To have EAC work on Linux you need to set a toggle during build, some developers just refuse to do that so EAC won’t work. There are also companies that are just plain hostile to Linux, because that’s where the hackers live or some bullshit.

Fingerprint reader does not work as it does on other OS. You can log in, but the key ring stays locked causing programs in user space to break, so I always need to log in with my password before it works. The fingerprint prompt blocks input access so you can’t type in the password and you have to wait for it to time out, also the prompt does not always appear. And the developers actively refuse to fix the not unlocking the keyring because it’s “not secure”.

Fingerprint scanners for both Windows and macOS, you can log in and it just works.

Second thing is the still broken bluetooth drivers on Debian based distro’s where it randomly just fails. No such issues on Fedora (KDE) as of yet, but I use both.
