Not detecting PushToListen keys not coming from physical keyboard

[Cat-Lady]

I am using qjoypad, a program which can map physical controller (joystick) buttons to sending fake keyboard/mouse events, via xtest fake key events. Virtually any program - from games, through electron application (discord) to terminal or text editors can detect keys pressed via this method. After all, it is pretty low level (xserver level)

Sadly, LinVAM doesn't react at all to PushToListen key mapped this way. In fact, it seems to ignore any way of faking key events - xdotool or ydotool ones included. It reacts only to physical keyboard press. Seems that it bypasses X in this regard?

It would be great of it would listen to PushToListen bind a little bit less... Low level, to allow any sensible way of mapping the key we want it to listen too, executed via device of preference.

LinVAM uses /dev/uinput for sending events and /dev/input/ devices for listening to events, which is in my knowledge the lowest level a program can go and is not dependent on any DE or windowing system. Basically it's listening for events on kernel level, I think. I haven't encountered that program before, so I'll try it and see what's going on in the background.
To confirm, this is the program you are using https://github.com/panzi/qjoypad?

Yes, albeit the main repo seems abandoned (no response to pull requests for ages), so I am using this (mine) fork with adds some additional functionality:

I get that LinVAM listening on such low level have huge benefits, but at least for own pushtotalk, having an option (maybe as an alternative, like --use-ydotool is) to listen for wider range of ways sending the event would be very beneficial. As it stands now, there is no way to send pushtotalk from joystick axis or button, for example (while it is trivial to assign axis range or button to keyboard event, LinVAM can't listen to the result).

I'll take a look and see what I can do. I'll leave a message here once I have enough info to make a decision.
I do have a plan to add joystick and gamepad support sometimes in the future tho, but not sure when that's going to happen.
