Kernel issues

I recommend using Ubuntu 16.04.3 or later to avoid most of the following issues.

If you try using 16.04.1 or earlier, you should use the following command to install the HWE kernel after installation (see this document for more details):

sudo apt-get install --install-recommends linux-generic-hwe-16.04 xserver-xorg-hwe-16.04

下記の問題が起きる可能性があるので、基本的には公式の 16.04.3 を使ったほうがよい。Ubuntu Japanese Team が提供する日本語 Remix リリースは無印の 16.04 であることに注意。特にイーサネットが使えない問題が面倒だが、このページを参考に4.4 より新しいバージョンのカーネルを USB メモリなどで用意しておくことでも対処できる。

Wifi and Eithernet problem

Ubuntu 16.04 with Linux kernel 4.4 can't recognize wifi and ethernet device on T470s. We can manually install a more recent kernel (such as 4.8) after installation (via USB drive) to solve the issue.

sudo dpkg -i linux-headers-4.8*.deb linux-image-4.8*.deb

NVMe support

The Linux kernel earlier than 4.11 can't handle power saving of NVMe devices properly. Andy Lutomirski's patch to solve the issue is mereged in 4.10.0-14.16 in Ubuntu and available in the latest HWE Stack for 16.04.

Bluetooth

[ubuntu] Intel 8265 Dual-band Wireless Bluetooth Drivers Failing to Load

It is also resolved in the latest HWE kernel.

Issues during installation

Disable Secure Boot

Install third-party software for graphics and Wi-Fi hardware, Flash, MP3 and other media

Summary: The following message displayed at startup is unavoidable if you want to use third-party driver, such as NVIDIA graphics driver and VirtualBox driver, and NOT a major issue in most cases.

Booting in insecure mode

Can't unlock LUKS encrypted drive

Encrypt the new Ubuntu installation for security

Summary: Configure the kernel parameter to change from splash to nosplash when starting the kernel.

Thunderbolt 3 Dock

ThinkPad Thunderbolt 3 Dock

BIOS setting

If ThinkPad doesn't recognize your mouse and keyboard connected to the dock when reconnect the Thunderbolt 3 cable, changing Security Level of the Thunderbolt 3 setting to No Security would help.

Suspending

Unplug USB-C cable before suspending ThinkPad is recommended because it, unfortunatelly, sometimes crash in resuming.

Ethernet on the dock

4.10 kernel doesn't support ethernet on the dock. You must use 4.13 instead.
