The Lenovo Yoga Duet 7 13IML05 is a 2-in-1 convertible laptop introduced in late 2019. It features a 13" 16:10 2160x1350 WQHD multi-touch touchscreen, Intel 10th-gen Comet Lake Core processors and integrated Intel UHD 620 graphics. Its detachable keyboard/touchpad unit features Bluetooth connectivity and may be used detached from the main tablet unit.

To ensure you have this version, install the package dmidecode and run: 

# dmidecode -t system | grep Version
       Version: Yoga Duet 7 13IML05

Firmware

The BIOS is accessed by repeatedly pressing the F2 key during system boot when the display powers up and before the Lenovo logo is displayed on the screen.

The boot menu to choose the boot device is accessed by repeatedly pressing the F12 key during system boot when the display powers up and before the Lenovo logo is displayed on the screen.

Accessibility

The BIOS user interface is graphical. An option to switch to a text-based GUI is not provided. However, the options may be selected with the arrow keys and the values changed with the F5 and F6 keys.

The speakers do not work out of the box (see below), so in particular speech-aided installation is not possible.

Suspend / Standby

The system supports the traditional S3 Sleep power state where all hardware components are turned off except for the RAM, as well as a newer software-based Modern Standby (S0iX). One possible benefit to the Modern Standby sleep state is faster wake up time, and one possible drawback is increased power usage.

To check which standby mode is currently active on your system: 

# cat /sys/power/mem_sleep
       [s2idle] deep

s2idle means Modern Standby, deep means S3 Sleep.

Enabling S3 Sleep

To enable S3 Sleep instead of Modern Standby, add mem_sleep_default=deep to the kernel options.

Audio

The speakers and the headphones connector work out of the box with Linux kernels up to and including 5.4.88.

Due to this bug, a kernel patch is required to have working audio on newer kernels.

The kernel source file /sound/pci/hda/patch_realtek.c needs to be patched.

Search for this line: 

	SND_PCI_QUIRK(0x17aa, 0x3818, "Lenovo C940", ALC298_FIXUP_LENOVO_SPK_VOLUME),

And replace it with the following line: 

	SND_PCI_QUIRK(0x17aa, 0x3818, "Yoga Duet 7 13IML05", ALC287_FIXUP_YOGA7_14ITL_SPEAKERS),

Please refer to Kernel#Compilation and Kernel#Patching_packages for instructions on applying a kernel patch and compiling a custom kernel or kernel module.

In addition to the kernel patch, the Lenovo Yoga Duet 7 13IML05 requires additional firmware in order for the sound card to work. Install the alsa-firmware, sof-firmware, alsa-ucm-conf and alsa-tools packages and reboot to activate the firmware.

With the patched kernel and additional firmware, all audio components including the speakers, headphones and microphones work.

Enabling automatic screen rotation under GNOME and Wayland

Install the iio-sensor-proxy package. The screen will now automatically rotate and keyboard/touchpad input will be disabled when the keyboard/touchpad unit is folded back in tablet mode. If the screen does not rotate automatically, try running 

$ gsettings set org.gnome.settings-daemon.peripherals.touchscreen orientation-lock false

Alternatively, use Super+o to toggle lock state.

Note: GNOME 40 has a regression in the mutter package that prevents screen rotation from working. See https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1846 for more information.
