Edit: found the solution. It wasn’t haptics settings for the trackpad, but haptics settings for the left stick that needed to be switched off.

I got an issue I just cannot wrap my head around. I got Dark Forces via Steam, the original version. I downloaded the most popular controller layout for Steamdeck, however it is really annoying to use since for some reasons when I move around using the left stick, the left trackpad starts vibrating as if I move via that.

This is not a hardware issue, I play plenty of games that use the left stick, which other than Dark Forces never leads to the left trackpad vibrating. Also I found a different controller layout that I liked for Dark Forces, where this issue isn’t happening.

Now why do I still bring it up. I hear of the Force Engine project that modernised Dark Forces quite a bit. Required some tinkering, but got it working on the Steamdeck. Managed to copy over my layout from original Dark Forces. Again, left trackpad vibrating when left stick is moved.

What setting do I need to try to get rid of this? I tried removing any mapping from the trackpad, this didn’t help. I found buried in some submenus a setting that was called haptics, I also switched that off. No change. It is really annoying and I just want to know which setting is causing this.

I tried searching online, but all I am getting is people saying it’s a hardware issue. Hope you agree, in my case it is not.
