I've got a ASUS Zenbook with Elan fingerprint reader. I can set up the fingerprint login successfully and it works for a couple of times. But after that it just stops recognising fingerprints. I wonder if anyone has managed to use the Elan fingerprint reader on a laptop successfully. The release notes for libfprint say that Elan is supported, but yes, it's new as the support only was introduced in the version before the previous.
