Audio
This laptop requires ALSA firmware (i.e. the sof-firmware package needs to be installed) in order for the soundcard to work.
Video
See Lenovo ThinkPad X1 Carbon (Gen 9)#Video.
This machine uses OLED 2880*1800 @120Hz monitor. Users should apply HiDPI settings and Scaled by System is not recommended, as it will blur the programs.
Fingerprint reader
The fingerprint reader works out of the box using fprintd. See Fprint.
Function Keys
In the firmware configuration it is possible to swap the Ctrl
and Fn
keys.
Similar to Lenovo ThinkPad X1 Carbon (Gen 10)#Function_Keys,some of the function keys have keycodes with values that are too high to use in X, which truncates values past 248. In wayland, these keys might be difficult to map but can be doable manually using the in your desktop environment by specifying the XF86 keysym by hand from the table below. For example, in Gnome you can use dconf-editor to modify entries in /org/gnome/settings-daemon/plugins/media-keys/
and other settings locations.

Mobile broadband
For now only China veriants have WWAN module preinstalled, with Quectel EM05-CN.
From this generation, WWAN modules are detected with lsusb(8)
Using this module does not requires to have fcc unlocked and can be used directly with modemmanager.
The only problem to this module is power failure after waking up, and may takes some time to make it connected again.
Firmware
Similar to Lenovo ThinkPad X1 Carbon (Gen 10)#Firmware, UEFI firmware and other device firmware is available through the Linux Vendor Firmware Service (LVFS), and can be installed using fwupd. Updates to the UEFI firmware include updates to the Intel Management Engine, so they may fail altogether if IME is disabled on the UEFI settings. A workaround for this is to temporarily enable IME, upgrade the firmware with fwupd, and disable IME after that.
Secure boot works out of the box with custom keys from multiple tools, including sbctl.
