Acer Nitro 5 (AN515-57) wmi/devices directory exists but with a prefix

[rithvikvibhu]

The README says that if this directory exists, it may work. But I seem to have a directory with a prefix PNP0C14:00-.

Will this work (with or without changes to the code)? Thanks!

Hi, regardless of the existence of file, I don't think module would work for you. Current implementations for Nitro series didn't work with turbo mode, and your keyboard is not a 4-zone RGB. If your keyboard supports dynamic effect, it may work but again I'm not sure. I think it should be safe to test.

The keyboard has 4 zones, I'll change the directory string and try it out and keep this issue updated.

[*] Done

Right after the install and every time the python script is run, the keyboard blinks off for a short while (~0.2 secs). But the colors don't change.

So guess it's not possible even if the keyboard has 4 zones? or is there any hope :p

Randomly decided to check back and came across https://github.com/JafarAkhondali/acer-predator-turbo-and-rgb-keyboard-linux-module/issues/21. Tried out the latest code and it works! Thanks @hornc
