Gentoo on Spectre x360

A couple of weeks ago, my laptop, a 4 years old ultrabook, stopped working because of a bus problem. Instead of asking the manufacturer to fix it, I took the decision of buying a new laptop.

At the end of some research (and some misadventures with another manufacter) , I opted for a HP Spectre x360 4110nl. It is a gorgeous machine.

First things, first. I disabled the safe boot and booted the Gentoo Live DVD. Everything was working  out of the box, even the touchscreen.

So I installed it from stage3, but I did not compiled my own kernel. Instead, I used genkernel. It was my first time with genkernel, I usually compile it manually.


Here is the list of hardware and the output of lspci

To correctly use the video card you need to include the firmware into the kernel. Look at the Wiki page about Intel.For this model I needed to add

CONFIG_EXTRA_FIRMWARE=”i915/skl_dmc_ver1.bin i915/skl_guc_ver4.bin”


Worked out of the box. Just remember to add the wpa_supplicant service to rc.


To enable to touchscreen I needed to re-compile the kernel with CONFIG_HID_MULTITOUCH.

There are still some feature missing, that I need to sort out:

  • Double tap
  • Auto rotation adjustment
  • Disabling keyboard when in tablet mode
  • OS virtual keyboard
