Rog Ally's controls not registering

I have the mod along with all the needed Fabric stuff downloaded, and the mod shows in the settings under Controls. No matter whenever my Rog Ally is connected to a mouse and keyboard or not, and no matter the mode it is in, in the settings it still says No Controllers Detected even if I've just used the joysticks and buttons to navigate to that screen.

I've got Bazzite installed if that makes any difference, so trying to do this on Linux but I've made sure my kernel is up to date as well as java and all that. I've tried to look this up in the wiki, but all it says is "My controller is not detected: If your controller does not show up on the controller list, this is the section for you." and no actual solutions or fixes.

Start by reproducing the controller-detection problem on a ROG Ally running Bazzite, with and without an attached mouse and keyboard, and in each reported mode. Check whether joystick and button input reaches the controller list shown under Controls. Done means the ROG Ally controller is detected and appears in that list.
