Page to keep track of Linux support development for Thinkpad X13s (SoC codename sc8280xp), the first Thinkpad with an Arm CPU.
Most of the following information comes from #aarch64-laptops on OFTC, #fedora-arm on Libera.chat and arm[AT]lists.fedoraproject.org. Upstream information changes daily, so this page may be outdated.
Bootable images
Fedora 41 GA works relatively well OOTB. The Workstation raw image can be used with the following additions:
- The kernel must be booted with the kernel parameters
arm64.nopauth clk_ignore_unused pd_ignore_unused - A recent firmware must be on the machine:
- Minimum: Version: N3HET84W (1.56)
- Latest: Version: N3HET91W (1.63)
- Instructions for how to update the firmware without Windows are on this GitHub repository.
- There are two ways to load the correct device tree:
- Enable the Linux Support boot option in the firmware boot menus, and copy the
/boot/dtb/qcom/sc8280xp-lenovo-thinkpad-x13s.dtbfile to the root of the ESP partition.- Debian has instructions on how to do this from windows
- After major kernel updates, you should run
sudo cp /boot/dtb-`uname -r`/qcom/sc8280xp-lenovo-thinkpad-x13s.dtb /boot/efi
- Alternatively you can tell grub about the correct DTB so that you don't have to manually copy the DTB to the ESP. This approach will let you install newer kernels via
dnf.- Add a the following line to the /boot/loader/entries/* file(s):
devicetree /dtb/qcom/sc8280xp-lenovo-thinkpad-x13s.dtb
- Edit
/etc/default/grub, and add the kernel parameters listed above toGRUB_CMDLINE_LINUX. Add a new line: `GRUB_DEFAULT_DTB=/dtb/qcom/sc8280xp-lenovo-thinkpad-x13s.dtb
- Edit
/etc/kernel/cmdline, and add the kernel parameters listed above.
- Add a the following line to the /boot/loader/entries/* file(s):
- Enable the Linux Support boot option in the firmware boot menus, and copy the
- Once the system is running, installing the x13s copr, will pull in the remaining dependencies and correct a few configuration items:
sudo dnf copr enable jlinton/x13s; dnf install x13s sudo reboot
Known Problems
- TPM support is missing
- 5G Modem
- Need to follow the documented steps to unlock the modem
- Virtualization is not available. The UEFI is not yet exposing the EL2 (exception level), which is required to run VMs
- There has been some work done to unlock it with https://github.com/TravMurav/slbounce. YMMV
- The system does not suspend correctly so you need to poweroff if leaving unused
- Camera is not working. There are patches going upstream. You need to add
cma=128M - Bluetooth doesn't always work
