Add support to M15R3 per key rgb lights keyboard #102

Open samuaz opened 2 years ago

samuaz commented 2 years ago

Hello, thanks for the hard work.

I have an Alienware M15R3, I see there is a configuration profile for this model, but my model has a per key light keyboard, I change the colors but nothing happen.

It must be difficult to map each of the keys, but would it be possible to apply at least by zone or to the entire keyboard?

if i use the block-testing i see this Resource busy error:

Traceback (most recent call last):

Thanks.

Hello @samuaz ,

Mapping a light to each key is possible because AKBL has a dynamic configuration file. Then for doing that the block testing window must work. I don't know how to fix the usb.core.USBError: [Errno 16] Resource busy problem because I cant reproduce it on my computer, but that may be caused by the LD_PRELOAD patch. Here you have some info:

Maybe removing the LD_PRELOAD for using the native libusb-1.0.so.0 will make it work. and in other cases, maybe updating the library to the last Ubuntu release will also make it work.

if you have more info please keep me updated, Best Regards, rsm

@rsm-gh thanks for the reply, i will try to fix the sb.core.USBError: [Errno 16] Resource busy and try to do the block testing.

Right now, I'm running Arch Linux.

Removing the LD_PRELOAD or replace the lib with the latest from ubuntu i get:

    raise USBError(_strerror(ret), ret, _libusb_errno[ret])
usb.core.USBError: [Errno 2] Entity not found

another information is that when block testing starts detect my external alienware 510k keyboard by default instead of my laptop keyboard

i continue investigating.
