Hello, I am relatively new at Linux and started using nixOS on a new laptop. My laptop has a fingerprint sensor that works absolutely fine with plasma but not at all with sddm unless I login first at which point it starts a fingerprint timeout and it will login if I use it or after the timeout has ended. I’ve been trying to get it to auto login with my fingerprint without the need for a password.
the reason I specify nixos is because I’ve looked online for a while and have found possible solutions related to systemd but nixos makes most root files read only so that option is out the window. I would give a link if I could remember where I found it but that was a few weeks ago…
I assume all that’s needed to duplicate the issue is use a fresh install of Nixos (KDE Plasma obviously) and enable fprintd in the config. but I am on the unstable channel and you might have to upgrade to plamsa6. And apparently I can’t include links in this post so… search “nixos plasma6 upgrade” and it should be the first link to NixOS Discourse
Any help would be appreciated, and I’m sorry I don’t have more detail as to what I’ve tried. Last time I tried to fix this was two weeks ago.
