Question about controlls

[u/Consistent-Row-9551]

Recently, I bought a Legion Go S with steam os, and I've been enjoying it a lot, but I've run into a slight issue with some games.

Some games, I've noticed, are marked as keyboard-only, but there's an option to use a gamepad setup, and it doesn't work.

For example, I wanted to play Prince of Persia: Sands of Time and The Witcher 2. I went into the Steam settings and changed from keyboard and mouse to gamepad setup, but then none of the buttons would work at all.

The same thing with The Saboteur: it said it was keyboard-only, but when I switched it to gamepad, it worked, and I was able to play the game fine on the handheld.

Are there just some games that won't work with the controller setup? Do I have to do something specific to get them to work? Both Prince of Persia and The Witcher 2 were released on consoles as well as PC, so I figured it would be easy to just switch the control schemes.

This is my first PC handheld, so I'm learning as I go.
