Lenovo Thinkpad X260
The Lenovo ThinkPad X260 is the successor to the Lenovo ThinkPad X240 and Lenovo ThinkPad X250. Major differences include the removal of VGA, removal of the SATA channel in the M.2 slots, and end of the 400nit screen option. New in this gen is the addition of HDMI, DDR4 memory, and improved battery life.
Some X260's come with vfs (Validity Sensors) fingerprint readers. If this is the case then you will need to additionally install fprint for details.AUR, along with fprintd. See
