Linux

Hello people,

I have been experiencing some trouble with my keyboard lately since moving from Windows to Linux and have yet to find a proper solution. I'm running Fedora 44 (KDE Plasma Desktop), specifically:

Operating System: Fedora Linux 44
KDE Plasma Version: 6.7.1
KDE Frameworks Version: 6.27.0
Qt Version: 6.11.1
Kernel Version: 7.0.13-200.fc44.x86_64 (64-bit)
Graphics Platform: Wayland

The keyboard is a NuPhy Halo75 (ANSI-US layout). It has a toggle to switch between Windows and Mac mode/layout and media keys on the function row; I want the function keys to be function keys by default and media keys when pressing Fn. On Windows, I was using the "US International" layout (primarily for Ä/Ö/Ü on Alt+Q/Y/P and € on Alt+5).

Now, sadly, on Linux, with the keyboard toggle set to Windows and either the "English (US, intl., with dead keys)" or "English (US, intl., AltGr. Unicode combining)" layout enabled, I can type my precious umlauts etc. perfectly fine, but the function keys always act like media keys, no matter what else I press, and I have not found any way to change that behavior. With the toggle set to Mac, the function keys work fine (as do the media keys with Fn), but I can no longer type umlauts (and what even am I without my umlauts). I enabled the "Alt is swapped with Win" keyboard option, since those are swapped on the Mac layout. From the keyboard preview, the key presses seem to be mapped correctly (left and right alt show up as "Meta L/Alt L" and "Meta R/Alt R", respectively, the Windows key shows up as "Super L").

I'm probably just missing some option or something, but I've looked everywhere I could think of (and, considering I am quite new to Linux/KDE, that isn't too many places) without luck. My web searches didn't really turn up anything useful either. So, if anyone has an idea or knows where to look and what to change, that would be highly appreciated! I hope my description of what I'm looking for is understandable.

I apologize for the somewhat long-ish post, but if you read this far, thank you :)
