Fixing Thermal Throttling on Thinkpad P1 and X1 Extreme - Linux Edition

Lenovo messed up with the X1E and P1 Gen 1 versions (and maybe later generations) in that the system boots with a thermal limit (aka Tjunction or tjmax) set to 82C (some report 80C). What this means is that regardless of power draw or under-volting settings, when your CPU hits 82C, it will drop the frequency down to the "Configurable TDP-down" frequency, or even lower. It will also may limits the system power draw.

lsusb lists the fingerprint reader in the x240 as follows:

Bus 002 Device 003: ID 138a:0017 Validity Sensors, Inc.

There exists experimental driver support for this in a fork of libfprint for vfs5011 sensors, however you'll need to compile the driver yourself. To get the fingerprint sensor to work for lightdm login, su etc, follow these steps.

1. Install fingerprint-gui:

   sudo add-apt-repository ppa:fingerprint/fingerprint-gui
