Mix and match login managers and desktop environments (lemmy.world)

Hi, I think I've run out of keywords to hit Google with, so it's time to ask for help.

I'm running Fedora on my Framework 16, which is domain joined to my home lab Active Directory. Overall I'm pretty happy with KDE, but SDDM is proving to be rather bothersome (it's not a huge fan of my domain account, and constantly forces me to enter my creds in the other user free form, which prevents me from using my fingerprint sensor to login). For grins, I tried out the GDM display manager and was able to both pick my account from the list of users and use my fingerprint to log in. That said, I'm not a particularly huge fan of the GNOME look and feel.

So, I was wondering if it would be possible to use just the GDM login prompt, but have it feed into KDE desktop and if so what I'd need to tinker with to configure it.

(I feel like it should theoretically be possible, but it's not strictly a deal breaker- worst case the next Fedora update in April is supposed to be replacing SDDM with a new fork)

I'm pretty sure most login managers have a drop-down hidden somewhere where you can select what desktop manager it launches once you log in.

Framework 13 here, KDE Fedora user too. It literally never occurred to me that I could use the fingerprint to log in! Commenting so that whoever answers you can make my day too.

Good news! If you have a regular local account, this should just work for you. If you open the user tab in the settings menu and pick your account, you should have an option to configure the fingerprint reader (framework docs).

This doesn't quite work for me, because my account doesn't show up in the users list to configure (I think it's because domain accounts tend to have higher UID's than "normal", so they get filtered out, but I'm less sure what part of KDE controls that to dig into it).

Could anyone explain to me how to set it up so you can login using your fingerprint? I'm using Bazzite, which is basically just Fedora KDE. Right now I can only do that on the lock screen, but not the login. I haven't been able to figure it out, but OC's comment reminded me about it and I figured I should ask just in case someone happens to know.
