Module not being called in mate lockscreen #28
Comments
You seem to have a talent for discovering rare bugs ;) I'm quite lost on this one, it might be handling sessions incorrectly? Does |
Also, could you take a look at the last lines in |
sudo -i works fine, but here's auth.log when I log in from the screensaver: Fascinating - I wonder if my user is trying to call the module? |
Changed permissions on pam.py to 750, but then when I went to unlock from screensaver saw this in auth.log:Apr 26 18:01:16 bartlet /lib/security/howdy/pam.py[17152]: File "/lib/security/howdy/pam.py", line 53, in pam_sm_authenticate |
Both should be impossible, what does your config.ini look like? |
So I changed the permissions of the howdy directory to 755, then tried again. Now howdy runs, and the login window says I've been identified, but then it still won't let me in without a password. auth.log: |
For anyone having the same issue: @arifeinberg has opened a ticked in the PAM library here. |
So I have a workaround. Please note I'm using Cinnamon Screensaver (should work on Mate too). First as you said: Then: It's crashing when sending the confirmation message, so disabling it makes the trick. :) |
Thanks so much for figuring this out! I'll add it to the FAQ if i ever get around to writing it. |
I ran into this issue. The |
Can confirm this works on Cinnamon. |
This does not work on Fedora release 32 (Rawhide) Mate 1.22.3 sudo works, LightDM works, but not the mate lockscreen. I tried making /lib64/security/howdy 0775, but it doesn't work. I've got no /var/log/auth either. Any other ideas? |
Is this secure, to have these files world readable? |
Readable shouldn't be a big issue, but don't make it writable |
Can confirm making /lib/security/howdy/ world-readable solved an issue I was facing with Can this be the default? |
Hi, I got this issue with clearing all faces ( |
This problem appeared to me (Debian 10 + Mate). I believe a fix for cinnamon/mate would be good, the question is whether it is only in these environments (screensavers) that it happens. I documented this solution on the wiki¹ (common issues). Could we keep this issue open? The problem hasn't really been solved, the suggestions are just a temporary solution, right?

I'm running ubuntu-mate and I have howdy working normally when I sudo or login through lightdm, but when I lock my screen, I can only unlock with my password. The webcam never turns on when I get back to the lockscreen. My last computer (also ubuntu-mate) had a fingerprint reader with a similarly configured common-auth file, and the lock screen on that computer did take a fingerprint before asking for a password.
