Lenovo ThinkPad T440p

Introduction

Running Linux on the Lenovo ThinkPad T440p laptop should be no problem. I have Slackware64-14.1 on my Lenovo ThinkPad T440p, and basically everything works.

Notes

The Lenovo ThinkPad T440p is my constant companion. It's my work machine, and used for pretty much anything else too. I don't like the “clickpad” with no hardware buttons, but a tweak found on the Linux-Thinkpad mailing list (posted by Ted T'so in February 2014) made it usable (albeit still not ideal.) Note that's just a hardware design issue, not anything to do with running Linux or not.

Summary

Lenovo ThinkPad T440p works fine with Linux here. I'm a professional sysadmin, but I suspect anyone would do well enough with a recent enough distro. My Slackware64-14.1 shipped with a 3.10 kernel, and the iwlwifi.ko 802.11 driver did not work out of the box. I compiled a custom kernel to make it work.

does anyone figured out how to configure adaptive backlight (ie to follow lightning sensor, not webcam)?

The device works very well for me although there have been some issues at start mainly related to the docking station - the external display was not working at all but after some firmware upgrades it seems to be okay. Currently I try to resolve some issue with webcam but that may be only temporary issue.
