Fingerprint scanner: Difference between revisions
fprintd-enroll doesn't need to (and shouldn't) be run as root |
don't encourage enabling fprintd service at boot, this goes against upstream wishes and can lead to possible hardware damage, as many fingerprint scanners are not intended to remain "active" for a long time. it is more appropriate for the service to activate via dbus when it is needed, to greatly reduce this risk. |
