Fingerprint reader stops working on suspend #115

Open kozross opened 2 years ago

kozross commented 2 years ago

I've set up python-validity according to the instructions for my distro (Arch Linux) and enrolled a fingerprint successfully. This works, but only until I first suspend. Once this happens, upon waking, I can no longer log in via fingerprint scan (the option isn't even offered), and when I check the status of fprintd.service, I get this:

[koz@Emi ~]$ systemctl status fprintd.service
○ fprintd.service - Fingerprint Authentication Daemon
     Loaded: error (Reason: Unit fprintd.service failed to load properly, please adjust/correct and reload service manager: File exists)
     Active: inactive (dead)
       Docs: man:fprintd(1)

Mar 17 16:45:57 Emi systemd[1]: fprintd.service: Two services allocated for the same bus name net.reactivated.Fprint, refusing operation.

Enabling the suspend-related services does not help. I do not have any other fprintd-related anything installed: only what was required for the AUR package. I'm using a ThinkPad T580, with python-validity 0.12-5 according to pacman -Qs. My DE is GNOME.

I had the same problem on Fedora 36. Try disable and enable again open-fprintd-resume and open-fprintd-suspend services.

I have the same issue on the Thinkpad Carbon X1 gen6, but this solution does not work for me. Any other tips? fprintd.service unable to start

Update: the trick abobe solved it for me
