02:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)

Intel Corporation Wireless 8265 / 8275 does not work out of the box.
Look for the iwlwifi firmware in the /lib/firmware directory.

user $ls /lib/firmware | grep iwlwifi-8265
iwlwifi-8265-21.ucode
iwlwifi-8265-22.ucode

Note
If the output is empty, install sys-kernel/linux-firmware or download the driver from here
Warning
Some had problems connecting to a 5GHz network with iwlwifi-8265-27.ucode firmware.[1]

For more information on iwlwifi configuration, see the iwlwifi wiki.

Video

NVIDIA Optimus

Configure according to NVIDIA/Optimus & the NVIDIA/nvidia-drivers articles.

Note
There is no need to add nvidia to the VIDEO_CARDS variable in /etc/portage/package.use

This is the necessary Xorg configuration:

FILE /etc/X11/xorg.conf.d/20-nvidia.conf
Section "Module"
    Load "modesetting"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "01:00:0"
    Option "AllowEmptyInitialConfiguration"
EndSection

Be sure to switch the OpenGL drivers before starting X:

root #eselect opengl set nvidia

Intel

See the intel page for up-to-date kernel parameter instructions.
Configure Xorg to use intel driver.

FILE /etc/portage/package.use/00video
*/* VIDEO_CARDS: -* intel i915

Rebuild changed packages.

root #emerge -DaquN @world

Emerge the dated Intel HD Graphics driver.

root #emerge -qan x11-drivers/xf86-video-intel

Configure Xorg file.

FILE /etc/X11/xorg.conf.d/10-intel.conf
Section "Device"
    Identifier "intel"
    Driver "intel"
EndSection
Warning
Be sure to keep the /etc/X11/xorg.conf.d/ directory clean! Do not have a configuration file for NVIDIA optimus & Intel HD Graphics

NVIDIA

First off, add nvidia to VIDEO_CARDS in /etc/portage/package.use

FILE /etc/portage/package.use/00video
*/* VIDEO_CARDS: -* intel i915 nvidia

Update influenced packages

root #emerge -DaquN @world

Follow the NVIDIA guide for a (mostly) complete configuration.

Important
Disable all Framebuffer devices except the EFI framebuffer. Others may interfere with the boot process, in which you'll may experience a boot freeze.[2].
Note
If you experience a GRUB freeze on boot, try rebooting using ctrl+alt+del and select UMA Graphics or Hybrid Graphics in the BIOS

Set the following kernel parameters to be able to use Discrete Graphics

KERNEL Linux 4.9.76-gentoo-r1
Device Drivers --->
    Graphics support --->
        Frame buffer Devices --->
            -*- Support for frame buffer devices --->
            [*] EFI-based Framebuffer Support

The following configuration enables brightness control, forces full composition pipeline to decrease screen tearing and forces a dpi of 96, which could otherwise give problems in your wm with varying glyph sizes.

FILE /etc/X11/xorg.conf.d/10-nvidia.conf
Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    Option "RegistryDwords" "EnableBrightnessControls=1"
EndSection

Section "Screen"
    Identifier "Screen0"
    Device "nvidia card"
    Monitor "Monitor0"
    Option "metamodes" "nvidia-auto-select +0+0 {ForceFullCompositionPipeline=On}"
EndSection

Section "Monitor"
	Identifier "Monitor0"
	Option "DPI" "96 x 96"
EndSection

Bluetooth

Follow the Bluetooth article on configuring and using Bluetooth.

HP 3D Driveguard

HP 3D Driveguard is a feature of HP laptops that turn off the hard drive when the laptop is falling. To enable HP 3D Driveguard, follow the instructions of the HPfall article.

Troubleshooting

External DisplayPort monitor does not work on PCIe(Thunderbolt 3) port

When using an adapter to connect a DisplayPort monitor to the PCIe port and the monitor does not get recognized, try:

  1. Make sure the adapter is not plugged into the PCIe port;
  2. Disconnect the DisplayPort cable from the adapter;
  3. Plug the adapter into the PCIe port;
  4. Connect the DisplayPort cable.

Now it should work!

NVIDIA brightness control

To enable brightness control, add this line to the conf file

FILE /etc/X11/xorg.conf.d/10-nvidia.conf
Section "Device"
    ...
    Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection

Screen tearing

As the browser is most frequently used: emerge www-client/firefox with USE variable hwaccel. It fixes 99% of smooth scrolling screen tearing. Really a game changer!

For other screen tearing problems, check out x11-misc/compton.

Keyboard layout

To set the keyboard layout to Dvorak Programmer

tty

For terminal:

FILE /etc/conf.d/keymaps
keymap="dvorak programmer"
...

Graphical

For X:

FILE /etc/X11/xorg.conf.d/40-keyboard.conf
Section "InputClass"
    Identifier "keyboard-all"
    Driver "evdev"
    Option "XkbLayout" "us"
    Option "XkbVariant" "dvp"
    MatchIsKeyboard "on"
EndSection

Unable to suspend with Nvidia driver

If you have trouble suspending while on Discrete Graphics, switch to sys-auth/consolekit instead of sys-auth/elogind. This replaces suspend for pm-suspend and should fix the suspend issue. More instructions on switching at Suspend and hibernate.
