Gamepad Configuration – Remapping Both Mouse and Keyboard to a Gamepad

10.10configurationgamepadgames

Since Halloween, I have been really enjoying Frictional Games' Amnesia on Ubuntu. My next goal is to get the other offerings they have.

Unfortunately, there is not a gamepad setting for this game (and many others out there). I know there is software like rejoystick that allows the mapping of keyboard keys to a gamepad. However, since this game incorporates the mouse, is there a solution to map both over?

Thanks in advance.

Update: I have found on playdeb.net QJoypad. It allows the mapping of both keyboard and mouse. Unfortunately, I still seem to have trouble with the mouse when entering Amnesia.

Following Grumbel's answer, I tried xboxdrv solution with the support of his link and specially this page:

1. Install xboxdrv 0.8.2 from Ubuntu Software Center.

Install also uinput and joydev if needed. I did it this way sudo modprobe uinput + sudo modprobe joydev

2. Need to know the event of the gamepad:

Launch udevadm monitor --udev and then plug the game pad :

$ udevadm monitor --udev
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing

UDEV  [6722.377700] add      /devices/pci0000:00/0000:00:1d.3/usb5/5-1 (usb)
UDEV  [6722.383264] add      /devices/pci0000:00/0000:00:1d.3/usb5/5-1/5-1:1.0 (usb)
UDEV  [6722.383333] add      /devices/pci0000:00/0000:00:1d.3/usb5/5-1/5-1:1.0/0003:046D:C218.0003 (hid)
UDEV  [6722.383389] add      /devices/pci0000:00/0000:00:1d.3/usb5/5-1/5-1:1.0/0003:046D:C218.0003/hidraw/hidraw1 (hidraw)
UDEV  [6722.387123] add      /devices/pci0000:00/0000:00:1d.3/usb5/5-1/5-1:1.0/input/input10 (input)
UDEV  [6722.399284] add      /devices/pci0000:00/0000:00:1d.3/usb5/5-1/5-1:1.0/input/input10/event8 (input)
UDEV  [6722.412128] add      /devices/pci0000:00/0000:00:1d.3/usb5/5-1/5-1:1.0/input/input10/js0 (input)

I conclude that my gamepad's event is /dev/input/event8

3. Display names of every keys, axis, buttons of the gamepad.

The idea is to launch xboxdrv and test every buttons and note the result on paper.

$ sudo xboxdrv --evdev /dev/input/event8 --evdev-debug
Your Xbox/Xbox360 controller should now be available as:
/dev/input/js1
/dev/input/event9
Press Ctrl-c to quit, use '--silent' to suppress the event output
EV_ABS ABS_X 128
EV_ABS ABS_Y 128
...

In my case the result is: enter image description here

4. Set the config file

Create a xboxdrv-mouse.ini file to set X Y axis and left and right mouse button.
Here I set gamepad buttons 2 for left mouse button and 3 for right mouse button:

[xboxdrv]
evdev=/dev/input/event8
silent=true

[evdev-absmap]
ABS_X=x1
ABS_Y=y1

[ui-axismap]
x1=REL_X:10
y1=REL_Y:-10

[evdev-keymap]
BTN_THUMB=a
BTN_THUMB2=b

[ui-buttonmap]
a=BTN_LEFT
b=BTN_RIGHT

# EOF #

Note that value for REl_X and REL_Y seems to define the speed of the mouse, and by defining a negative value it invert the axis (see here for REL_Y)

An other example with more button definition

[xboxdrv]
evdev=/dev/input/event8
silent=true

[evdev-absmap]
ABS_X=x1
ABS_Y=y1
ABS_HAT0X=x2
ABS_HAT0Y=y2

[ui-axismap]
x1=REL_X:10
y1=REL_Y:-10
x2=KEY_LEFT:KEY_RIGHT
y2=KEY_DOWN:KEY_UP

[evdev-keymap]
BTN_TRIGGER=x
BTN_TOP=y
BTN_THUMB=a
BTN_THUMB2=b
BTN_PINKIE=rt
BTN_BASE2=rb
BTN_TOP2=lt
BTN_BASE=lb
BTN_BASE3=back
BTN_BASE4=start

[ui-buttonmap]
x=KEY_KPENTER
y=KEY_SPACE
a=BTN_LEFT
b=BTN_RIGHT
rt=KEY_KP8
rb=KEY_KP2
lt=KEY_KP6
lb=KEY_KP4
back=KEY_LEFTSHIFT
start=KEY_RIGHTCTRL

# EOF #

5. Launch it

sudo xboxdrv --config xboxdrv-mouse.ini

To avoid launching it with sudo, create a udev rule.

CONCLUSION

It works fine, it's the best solution for me.
