The 9th generation of the Lenovo Thinkpad X1 2-in-1 (formely X1 Yoga) is an Intel based 2-in-1 laptop with a 14 inch touchscreen introduced in 2024. The laptop screen can be folded over transforming the device in a tablet like tool while also including a stylus as an extra form of input. It uses the Intel Iris Xe graphic card and the 14th generation of Intel processors. One of the main changes is that the pen is not stored inside the housing but instead outside fixed with a magnet.

Webcam

OLED displays and those with integrated privacy shutters are using MIPI webcams (IPU6) which do not work out of the box as of writing.

The webcams in FHD displays (glossy/matte) work out of the box.

Brightness OLED Screen

Unlike previous OLED panels, the value written in /sys/class/backlight/intel_backlight/brightness defines the screen brightness. For the OLED version the maximum value is 400.

Performance modes

Lenovo supports 'platform-profiles', which can either greatly improve performance and throttling, or battery life and thermals. The default mode is "balanced" however users can switch between these modes using keyboard shortcuts:

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

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

# cat /sys/firmware/acpi/platform_profile

The performance mode may also be queried and set using powerprofilesctl from power-profiles-daemon. See CPU frequency scaling#Userspace tools.
