The Omarchy Linux distribution, built on Arch Linux and long confined to x86_64 machines, has published its first AArch64 build with the release of Omarchy 4.5-RC1 — and according to Phoronix's report on the release, the new version delivers initial AArch64 support focused on Snapdragon X and NVIDIA N1X laptops, marking the first time the distribution has targeted ARM hardware at all.
That makes 4.5-RC1 a notable milestone for anyone tracking the practicality of running Linux on modern ARM notebooks. Omarchy has, until now, been effectively an x86-only project; a release candidate that opens the door to ARM suggests the maintainers see enough maturity in that hardware ecosystem to commit engineering effort to it.
Why ARM Linux laptops matter now
For developers weighing a move to ARM-based hardware, the practical takeaway is that the Linux laptop shortlist is no longer effectively an x86-only conversation. Devices in the Snapdragon X family — Qualcomm's ARM-based laptop platform — and NVIDIA's N1X entry into ARM computing are precisely the class of machines where users have historically had to choose between the vendor's operating system and a Linux install that might only half-work.
The N1X, for context, is NVIDIA's ARM-based computing platform aimed at laptops, part of the broader industry shift toward ARM silicon in the notebook segment. Organisations and individuals specifying new developer hardware are among those this affects: until distributions like Omarchy begin shipping working builds, prospective buyers of such hardware have had limited options among curated, opinionated Linux distributions.
Caveats: this is a release candidate, and "initial" means initial
The RC in 4.5-RC1 matters. This is a release candidate, not a stable release, and Phoronix describes the ARM support as initial rather than complete. Readers should expect rough edges — hardware enablement for ARM laptops is an area where driver coverage for GPUs, suspend and resume behaviour, audio, webcam, and peripheral support often arrive incrementally rather than all at once.
Omarchy is also a community-scale project rather than a large commercial distribution. That matters for expectations: bug reports filed against the new AArch64 builds will be triaged by a comparatively small team, so ARM-specific fixes may take longer to land than users of larger distributions are accustomed to. Treating early, detailed bug reports as part of the testing process — rather than as evidence the effort is failing — is the right posture for anyone trying the RC on real hardware.
Anyone running Omarchy in a production capacity should stay on the current stable branch until 4.5 is finalised.
The bigger picture
The story here is less about a version number than about trajectory. A distribution that has spent its existence centred on x86_64 is now building for ARM precisely as that hardware class matures, which is a signal worth reading alongside the continued growth of ARM silicon in laptops from both Qualcomm and NVIDIA.
Developers running x86_64 Omarchy today can expect the 4.5 cycle to be a normal upgrade path; those with ARM hardware in hand or on order now have an RC to test against. Either way, the release indicates that the curated-Linux-on-ARM-laptop space is getting more competitive, and that buyers no longer need to treat ARM as a Linux dead end.
Omarchy 4.5-RC1 is available now; the full release notes and download images are listed in Phoronix's coverage of the release.
以 Arch Linux 為基礎、一直僅限 x86_64 機器的 Omarchy Linux 發行版，隨著 Omarchy 4.5-RC1 的發布，首次推出 AArch64 版本——根據 Phoronix 對該版本的報道，新版本提供初步的 AArch64 支援，集中於 Snapdragon X 及 NVIDIA N1X 筆記簿，這是該發行版首次針對 ARM 硬件。
這使 4.5-RC1 成為任何關注在現代 ARM 筆記簿上運行 Linux 可行性的人士的重要里程碑。Omarchy 至今實際上只是一個 x86 專屬項目；一個為 ARM 打開大門的 release candidate，顯示維護者認為該硬件生態系統已足夠成熟，值得投入工程資源。
為何 ARM Linux 筆記簿現時重要
對考慮轉用 ARM 架構硬件的開發者而言，實際的啟示是 Linux 筆記簿的候選名單已不再是 x86 專屬的討論。Snapdragon X 系列——Qualcomm 的 ARM 筆記簿平台——以及 NVIDIA 進軍 ARM 計算的 N1X，正是用戶以往必須在廠商操作系統與可能只有一半功能的 Linux 安裝之間作出選擇的機器類別。
作為背景，N1X 是 NVIDIA 面向筆記簿的 ARM 計算平台，屬行業整體轉向筆記簿領域 ARM 晶片的一部分。正在為新項目選購開發硬件的機構與個人，正是受此影響的群體之一：在 Omarchy 等發行版推出可用版本之前，此類硬件的潛在買家在精選、有明確主張的 Linux 發行版中選擇有限。
注意事項：這是 release candidate，而「初步」就是初步
4.5-RC1 中的 RC 至關重要。這是 release candidate，並非穩定版本，而 Phoronix 將 ARM 支援描述為初步而非完整。讀者應預期會有粗糙之處——ARM 筆記簿的硬件啟用方面，GPU 驅動覆蓋、掛起與恢復行為、音訊、視像鏡頭及周邊設備支援，往往需要逐步到位，而非一蹴而就。
Omarchy 亦只是社區規模的項目，而非大型商業發行版。這對期望值有影響：針對新 AArch64 版本提交的 bug 報告，將由一個相對較小的團隊分類處理，因此 ARM 特定的修復可能需要較長時間才會落地，較大型發行版的用戶未必習慣。將早期提交的詳細 bug 報告視為測試過程的一部分——而非視為項目失敗的證據——是任何在真實硬件上試用 RC 的人士應有的正確態度。
任何以生產用途運行 Omarchy 的用戶，應繼續留在目前的穩定分支，直至 4.5 正式定稿。
更宏觀的圖景
此處的重點與其說是版本號，不如說是發展軌跡。一個一直以 x86_64 為核心的發行版，恰在此類硬件成熟之際開始為 ARM 構建，這是一個值得與 Qualcomm 及 NVIDIA 在筆記簿領域 ARM 晶片持續增長一併解讀的訊號。
目前運行 x86_64 版 Omarchy 的開發者，可預期 4.5 週期會是正常的升級路徑；而已持有或已訂購 ARM 硬件的人士，現在有一個 RC 可供測試。無論如何，此次發布顯示 ARM 筆記簿上的精選 Linux 領域正變得更具競爭力，買家亦不再需要將 ARM 視為 Linux 的死胡同。
