to a file sharing service and make the link public.
Submit the Issue: Go to the GitHub repository for the Acer gaming module and create a new issue with the following details:
Title: [New Model Support] Acer ALG AL15-G53 ACPI Dump & Fn Hotkeys
Model: Acer ALG AL15-G53
ACPI Dump Link: [Insert your public sharing link here
Acer_ALG_AL15G53_ACPI_Dump.zip
Hotkeys: Fn++ (Increase), Fn+- (Decrease), Fn+/ (Launch App), Fn+* (Toggle/Mode).
Result: Explain that the existing module failed, and you hope this data allows for the new EC protocol to be implemented.
This contribution is the necessary step to create the module that will eventually bring your keyboard backlight control to Pop!_OS.
