I recently upgraded my Thinkpad X61s to Linux Mint 17 from version 16 which I had before. On Mint 16, fingerprint login worked fine after installing and setting up fingerprint-gui.
However, with Mint 17, I cannot log in with MDM.
Everything else seems to work though: It shows me the message to swype my finger, then it shows "OK" - but MDM displays the message that a false password has been entered.
In cinnamon however, after logging in with my password, sudo and gksu work fine with the fingerprint reader.
Here's an excerpt from /var/log/auth.log, which I think contains the relevant information:
Code: Select all

Please help me with that!
Thanks & best regards!
