Firmware (e.g. bios and peripherals)
As of writing, the current BIOS version is 1.43. By visiting the downloads section (T470) an ISO can be downloaded and burned to disk which will perform the update from Lenovo. Or extracted and copied on a USB Stick.
Kernel and hardware support
Hardware video acceleration with Kaby Lake seems to work fine via va-api.
As noted in Intel graphics, the xf86-video-intel driver seems to cause more issue than the builtin modesetting
Xorg driver.
Works fine without the intel driver (on a Skylake configuration).
suspend-resume results in the fan holding at 100% without ever spinning down. This is being tracked on the kernel bugtracker. The issue seems to be resolved by BIOS 1.43.
138a:0097 will hopefully be supported as part of Validity90.
Screen backlight
Without the intel
driver (xf86-video-intel, neither xbacklight
or xrandr
brightness control are working.
It is possible that, with the good acpi_*
kernel parameters, the backlight related keys do their job.
Other workaround exists, such as described on this post or in the wiki acpid#Enabling backlight control.
Using the acpilightAUR package as a xbacklight
replacement works well.
You can also check this repository] as a base to add the ACPI rules to call xbacklight
when backlight keys are pressed.
Thunderbolt 3
With the latest kernel (4.12.12 as of writing), the Alpine Ridge thunderbolt 3 controller is recognized without any additional configuration. Using a generic thunderbolt 3 to HDMI + USB3 hub works out of the box (the HDMI output is recognized by xrandr as DP-1 output).
UEFI boot
After configuring the BIOS setup to allow UEFI boot (either UEFI only or both), it works flawlessly.

T470 model 20JN
Quite specific model, comes with a 6th generation Intel processor (Skylake) instead of a Kaby Lake like most T470 models. Output of lspci and lsusb with kernel 4.12.12-1.
