The ThinkPad X1 Extreme is a thin-and-light 15.6" workstation/multimedia laptop from Lenovo's 2018 ThinkPad X lineup.
This page specifically concerns the specifics of running Arch Linux on this laptop. See Laptop for generic laptop-related information, or ThinkPad for other ThinkPad laptops. The Ubuntu certification page may also be useful.

Despite not being strictly required for an Arch Linux install, a BIOS update is strongly recommended for general use of the laptop - the initial 1.13 version devices seem to ship with contains multiple bugs that can result in bricking the laptop: Reddit thread discussing the issue; another Reddit thread discussing a different bricking issue.
The latest version, v1.24, is highly recommended. All information on this page generally assumes the latest BIOS unless explicitly stated.
After installing Bumblebee, the HDMI port works after modifying the following files, rebooting, and executing
intel-virtual-output -f from an X server running on the iGPU. See Bumblebee#Output wired to the NVIDIA chip for details.

While optimus-manager requires logging out to switch graphics, it provides better performance and more stable external display support. The following configuration has been found to work well:
[intel] driver=intel modeset=yes [nvidia] modeset=yes [optimus] switching=bbswitch
Using external graphics exclusively
Works fine with the default configuration produced by
nvidia-xconfig, including HDMI output.
Thunderbolt works out of the box (tested with ThinkPad Thunderbolt 3 Dock); see Thunderbolt for details on security.
The fan on the right side of the laptop can be controlled by thinkpad_acpi. It seems that the fan on the left side can't be controlled yet; see this Nvidia forum post. If noise is an issue, the fan can be turned off manually by unplugging it from the motherboard, or the dust mesh can be removed.
The touchpad experience can be greatly improved by enabling "intertouch" as hinted by kernel messages. This can be done by either adding
psmouse.synaptics_intertouch=1 to the kernel command line or by creating a modprobe entry like:
options psmouse synaptics_intertouch=1
The webcam works out of the box, though it reports a completely black image instead of the "disconnected" placeholder when the protective slider is closed.
Everything else works correctly out of the box.
Dolby Atmos Effect on Linux
In order to get the same speaker sound quality/effect as on Dolby Atmos with Windows install & configure PulseAudio and . You can then download the Dolby Atmos preset from JackHack96's Github and enable it in the "Convolver" tab of the PulseEffects GUI.
Battery charge thresholds
Battery charging thresholds can be configured via sysfs nodes
/sys/class/power_supply/BAT0/charge_stop_threshold, or using TLP.
CPU throttling workaround
A stress test usingAUR indicates that the CPU is limited to 38W/80C, resulting in maximum sustained frequency of around 2850 MHz on i7-8750H under heavy loads.
This can be worked around by using
intel-undervolt (see below). It raises the power limit to 44W, which, combined with the
performance CPU frequency scaling governor, allows the CPU to run at 3100 MHz with the temperature of 95C.
Undervolting the CPU/Intel GPU works well with intel-undervolt. Generally -150mV seems to be a safe choice on the i7-8750H and i7-8850H CPUs, but your mileage may vary.
The effects of undervolting on system stability will vary depending on individual hardware (a.k.a. "the silicon lottery").
