ThinkPad X1 Extreme Gen 4i

Audio

This laptop requires ALSA firmware (i.e. the sof-firmware package needs to be installed) in order for the soundcard to work.

Fingerprint Sensor

Works fine, the packages fprintd and libfprint are required.

Suspend

For suspend to work properly, you must go to Config > Power > Sleep state, and set to Linux S3.

Note: Under System Firmware 0.1.19 The sleep state Windows and Linux does not seem to be fully effective. For instance, if you close the lid of the laptop while the fans are running the fans will continue to run even though the CPU suspends.

Video

If you want Nouveau and Wayland to work, you must set Config > Display > Graphics Device to Discrete Graphics. Unfortunately this will make the laptop very hot and consume lots of power! Also, sometimes the graphics get glitchy.

Following PRIME#Open-source drivers did not work for the author in X11. Following PRIME#Closed-source drivers works fine.

Either way, consider installing zcfan^AUR or thinkfan^AUR.

KMS

If you use the closed source NVIDIA driver, see NVIDIA#Early loading.

Touchpad

Touchpad might not be recognized when acpi_osi=Linux is set.

Wifi

If you found Wifi is slow when enabling power save mode for iwlwifi, try switch to use iwd and optionally setup iwd as backend for NM NetworkManager.
