MAUI, United States - DigitalToday reporter Dae-geon Seok (석대건) - Qualcomm is expanding supported operating systems for the Snapdragon X2 series to Linux. The aim is to let developers and partners building agentic AI use Snapdragon across a wider range of PC environments. Qualcomm said it will start supporting Debian by the end of this year, and set a target of certifying Ubuntu in the first half of 2027.

Qualcomm unveiled an Early Developer Preview for Linux for the Snapdragon X2 series at Snapdragon Summit 2026 in Maui, Hawaii, on Sept. 23 local time. Linux is the third operating system supported by the X2 series, after Windows and Chromebook.

With the expansion, more developers and partners will have a foundation to build Snapdragon-based agentic AI across a wider range of PC environments. Qualcomm said Linux support had been one of the most requested features. Qualcomm said it had stayed at the kernel level, but will now support the X2 series directly as a single platform. For developers to use the X2 series' AI performance on Linux, drivers that handle the platform's compute devices must first be included in the kernel.

Qualcomm is first pushing to integrate Hexagon NPU and Adreno GPU drivers into the Linux kernel. The Hexagon NPU is used for on-device AI inference through the fastRPC driver. The Adreno GPU handles graphics and compute through open-source Mesa drivers Freedreno, Turnip and Rusticl.

Those drivers will be integrated through an upstream approach. Upstreaming puts drivers into the official Linux kernel so distribution maintainers can follow kernel updates without separate patches. Out-of-tree patches can help with early bring-up, but Qualcomm said mainline support is what developers can rely on across multiple kernel versions. The upstream targets also include support for key peripherals, DSP and multimedia hardware blocks in addition to the NPU and GPU.

The current Early Developer Preview support scope is limited to laptops with the X2 series. It does not include desktop form factors, the previous Snapdragon X platform or other development boards. Readiness also varies depending on manufacturer designs and X2 series products. Work so far has been validated on a Debian 13 ("Trixie")-based user environment and a custom kernel. The preview is also aimed at distribution maintainers, kernel contributors and hardware support engineers. An environment that general users can install and use right away is expected after distributions provide feedback on upstream results.

The support scope will expand in stages. In the initial phase, the focus is on booting, core input and output such as USB and PCIe, graphics and display, AI acceleration through the NPU, and power and thermal management. In the expansion phase, it will increase supported peripherals and the patches reflected in the kernel to improve stability to a level that can support development of real workloads.

The first supported distributions are Debian and Ubuntu. Debian, which underpins many Linux distributions, will start receiving support by the end of this year. Ubuntu is targeting X2 series certification in the first half of 2027 in cooperation with developer Canonical. Among device makers, HP, Asus and Humain plan Linux support in 2027.

Humain unveiled at the summit an AI PC called the "Horizon Ultra" that uses the X2 Elite and runs both Linux- and Windows-based software. Qualcomm plans to continue upstream work after November 2026 to support kernel updates, certification and manufacturers' commercialization.
