g910-gkey-uinput's Issues

sorta fixed the g-keys

So, once you deactivate the default mapping to f1-f9 with g910-led -gkm 1, you can capture / map / do whatever you want:

here's the dirty version that maps g1/g2 to copy/paste

How does it work and how can we install it?

Hi, I would have liked to know how this script works which (if I understood correctly) should allow to use the G keys of the G910 keyboards, and how to install it.

Indeed, I installed, with pip, python-uinput, pyudev, glob3 and hidraw.

┌─(~/g910-gkey-uinput)──────────────────────────────────────────(troupal@name-of-net:pts/0)─┐
└─(18:50:16 on master)──> sudo pip install python-uinput hidraw pyudev glob3

When I run the script with python, I don't get any answers to indicate that it works, and the G keys are always the same as the Fx keys. And when I stop the script with Ctrl-C, I get an error that says:

┌─(~/g910-gkey-uinput)──────────────────────────────────────────(troupal@name-of-net:pts/0)─┐
└─(18:50:16 on master)──> python g910-gkey-uinput.py  
Traceback (most recent call last):
  File "g910-gkey-uinput. py", line 33, in <module>
    binary = f. read (20)
KeyboardInterrupt

Getting this to work on my setup

I've been trying for ages to get my g910 g/m keys to work. This repo seems to handle this issue

Current setup:
Tested with xev/showkey:

My g keys are recognized as F keys.
My m keys are unresponsive

Edited the file to get this usbcode(or whatever it is ^^):
Device('/sys/devices/pci0000:00/0000:00:14.0/usb3/3-9/3-9:1.1/0003:046D:C32B.000B/hidraw/hidraw1')
Device('/sys/devices/pci0000:00/0000:00:14.0/usb3/3-9/3-9:1.0/0003:046D:C32B.000A/hidraw/hidraw0')

It runs, but neither work. I've unplugged every usb and this is what remains, so I'm 99.99% sure that that is my g910.

I've read here: MatMoul/g810-led#39 that you also use that repo.
Is it neccecary?

If you have time, could you give me a push in the right direction?
