一直对这个鸡肋设备很不感冒，直到在Ubuntu下加上了指纹识别。安装很简单，效果很强筋。不只是开机可以用指纹，任何时候，只要系统要求输入root user密码，你都可以刷指纹。Are you getting me？在Terminal下用sudo可以刷，在Gnome下执行高级任务可以刷，真是太爽了。
在ubuntu 8.04下软件已经在库里了
sudo apt-get install libpam-thinkfinger thinkfinger-tools
把/etc/pam.d/common-auth改一下，这样只要要密码的时候都可以刷，哈哈
# /etc/pam.d/common-auth - authentication settings common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of the authentication modules that define
# the central authentication scheme for use on the system
# (e.g., /etc/shadow, LDAP, Kerberos, etc.). The default is to use the
# traditional Unix authentication mechanisms.
#
auth sufficient pam_thinkfinger.so
auth required pam_unix.so try_first_pass nullok_secure
再把你的指纹存一下，要刷三次
sudo tf-tool --acquire
然后把指纹关联一下
sudo tf-tool --add-user 用户名
然后启用（我没运行就能用了）
$ sudo /usr/lib/pam-thinkfinger/pam-thinkfinger-enable
然后就爽去吧
