Semi working build. Polkit authentication agent missing?
AreYouLoco opened this issue · 3 comments
Describe the bug
I have added:
auth sufficient pam_fingerprint-gui.so to /etc/pam.d/su
but pam_fingerprint-gui.so is non existant on my system.
To Reproduce
I've successfully build qt5 tree on debian bullseye (testing) and fingerprint-gui is enrolling fingerprints and verifying it. But I cannot make it work with lightdm login and sudo/su.
Expected behavior
Fingerprint reader would activate during login and su/sudo requests.
Screenshots
Desktop (please complete the following information):
- OS: Debian Bullseye (testing)
- QT5
- Version: debian-testing:sc:20200712
- Hardware: Thinkpad T420, 147e:2016 Upek Biometric Touchchip/Touchstrip Fingerprint Sensor
Additional context
$ /usr/local/lib/fingerprint-gui/fingerprint-polkit-agent -d
New PolkitAgentListener 0x558985c6ba00
Adding new listener PolkitQt1::Agent::Listener(0x7ffe64566c80) for 0x558985c6ba00

Removing listener PolkitQt1::Agent::Listener(0x7ffe64566c80)
Any suggestions?
Ok I compiled again and it seems like libpam_fingerprint-gui.so is in /usr/local/lib/security/libpam_fingerprint-gui.so. Why doesn't it work? Wrong directory?
I've added udev rules from here https://aur.archlinux.org/fingerprint-gui.git and removed temporarily polkit-gnome-authentication-agent-1.desktop and polkit-mate-authentication-agent-1.desktop from /etc/xdg/autostart/ and rebooted but still no luck...
EDIT:
Removing files from /etc/xdg/autostart lets me start:
$ /usr/local/lib/fingerprint-gui/fingerprint-polkit-agent -d
New PolkitAgentListener 0x55f16640a800
Adding new listener PolkitQt1::Agent::Listener(0x7ffdd45b0ef0) for 0x55f16640a800
SOLVED! I managed to make it work with fprintd. Closing.
