Here’s more on my experiences with Ubuntu on my Dell Latitude D830 laptop.
I tried to get the fingerprint reader to work so that I’d be able to authenticate with my fingerprint. The Dell website mentioned that it is a UPEK fingerprint reader, so I googled for it. It turns out that Hardy has packages for it!
I installed the following packages:
After I rebooted I could run the tf-tool. I guess I could have done:
sudo tf-tool --acquire /etc/pam_thinkfinger/myusername.bir
Instead I did
sudo cp .thinkfinger.bir /etc/pam_thinkfinger/myusername.bir
Then I edited
/etc/pam.d/common-auth and added pam_thinkfinger.so as authentication module and modified the one existing line:
auth sufficient pam_thinkfinger.so
auth required pam_unix.so try_first_pass nullok_secure
Voilá! It worked! I can now just swipe my finger instead of typing, both when I login as well as when I do a sudo. First I thought that it doesn’t work with gksudo, but then I discovered that it is working, just the prompt is (sometimes) wrong and just says “Password”. It is accepting the finger – but obviously I did it wrong when I tried first.
And after I had done all that I discovered that there is actually a page in the Ubuntu wiki that explains it. Some things are a little outdated though…
