Which patch exactly do you need? I do not know it. I just know that the libfprint from gentoo does not work for my thinkpad, but when i install redhat, it miracuously works. from the redhat bugzilla entrys, it seems that one needs the two patches together. "0001-Rework-discover-code-for-drivers.patch" [1] is included to big parts. "0002-Implement-discover-methods-for-upeke2-and-upeksonly.patch" [2], too, in both versions I checked (0.4.0 and 0.5.0). [1] https://bugzilla.redhat.com/attachment.cgi?id=439239 [2] https://bugzilla.redhat.com/attachment.cgi?id=439240 the strange thing what happens on my t520 is the following: When I start fprint_demo, and try to record a fingerprint, the yellow light of the finger print scanner works and I'm asked to swipe my finger for six times. Even the swipes work. However, after the fifth swipe, I'm asked again to swipe my thinger on the printer. fprint_demo now says that the sixth swipe was completed, and then, it crashes. Fprint demo also says that my device would have no fingerprint intentification implemented. So, even if the recording of the fingerprints would work, fprint would say that I would not be able to verify my fingerprint. I have now installed fingerprint_gui in gentoo. And this program miracuously works for my t520. Even if there seems to be some bug too. When logging in, fingerprint_gui asks me to verify my fingerprint or to type in my password. if I now swipe my finger, then everything is fine. However, if I choose to type my passwort, then the led of the fingerprint scanner will stay on and shine until i restart my computer.... I also get a buggy fprint_demo, but that is unrelated to this bug. The patches have already been upstreamed long ago. My fingerprint reader (the same kind as is the subject of this bug) works fine. |
