Hello, I've just registered, and although I'm not using LFS, this thread pops up in google search for "force feedback g27 linux".

So, I'm running Euro Truck Simulator 2 (ETS2) and the force feedback is not present, and MadCatX explained why. fftest indeed does show "constant force" working, but none others. I am running Arch Linux.

The point of my post is to basically confirm that Force Feedback is not working on Logitech G27 steering wheel controller, at least not in Euro Truck Simulator 2.

Now I'll look into patching the kernel, as per previous posts.
