Fix to use dualsense controller in hollow knight on linux

Map dualsense controller manually and disable Steam Input

This fixes the issue of swapped buttons and Triggers in the dualsense controller opening the pause menu The issue is caused by the SDL version used by hollow knight not recognizing the dualsense controller and mapping buttons properly. It is also not helped by steam input not disabling the native controller support when used in hollow knight. The issue cannot be fixed by simple mapping in steam input.

1. Disable Steam Input
2. Set the following as launch option

SDL_GAMECONTROLLERCONFIG="050000004c050000e60c000000810000,Sony DualSense ,a:b0,b:b1,back:b8,dpdown:h0.4,dpleft:h0.8,dpright:h0.2,dpup:h0.1,guide:b10,leftshoulder:b4,leftstick:b11,lefttrigger:a2,leftx:a0,lefty:a1,rightshoulder:b5,rightstick:b12,righttrigger:a5,rightx:a3,righty:a4,start:b9,x:b3,y:b2,platform:Linux," %command%

Use libSDL2 from Steam runtime:

If the above doesn't work. Try the following.

You can also try making the game use libSDL2 from Steam runtime

SDL_DYNAMIC_API=/home/USERNAME/.steam/root/ubuntu12_32/steam-runtime/usr/lib/x86_64-linux-gnu/libSDL2-2.0.so.0 %command%

(where USERNAME should be replaced with your OS user name)

Thank you so much, the SDL2 settings did it. This makes even the sticks work. Please do a steam guide on this for the game.

Thank you!!! Lifesaver :p

SDL_DYNAMIC_API=/home/USERNAME/.steam/root/ubuntu12_32/steam-runtime/usr/lib/x86_64-linux-gnu/libSDL2-2.0.so.0 %command%

Omg this worked for me, thank you so much! Been trying to fix this for a while now. I am on Debian, so I changed it around a bit to this: SDL_DYNAMIC_API=/home/USERNAME/.steam/root/debian-installation/ubuntu12_32/steam-runtime/usr/lib/x86_64-linux-gnu/libSDL2-2.0.so.0 %command%

For MacOS - https://gist.github.com/excellproj/5f54dc626a9406afffef6730fe7e918b

the libsdl2 startup command works, thanks!

For some unknown reason, it doesn't work at all. I tried both the first and second methods on Linux and got no results. The second command looks like this:
SDL_DYNAMIC_API=/home/niki/.steam/root/ubuntu12_32/steam-runtime/usr/lib/x86_64-linux-gnu/libSDL2-2.0.so.0 %command%
Maybe you can tell me, I think that doing something wrong.

@ExtraBurrito Have you tried to follow the path in the command? Maybe you have debian or an other distribution so you need to alter the command like @CWinarski did. The path only points to the installed driver

@mad-the-one No, i have cachyos - Arch based distro, I tried to find the file manually in this path and found it with exactly the same name
