[Solved]Yubikey not unlocking cinnamon-screensaver

Post by zenadm1n »

This is now resolved but Google is still not showing me the solution so I'm documenting here in case it gets indexed.

After an upgrade to LMDE 6 (faye) the previous fix to enable Yubikey HMAC-SHA1 unlock of the cinnamon-screensaver was no longer working. I was dropping to a terminal and running cinnamon-unlock-desktop in order to get back in after hibernation. After a few days I had dozens of the following process running after I checked btop, "cinnamon-screensaver-pam-helper". So that's the new program that needs permission to read the Yubikey when I'm not logged in. It was continuing to run every time I bypassed it. Like the previous Yubikey screensaver fixes use "setcap"

Code: Select all

sudo setcap cap_dac_read_search+ep /usr/lib/x86_64-linux-gnu/cinnamon-screensaver/cinnamon-screensaver-pam-helper
To remove the permission on any previous screensaver helper use "setcap -r filename".
