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.

I was googling the same problem today (wanted to play minecraft with a gamepad ;). I found joy2key, but have the same problem with mouse/mousebutton emulation. –  sBlatt Nov 22 '10 at 22:53

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.

To map a gamepad to mouse, try js2mouse.

In Ubuntu 11.10, qjoypad doesn't seem to work properly, because a left-click on its icon in the notification area triggers a right-click menu with no way to access setup. You can, however, use Rejoystick (also available in PlayDeb). The first time you run it (running rejoystick) you assign keys to your gamepad's buttons, then save. Next you run rejoystick -d and you won't get a GUI, rejoystick is running in the background and will use your gamepad's buttons for the assigned keys.

The solution is QJoyPad. As I stated in my update on the question, it does allow the mapping of both keyboard and mouse.

Amnesia is a little bit of an oddball in the configuration because the game uses, according to their forum, relative mouse movements. The solution is launch the game via a terminal after typing in export SDL_VIDEO_X11_DGAMOUSE=0. After doing so, my test with the mouse worked fine.

By the way, the controller I am using with QJoyPad is a Logitech Dual Action.
