This repository serves as a central hub for software related to running GNU/Linux on Lenovo Yoga Book tablets (YB1-X91L/F, YB1-X90L/F).
Currently, it works on YB1-X91 models only (originally equipped with Windows OS). Hans de Goede (@jwrdegoede) has contributed significantly to running Linux on the Android variants of the tablet, but this has not been tested.
Most of the hardware is functional, with the following exceptions:
- Cameras
- LTE modem (in L modifications of the tablet)
- Keyboard vibration feedback
Most Linux patches have been mainlined, except for the sound drivers.
The Yoga Book tablet features a sensor keyboard, which essentially functions as a touchpad. To use it as a keyboard, a userspace 'driver' is utilized. Therefore, installing the OS without connecting a physical keyboard via an OTG hub can be challenging.
I personally use Debian, so the instructions below describe its installation. Ubuntu should also be compatible. For other distributions, you may need to download and build packages from the source.
Instructions are approximate, details may vary. Please create an issue if something goes wrong.
- Download an ISO image and write it to a USB flash drive (refer to Debian's official site for instructions).
- Connect a powered microUSB OTG hub to the tablet.
- Connect the USB flash drive and a keyboard to the hub.
- Power on the tablet while holding the Volume Up key.
- Select the USB drive in the boot menu.
- Install Debian as you normally would, and boot into the new system. The Gnome desktop is recommended because it supports screen rotation based on accelerometer data.
- Download the latest
.debpackages (check the Tags section in this repository):linux-imagetouch-keyboardyogabook-supportalsa-ucm-conf-yogabook
- Open a terminal emulator, navigate to the directory containing the
.debfiles, and install them using the commandsudo dpkg -i --force-depends *.deb. - Resolve any missing dependencies with the command
sudo apt -f install. - Reboot. Verify that the new kernel is in use with the command
uname -a(the output should include 'yogabook' in the version). - If the system has a newer kernel than the one you downloaded, reboot again,
select the Yoga Book kernel from the boot menu, and verify that it boots
successfully. After this, remove the default kernel from the system with
sudo apt remove linux-image-<version>command. - The touch keyboard should now be operational, allowing you to detach the OTG hub and enjoy your Yoga Book.
Known issues:
- Camera and vibration force-feedback don't work.
- alsa-lib (libasound2 package in Debian/Ubuntu) should has version >= 1.2.9
- To have automatic screen rotation working, it should be supported by desktop environment. Try Gnome first.
- My Yoga Book randomly freezes after some time. If you have the same behavior, let me know.
