Years ago I bought a ps4 controller to play in my Linux pc, but the games didn't recognize the controller input, I had to use some program to map the keyboard to the controllers but it didn't work well, so I installed steam and with it ir worked perfectly. Because work and college I had to stop gaming for a couple of years, and I tried again some weeks ago with Lutris, to my surprise that the controller got recognized and worked perfectly without the need for steam.
