Gentoo Linux on the Lenovo Thinkpad X1 Tablet Third Gen (X1Y3 / 20KJ / 20KK)
The following write up covers my trials and tribulations getting everything working properly on this device. While my instructions are Gentoo specific, this should be useful no matter what distro you’re running. If you are NOT using Gentoo, just keep in mind when I enable “USE flags” for packages in Gentoo, this automatically pulls in any dependencies necessary to enable those features. In your distro, it may be necessary to install additional packages not listed. For example: To install Apache with mod_php in Gentoo you can simply enable the “apache2” USE flag in dev-lang/php. In Fedora or Debian … you’ll need to install a separate package for mod_php (typically something like httpd-php7 or similar). Also bear in mind I’m using KDE Plasma for my DE, so you’ll need to swap out with equivalent things in your DE of choice when it comes to that. With that caveat out of the way … let’s get to hardware info and setup.

Kernel Config
Quite a few things you’ll need aren’t enabled by default by genkernel, so you’ll want to go over this list carefully if you are using Gentoo. If you’re using a binary distro you’ll still not want to entirely skip this over, as I did have to patch my kernel to get support for the trackpoint. Speaking of, here’s a link to the patch which is in the Linux kernel, but less than 30 days old as of the time of this writing. This means unless you’re rocking kernel 5.0.2 or so or newer (or have backports that recent) … you’ll need to manually patch your kernel too for trackpoint support. You’ll want the following options enabled:CONFIG_NVME_CORE=m CONFIG_BLK_DEV_NVME=m CONFIG_THINKPAD_ACPI=m CONFIG_THINKPAD_ACPI_ALSA_SUPPORT=y CONFIG_THINKPAD_ACPI_VIDEO=y CONFIG_THINKPAD_ACPI_HOTKEY_POLL=y CONFIG_IWLWIFI=m CONFIG_IWLWIFI_LEDS=y CONFIG_TOUCHSCREEN_WACOM_W8001=m CONFIG_TOUCHSCREEN_WACOM_I2C=m CONFIG_HID_WACOM=m CONFIG_HID_MULTITOUCH=m CONFIG_HID_GENERIC=y CONFIG_INPUT=y CONFIG_INPUT_LEDS=y CONFIG_INPUT_EVDEV=y CONFIG_INPUT_KEYBOARD=y CONFIG_INPUT_MOUSE=y CONFIG_INPUT_TABLET=y CONFIG_INPUT_TOUCHSCREEN=y CONFIG_INPUT_MISC=y CONFIG_USB_VIDEO_CLASS=m CONFIG_BT=m CONFIG_BT_HIDP=m CONFIG_BT_HS=y CONFIG_BT_LE=y CONFIG_BT_INTEL=m CONFIG_BT_HCIBTUSB=m CONFIG_SND_HDA=m CONFIG_SND_HDA_INTEL=m CONFIG_SND_HDA_PREALLOC_SIZE=2048 # Because of PulseAudio CONFIG_MICROCODE=y CONFIG_MICROCODE_INTEL=y

Setup Dual Boot Quickly
The following is how I setup things so that I could install Linux setup for dual boot while Windows 10 installed a billion updates. I keep Windows 10 around mostly to test websites in IE/Edge, but it is also an easy way to update the BIOS and firmware through the Lenovo software update thing.
1) Install VirtualBox including the Extension Pack for Windows.
2) Download SystemRescueCD 5.3.2 (the last version they released based on Gentoo, but still quite current) and set it up in VirtualBox as a boot CDROM.
3) Use Windows Disk Manager (search “Disk Manager” in the start menu) to resize Windows and create new partitions. DO NOT have Windows format the partitions for you. Having Windows resize itself is necessary because Lenovo ships Windows by default BitLocker encrypted. Windows can shrink itself on a running drive and create new partitions on said drive. I personally setup a root partition, LUKS encrypted home partition, and swap partition (for hibernation purposes, and because you’d be surprised how much memory webkit or chromium take when compiling).
4) Use the following trick to be able to mount real partitions as drives in VirtualBox. Note this requires launching VirtualBox and the Windows CMD prompt as Administrator.
5) Go ahead and update Windows and use the Lenovo portal to update system firmware, BIOS, drivers, etc. Note that if you have to reboot at any time you can simply have VirtualBox freeze the VM and you can then pick up your Linux install where you left off after rebooting.
6) Complete installation of Linux using your distro’s instructions, but keeping in mind the specific hardware and settings mentioned above.
Post Install Tweaks
BIOS Changes
You’ll definitely want BIOS assist mode on for Thunderbolt. I also in general turn off all the Intel ME/TPM stuff that I possibly can. If Lenovo has shipped an updated BIOS by the time you read this (see below), be sure to enable “Linux” mode for sleep in the BIOS.
Important USE Flags
# cat /etc/portage/package.use/* net-wireless/bluez btpclient extra-tools deprecated sys-apps/fwupd nvme thunderbolt uefi >=sys-boot/grub-2.02-r1 mount sys-firmware/intel-microcode initramfs app-portage/layman subversion media-sound/pulseaudio native-headset ofono-headset
Intel Microcode
This will help patch some (but not all) CPU vulnerabilities as well as improve any issues stemming from errata relating to bugs in CPU design. Edit/Add the following line to /etc/default/grub to load the Microcode at boot: GRUB_EARLY_INITRD_LINUX_CUSTOM=”intel-ucode.cpio” Run the following commands, noting that the first is to install if you’re not using Gentoo:
# emerge -va --quiet sys-firmware/intel-microcode # iucode_tool -S --write-earlyfw=/boot/intel-ucode.cpio /lib/firmware/intel-ucode/* # grub-mkconfig -o /boot/grub/grub.cfg (Or whatever the command is to regenerate the GRUB2 config on your distro)
Custom DSDT Tables for S3 Sleep
As of the time of this writing, Lenovo has not shipped a BIOS for this machine with proper S3 listings for deep sleep in the BIOS. This is because this newer Intel system supports a software deep suspend that gives the OS greater granular control over what goes to sleep and how deeply it goes to sleep. This is sadly a highly Windows-centric and specific feature and was pushed by Microsoft as their preferred way to do things. Lenovo has shipped updated BIOS images for similar Thinkpad hardware giving a new BIOS option for proper S3 sleep in Linux. If you don’t patch the DSDT tables, you’ll get maybe a half day to a day on sleep. If you have proper S3 sleep it’s more like a week of sleep time. Read here (be sure to scroll down!) for the somewhat involved details for creating your own DSDT tables and patching them over your BIOS ACPI tables at boot time. Note this means you’ll be modifying the GRUB2 line you’ve already touched above to deal with Microcode. And since you just modified GRUB2 let’s go ahead and cover all the changes we’re going to make in GRUB2:
GRUB2 Tweaks
Note that by adding the “mount” USE flag to GRUB2 above, if you now install os-prober Gentoo will automatically search for Windows installs and add them to your GRUB2 config. In addition I’ve changed the following settings in my /etc/default/grub:
GRUB_FONT=/boot/grub/terminus.pf2 # High DPI monospace console font GRUB_GFXMODE=3000x2000 # Native Resolution GRUB_CMDLINE_LINUX_DEFAULT="quiet mem_sleep_default=deep resume=/dev/nvme0n1p4" # Sleep line default behavior after kernel 4.18, resume should point to your swap partition (or file) GRUB_EARLY_INITRD_LINUX_CUSTOM="intel-ucode.cpio acpi_override" GRUB_GFXPAYLOAD_LINUX=keep GRUB_BACKGROUND="/boot/grub/aurora.png" # Use any 3000x2000 png you want
KDE Plasma High DPI
KDE System Settings has everything you’ll need to tweak things for High DPI. Of particular note is the force font DPI scaling setting under fonts. The taskbar scales well, though some GTK apps like connman do look like you’re zooming in at 500% on a tiny icon.
Putting Your Powertop/S3 Changes To The Test
If you have chosen to install fwts, unplug your laptop on full battery and then run:
# fwts --power-states
It will now conduct a test of S3 and S4 and report back errors and estimated battery life duing sleep.
Unexplored/Unsupported
I’m not interested in tablet auto-rotation (I get annoyed by it flipping too much while I’m walking) so I have a tray widget that lets me use KDE’s control panel to adjust the orientation on demand any time I want. It’s possible to do auto-rotation from my understanding (if your desktop environment supports that sort of thing) if you’re so inclined. I’m simply not inclined.
The fingerprint reader is totally unsupported though efforts have been made to reverse engineer it.
lm-sensors does not seem to have the necessary recognition of the onboard hardware monitoring. This feels like it has been the standard operating procedure for as long as I can remember with lm-sensors … if you buy something new, don’t expect lm-sensors support off the bat. It took a year or two with all my desktop builds before support for their HW sensors trickled down into kernels I was running. Coretemp and ACPI temperature readouts work just fine, but it sees a proper sensor it just can’t use. Output from sensors-detect and then sensors:
# sensors-detect (snipped output) Some Super I/O chips contain embedded sensors. We have to write to standard I/O ports to probe them. This is usually safe. Do you want to scan for Super I/O sensors?
