HI Jafar,

Unfortunately, turbo-fan program didn't work on my lap PT515-52. Turbo seems to work fine, but lcd keyboard does not.

I'm sending you the dsdt.aml file, and the rest of the information you ask is next:

Hope information enough for you and thanks a lot. Regards.

Hi, Unfortunately, this project only works on 4-zone RGB keyboards. I believe your laptop have per-key RGB. I don't have a model similar to you, and it can be time consuming to reverse engineer the mechanism for controlling per-key RGB.
To implement it, I'll need separate implementations and trial and errors on your laptop (with help of you). So if you think you can help me with this, drop me a message https://t.me/deallocate

Hi, how's the per-key backlight support coming along? Have you started to do any work on it, or do you consider it too cumbersome? I don't mean to push or anything, and I completely understand if you don't want to make it, but if you do, I'd love to help you. I'm kind of a noob so I doubt I'd be able to contribute anything to the code, but I do own a PT515-52 device, so if you need any testing, I'd be glad to do it.

[JafarAkhondali]

Hi @Confuze , Can you test this script? https://github.com/JafarAkhondali/acer-predator-turbo-and-rgb-keyboard-linux-module/issues/91 I don't have access to such model, neither my previous laptop, so I'm kinda stuck in further development of this project

[Confuze]

Thanks for the quick response, @JafarAkhondali I installed the hid module via pip, made the file an executable and ran it but it doesn't work (unless I did something wrong). I have very little experience with python scripting but it seems like the provided script has some errors. The shebang is missing the exclamation mark, one '(' was never closed and a couple more. I tried debugging it a little and right now I'm dealing with the following error:

Traceback (most recent call last):
  File "/home/stefanz/Downloads/./led_color_adjust.txt", line 37, in <module>
    h = hid.device()
AttributeError: module 'hid' has no attribute 'device'. Did you mean: 'Device'?

Replacing 'device' with 'Device' worked but it requires some arguments so it looks like I'm gonna have to do some research.

I know you can't really test the script but could you please have a look at the python code and tell me if you actually see anything wrong with it or am I doing something wrong? Chances are, it's just my lack of understanding the code so it could probably help. Either way, I'll try investigating a bit more myself too once I have the time.

[JafarAkhondali]

uninstall hid: pip uninstall hid then install hidapi pip install hidapi

[Confuze]

Yup, that fixes it. Script remains broken though. Once I ran it, i returned the error

  File "/home/stefanz/Downloads/./led_color_adjust.txt", line 41, in <module>
    device = [dev for dev in hl if dev['usage_page'] == 65282][0]
IndexError: list index out of range

and then I found out the hl variable is an empty array too. I changed the vendor and product IDs to what I'm pretty sure is my internal keyboard and now hl returns this:

[
    {'path': b'1-6:1.0', 'vendor_id': 3426, 'product_id': 31921, 'serial_number': '', 'release_number': 12806, 'manufacturer_string': '', 'product_string': '', 'usage_page': 0, 'usage': 0, 'interface_number': 0},
    {'path': b'1-6:1.1', 'vendor_id': 3426, 'product_id': 31921, 'serial_number': '', 'release_number': 12806, 'manufacturer_string': '', 'product_string': '', 'usage_page': 0, 'usage': 0, 'interface_number': 1},
    {'path': b'1-6:1.2', 'vendor_id': 3426, 'product_id': 31921, 'serial_number': '', 'release_number': 12806, 'manufacturer_string': '', 'product_string': '', 'usage_page': 0, 'usage': 0, 'interface_number': 2},
    {'path': b'1-6:1.3', 'vendor_id': 3426, 'product_id': 31921, 'serial_number': '', 'release_number': 12806, 'manufacturer_string': '', 'product_string': '', 'usage_page': 0, 'usage': 0, 'interface_number': 3}
]

So I've got 4 different devices all with the same properties (with the exception of interface_number) and no usage_page and usage specified. I tried testing all of them one by one and managed to run the script without any errors but it still didn't do anything.

Here's everything I have right now along with some comments:

Any ideas on what else I could try?

[JafarAkhondali]

Hmmm we may need @nqsnqsnqs input on this. For now, try booting in Windows and set the keyboard color to dynamic per key mode, then do a full reboot using this command in cmd shutdown /r /p. Then try to run the script as root and play with other parameters like mode, brightness, speed, etc. I can't think of any other options for now.

[Confuze]

Are you sure you mean shutdown /r /p? According to the documentation, /p can only be used with /f and /d.
