StarBook Horizon

A refined 13.4-inch Linux laptop with open firmware, native Linux support, privacy hardware, and serviceable design. Choose the StarBook Horizon for everyday use, or the StarBook Horizon Plus for enhanced performance and refinements such as a larger battery and haptic trackpad.

Control it

How much of your current laptop do you actually control?

Most laptops let you change the operating system while the lower layers stay opaque. The StarBook Horizon is designed so the firmware, hardware security state, and service path remain inspectable below Linux.

Applications Choose your tools and workflow.

user level

Operating system Install Ubuntu, Fedora, Arch, Debian, openSUSE, NixOS, or another modern Linux distribution.

replaceable

Firmware Open-source coreboot with useful controls exposed to the owner.

inspectable

Hardware security BIOS Lock, TPM 2.0, measured boot support, Intel ME state, webcam cover, and Wi-Fi kill switch.

verifiable

Run the same security check locally.

Some distributions ship an older fwupdtool, so this check uses an upstream fwupd binary mirrored at a pinned commit. Verify the checksum, then read the result on your own screen. The output stays on your machine.

wget -O fwupdtool \

Change it

Firmware is part of the product.

The StarBook Horizon firmware is open source and model-specific. The controls below are examples from the firmware, giving you direct control over how the hardware behaves.

The StarBook Horizon internal fan and cooling assembly

Fan behaviour

Choose how aggressively the fan responds, from quiet operation for lighter workloads to more active cooling under sustained load.

Default: Normal
Options: Normal, Aggressive, Quiet, Disabled
Source: coreboot CFR

The StarBook Horizon firmware battery charging controls

Battery limits

Set the maximum charge level and charging speed in firmware to help preserve battery health when you don't need a full charge.

Default: 100%, 1.0C
Options: 100%, 80%, 60% charge limits
Use: Desk use, storage, battery care

The StarBook Horizon firmware flash chip

Security state

Control important security features directly in firmware, including BIOS Lock, Intel Management Engine state, Secure Boot and TPM-backed measured boot.

BIOS Lock: Enabled by default
Intel ME: Disabled by default
Detail: Firmware and security

More owner-facing firmware controls

The StarBook Horizon also gives you firmware-level control over Fn/Ctrl behaviour, keyboard backlight timeout, charge LED brightness, PCIe power management, S3/S0ix sleep modes, lid behaviour, webcam and microphone toggles, and VT-d.

What changes after saving?

These controls live in the firmware itself, rather than in a vendor application layered on top of Linux. Once saved, they apply independently of the operating system you run.

Install Linux

Install Linux. Any distribution.

The StarBook Horizon is built for standard Linux, not a single distribution. Install from normal installation media, use upstream drivers, and receive firmware updates through LVFS. The distributions below are examples, not an exhaustive list.

Supports Linux,
not a distribution. Standard ISO. Upstream drivers. No vendor-specific install required.

Ubuntu Kubuntu Fedora Fedora Silverblue Arch Linux Debian openSUSE openSUSE Leap NixOS Linux Mint LMDE Manjaro EndeavourOS Pop!_OS elementary OS Zorin OS MX Linux Gentoo Void Linux Alpine Tumbleweed Slackware Garuda Linux CachyOS Rocky Linux AlmaLinux Kali Linux Bazzite

Compatibility baseline

Clean baseline: Linux 6.2 or later.
The support target is the platform: modern Linux kernel, upstream drivers, and standard install media.
Firmware updates are delivered through LVFS on Linux.

What Linux support means

We support the Linux platform rather than certifying a fixed list of distributions. The StarBook Horizon uses standard installation media, upstream drivers and normal Linux update paths, without a proprietary recovery image or mandatory vendor software.

Verify it

Do not take our word for it.

The security story starts in plain English: protect the firmware, make the boot path measurable, keep Intel ME disabled, and expose reproducible checks instead of asking for trust.

Read the security detail

Plain-English protection

BIOS Lock protects firmware writes. Secure Boot and Measured Boot help verify the boot process where supported by your distribution, while dTPM 2.0 provides hardware-backed measurement and key storage.

Check it with fwupd

fwupd's Host Security ID check is a practical way to inspect platform security features from Linux. Distro builds can lag the upstream fwupd support needed here, so the StarBook page shows a checksum-pinned route to reproduce the check without inventing a score.

wget -O fwupdtool \

Source and methodology

Hardware

Built like the software matters.

Open firmware only matters if the hardware around it is worth keeping. The StarBook Horizon pairs a lightweight aluminium chassis with a high-resolution display, accessible internals, replaceable storage and battery, and physical privacy controls.
