Yes that is with the intel card running. The radeon is in the external media
dock.

Yes, I saw somewhere that it may be trying to pipe it through the external
card. I will try that but it should work with just the intel card running?

Could you tell me which file to look for so I can change the perrmissions? I
think actually that the card id is too new. looking at the Authentec site it
says that my card (id:  08ff:168f) is the same as 08ff:1680 and 1660

http://support.authentec.com/KnowledgeBase/KBview/tabid/843/ArticleId/299/Identifying-your-Fingerprint-Sensor-Model.aspx

Where fingerprint-gui site says they only support the 08ff:1600 here:
https://launchpad.net/~fingerprint/+archive/fingerprint-gui

Maybe I need to put in a bug report? Or have you gotten it working?

Ok, So I can re-encrypt everything and I should be able to get it working?

Unfortunately, none of this works WITH the intel card. Also, one other
thing, I am running the latest MESA stack (compiled). Here is the output
from glxinfo:

$ glxinfo | grep version
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
OpenGL version string: 2.1 Mesa 7.12-devel
OpenGL shading language version string: 1.20

Any other help is appreciated.

Thanks,
Rob

P.S. Where are you in Japan? I lived there for many years.
