Yes the official wireless adapter from Microsoft. Xpadneo makes it work with Linux, you can fully use the controller with the original wireless adapter. Only audio is not working

It works very well with the wireless adapter, see this comment for a great long explanation

I prefer KDE since a started with Linux

Fedora 41 works with nvidia and secure boot. For your controller take a look at Xpadneo works fine with the wireless controller ☺️

Heliboard is a fork of openboard. Openboard is not maintained anymore. No updates for years

I am using Heliboard for a long time now and I am very happy with it 😌

2 years and still no word suggestions, they are coming with 0.5 but when?

I think Heliboard is a better choice, it is privacy focused and has the same features including wird suggestions.
