Installation

Firmware

You will need some firmware from the Linux firmware package:

root #emerge --ask sys-kernel/linux-firmware

iwlwifi-8265-27.ucode
i915/kbl_dmc_ver1_01.bin (be sure to follow the Intel manual)

And add them space-separated in the kernel firmware selection:

KERNEL Enable firmware

Device Drivers  --->
    Generic Driver Options  --->
        (iwlwifi-8265-27.ucode i915/kbl_dmc_ver1_01.bin) External firmware blobs to build into the kernel binary
        (/lib/firmware) Firmware blobs root directory

Kernel

Touchpad

To set the touchpad (and keyboard knob) in the kernel, do the following.

KERNEL Enable support for touchpad and knob

Device Drivers  --->
     I2C support  ---> 
         I2C Hardware Bus support  --->
              <*> Synopsys DesignWare Platform
     Multifunction device drivers  --->
              <*> Intel Low Power Subsystem support in PCI mode
     HID support  --->
         Special HID drivers  --->
             <*> Alps HID device support
         I2C HID support  --->
             <*> HID over I2C transport layer

After that, the Synaptics article can be followed.

NOTE! Altering acpi_osi parameter may result in touchpad being not detected and as such, not working.

Nvidia dGPU and freeze on starting X with dGPU switched off by bbswitch

It may occour that Xorg freezes on start if prior to that dGPU was disabled using the bbswitch kernel module. The system may also randomely freeze after waking out of s2ram. Soluton to that is to enable CONFIG_ACPI_REV_OVERRIDE_POSSIBLE and add acpi_rev_override=5 to boot params. https://github.com/Bumblebee-Project/Bumblebee/issues/764#issuecomment-395869314
