Lenovo Legion Tab Gen 5 · Legion Y700 5th Gen · TB323FU
Mainline Linux on the TB323FU
A port of the mainline Linux kernel to Lenovo's gaming tablet with the Snapdragon 8 Elite Gen 5 (SM8850 “kaanapali”, board “baldur”). The kernel port is the core: a patch series, the board device tree and the config. Distributions and desktop integration are optional add-ons.

Hardware status
Full table →A feature counts as working only when it was measured or seen on the device — a probing driver does not count. Last updated 2026-10-04.
- works
- partial
- does not work
- not verified
- n/a or not implemented
Distributions
Details →The kernel does not depend on a distribution. These have been built with the scripts in rootfs/ and booted on the tablet, each from its own partition.
- Debian 13 (trixie)
- Ubuntu 26.04 LTS
- Arch Linux ARM
- Fedora 44 Workstation + FEX
- NixOS 26.11 (unstable)
- SteamOS (arm64, community handheld port)
- Armada 20260926 (Fedora bootc, experimental)
Open Device Helper
Details →The tablet's own settings, in a GNOME quick-settings tile, a settings app and a command line (tb323fu-ctl), over one D-Bus service:
- Charge limit, bypass charging and a “full by” schedule; battery health and the charger's power
- Refresh policy and panel heat protection
- Performance profiles with CPU and GPU limits, CPU boost and thermal profiles
- Torch, LED ring colors and effects, vibration strength
- USB-C port roles and wake sources, the emergency key
- Restart into Android, choose the system to boot
- Kernel updates from this project's releases, tried on the next start and rolled back if it fails
