I don't know that ultimate i-PAC controller nor MoltenGamepad.
What do you actually want to do? It's not recognized properly in games?
I was thinking about AntiMicroX but I'm not sure if it fits for your issue.

For MoltenGamepad it's available in the AUR (so available on Manjaro), did you tried to install it that way?

i have already installed AntiMicroX but i think it works the other way around, typing keys with a controller.

Thanks for the AUR info is it possible to only install selected things from AUR, i have some mixed experince with ubuntu and bleeding edge ppa's

I'm not sure if you're into programming, but the UInput system and evdev bindings for Oython makes it very easy to create your own keyboard to gamepad wrapper.

Very (very!) basic example below:

 
#!/usr/bin/python3

# Very simple keyboard (WASD) to 4-button gamepad example,
# Requires the python-evdev package.
# Run as root!
#
# Use evtest as root to find keyboard path

from evdev import InputDevice, UInput, ecodes as e

dev = InputDevice('/dev/input/event3') # <- Needs to be changed to your keyboard!

wasd_keys = [e.KEY_W, e.KEY_A, e.KEY_S, e.KEY_D]
controller_keys = [e.BTN_X, e.BTN_Y, e.BTN_B, e.BTN_A]
cap = {
    e.EV_KEY : controller_keys,
}

ui = UInput(cap, name='Totally an Xbox controller', version=0x3)

for event in dev.read_loop():
    if event.type == e.EV_KEY:
        if event.code in wasd_keys:
            index = wasd_keys.index(event.code)
            ui.write(e.EV_KEY, controller_keys[index], event.value)
            ui.syn()

i do some basic programing / scripting and i think that one looks like something i can figure out
is it possible to start this when i launch a steam game and kill it when the game quits.

i could be cool if i could control gnome dash 2 dock whit controller stick and a emulated mouse left click button and when i launch a steam game the script takes over the controller and when i launch the qmc2 frontend (M.A.M.E) it uses default keyboard settings, if steam windows is in focus (xdotool) use xbox script

As long as the package you are building from AUR compiles, links and works with existing dependencies on your system, yes.

For this one here:
https://aur.archlinux.org/packages/moltengamepad

You're going to need some additional dependencies not provided by the distro, but installing these will not affect anything else if you don't have them. (They are libraries for interfacing with the Steam Controller)


scraw (scraw-git)
scrawpp (scrawpp-git)

When you see it given like that, it means you can use either scraw or scraw-git (from AUR in this case)

This doc building tool is available in the distro, but it's also a dependency for the build (only)

go-md2man (make)

both MoltenGamepad and MoltenGamepad-git fails to build tried yay and the packetmanager.
i also tried a git clone and adding the memory fix but this also fails

this is a little over my compile skills

not shure i understand, i replaced keys from evtest

it does nothing and when i Ctrl+c it print this

can you point me to some documentation :)

Yeah, I'm not familiar with the project and its code base but it figures:

Last Updated: 2022-02-18 17:57 (UTC)

It's likely that the last time the PKGBUILD maintainer built this was with gcc 11.2 and its libstdc++

Even the moltengamepad-git build is using code that is 3 to 7 years old. (last commit on Oct 22, 2020)

It looks like a dead project. I don't know if coding around this one error would be the only land mine in the build, stuff like this can really get me chasing my tail (especially since my programming knowledge consists of needing examples to fix things if it's not obvious)

Quoting: c00kie55wasd_keys = [e.KEY_UP, e.KEY_LEFT, e.KEY_DOWN, e.KEY_RIGHT]
controller_keys = [e.KEY_LEFTALT, e.KEY_1, e.KEY_SPACE, e.KEY_LEFTCTRL]

So, the wasd_keys variable are the keyboard keys on your physical controller. The controller_keys variable are the button presses to be emitted on the virtual controller.

Apologies for the confusion!

You need to switch them around and find suitable gamepad events to emit. I used the XYAB button events in my example, but there's a long list of event codes here:
https://github.com/torvalds/linux/blob/master/include/uapi/linux/input-event-codes.h

There's good documentation and a quite thorough tutorial for python-evdev here:
https://python-evdev.readthedocs.io/en/latest/tutorial.html

Quoting: GroganIt looks like a dead project.

anyway i learned how to enable AUR

Quoting: whizseApologies for the confusion!

this looks good i will just have to dig into the documentation.
