Warning: Do not buy this laptop (says even Lenovo) with MIPI camera (listed by Lenovo as 'Computer Vision camera') (an only option with 2.8k OLED screen but also possible with IPS screens) which does not have open source drivers and will not just work in the coming few years.

Audio

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

Video

Fingerprint reader

The fingerprint reader works out of the box using fprintd. See Fprint.

Camera

The Gen10 Carbon X1 can be configured with one of two webcam setups:

FHD 1080p camera - tested and works;
MIPI "Computer Vision" - does not work, see this thread on the Lenovo Forums.

Mobile broadband

The Fibocom L860, Fibocom FM350-GL, and Quectel EM05-CE WWAN chips are currently available for this laptop. The Quectel EM05-CE chip should be operable out of the box on Linux. Use of the Fibocom L860 chip requires installing the external FCC unlocking tool, which is available with the thinkpad-l860-gl-fcc-unlock-bin^AUR package. Do note that the unlocking tool does not work in the US yet, however it has been promised that support for US sim cards will be available soon. Support for the Fibocom FM350-GL chip is still under development.

See Lenovo ThinkPad X1 Carbon (Gen 9)#Mobile broadband for details of what that operation looks like, however that laptop had the benefit of having the Qualcomm based Foxconn SDX55 available which does have an FCC unlock operation available for it. Attempting to put this chip in a 10th Gen laptop does not work as the "BIOS whitelist" only allows three chips listed above.

Powersaving

This laptop works nearly out of the box with tlp; however, the WWAN chip currently has issues with runtime power management and will prevent booting if runtime-pm is enabled for the device. To exclude it, modify the tlp configuration like:

/etc/tlp.conf

RUNTIME_PM_DENYLIST="08:00.0"

Performance modes

Lenovo supports 'platform-profiles' on newer kernels which can rather dramatically improve performance by decreasing throttling, or greatly improve battery life and thermals by lowering the CPU's power limit. These modes can result in over a 100% increase or decrease in CPU power draw. The default mode is "balanced" however users can switch between these modes using the following keyboard shortcuts:

Fn+l - Low-power mode
Fn+m - Balanced mode (aka Medium)
Fn+h - Performance mode (aka High)

These modes can also be selected automatically by using tlp and the PLATFORM_PROFILE_ON_AC/BAT configuration fields.

The currently active mode can be checked with the following command:

# cat /sys/firmware/acpi/platform_profile

Firmware

UEFI firmware and other device firmware is available through the Linux Vendor Firmware Service (LVFS), and can be installed using fwupd.

Secure boot works out of the box with custom keys from multiple tools, including sbctl.

Function Keys

In the firmware configuration it is possible to swap the Ctrl and Fn 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.

Key	Visible?¹	Marked?²	Effect
`Fn+Esc`	No	Yes	Toggles Fn lock
`Fn+F1`	Yes	Yes	`XF86AudioMute`
`Fn+F2`	Yes	Yes	`XF86AudioLowerVolume`
`Fn+F3`	Yes	Yes	`XF86AudioRaiseVolume`
`Fn+F4`	Yes	Yes	`XF86AudioMicMute`
`Fn+F5`	Yes	Yes	`XF86MonBrightnessDown`
`Fn+F6`	Yes	Yes	`XF86MonBrightnessUp`
`Fn+F7`	Yes	Yes	`XF86Display`

`Fn+Space`	Yes	Yes	`XF86SelectiveScreenshot`
`Fn+4`	Yes	No	`XF86Sleep`
`Fn+Left`	Yes	No	`Home`
`Fn+Right`	Yes	No	`End`
`Fn+l`	No	No	Switch to low power mode
`Fn+m`	No	No	Switch to balanced/medium power mode
`Fn+h`	No	No	Switch to performance/high power mode

The key is visible to xev and similar tools. Wayland-only indicates the code can only be seen from a Wayland session.
The physical key has a symbol on it, which describes its function.

Accessibility

This laptop features a UEFI interface that is driven with a mouse; however, this interface can be disabled in favor of a traditional keyboard interface which is more accessible to use. Blind users might need to request help from a sighted person in order to make this change initially, but once changed the interface is far more easily navigable.

The boot device can be changed out of the box without needing to access the UEFI menu during boot by hitting F12, though the menu is initially on a 10 second timer so it might be necessary to input an UP or DOWN after the menu loads if the user is using a screen reader or something else which might take time in order to provide the user feedback on which option to select.
