[Linux] Can't set up Logitech Wingman Formula Force GP

[jojojo8359]

Hi all,

I am currently trying to set up a Logitech Wingman Formula Force GP steering wheel with DiRT Rally on Linux.

Here's what I've done so far:

1. Used jstest-gtk to calibrate the steering wheel. The wheel has 3 axis: X = steering, Y = acceleration, and Z = brake. It also has 6 different buttons: 2 for gear shifting, and four on the center of the wheel for looking + handbrake. I can get the wheel fully calibrated in Linux using jstest-gtk perfectly fine (as seen in image 1[imgur.com]).

2. In addition to using jstest-gtk, I followed the steps listed here[wiki.archlinux.org] to verify that the wheel was properly connected, and, most importantly, tested ForceFeedback with ffcfstress. Everything mentioned in this article works with the wheel on the OS layer.

3. After setting up the wheel on the OS layer came setting the control scheme in-game. When selecting a new preset (for a steering wheel), every action in the list can be bound, except for the Brake/Reverse option (as seen in image 2[imgur.com]). The Acceleration option is bound to "Down Y-Axis", which is correct with my setup, but pressing the brake pedal when prompted yields no results. (Keep in mind that the brake pedal is bound to the Z-Axis, which is normally recognized with other steering wheel controllers.)

After discovering the game wouldn't accept the brake pedal input, I...

4. Edited the inputdevices.json file (as mentioned in this post), using the correct information for the Wingman:

{
    	"Name": "Logitech WingMan Formula Force GP",
    	"VendorID": "0x46d",
    	"ProductIDs": [
    		"0xc293"
    	],
    	"Category": "Wheel",
    	"Type": "UnknownWheel"
    }

This did not help the brake pedal situation, or anything else of note.

5. Deleted the forcefeedback/ and input/ folders from the game data, then revalidated the game's files. Did not help anything.

6. Tried making my own makeshift input control scheme file (similar to the ones in the input/ folder). Not only do I think I formatted this file wrong, I did not know how to make the game recognize it, and if it did recognize the file, nothing changed in-game- I was still not able to map the brake pedal.

After spending countless hours combing through dozens of discussion posts, watching somewhat relevant (but not too helpful) YouTube videos, and researching everything related to this issue, I have come up with nothing.

If you would like more information about the steering wheel, system information, game settings, etc., I would be happy to provide.

Thank you in advance for any light you can shed on this situation!
