Introduction
Even seasoned Linux users can run into unexpected roadblocks when the hardware is non‑standard. The ASUS Zenbook Duo, with its dual‑screen design and Intel Arc graphics, proved to be a perfect example of a laptop that looks great on paper but demands a lot of manual tweaking to run Linux smoothly.
Installation Hurdles
The first obstacle appeared before the installer even reached the graphical screen. Booting from the CachyOS ISO resulted in a black screen that lingered for minutes. The issue was traced to the Intel Arc GPU, which the default installer kernel does not handle well. Switching to the “safe mode” boot option allowed the installer to start, but it highlighted the need for custom kernel parameters on this device.
Device Compatibility Issues
After a successful installation, the core system functioned without major problems, yet several peripheral components behaved oddly:
- Intel Arc graphics required the
i915driver with specifici915.enable_psr=0andi915.force_probe=0x9a49parameters. - Secure Boot could be enabled post‑install without extra signing steps, which was a pleasant surprise compared to desktop experiences.
Touchpad & Keyboard Challenges
The Zenbook Duo splits its input devices into three separate entities: attached, detached (Bluetooth), and USB‑C. KDE Plasma recognized each as an independent device, forcing the user to configure them individually. This fragmented approach made simple tasks like adjusting sensitivity or enabling tap‑to‑click a time‑consuming process.
Function Keys & Second Display
Function keys did not map to their intended actions out of the box. The workaround was to bind them manually within the KDE System Settings, which is functional but far from the seamless experience Windows offers.
The secondary screen, a hallmark of the Duo, required manual positioning via the display settings. While the screen could be activated, the touch input never aligned correctly, and attempts to automate the activation (as MyASUS does on Windows) fell short.
Keyboard Backlight & Usability
Perhaps the most frustrating issue was the keyboard backlight. Without proper driver support, the backlight remained off, leaving the user in the dark during night‑time work. The problem persisted despite trying the asusctl package and community scripts.
Conclusion
Running Linux on the ASUS Zenbook Duo is possible, but it requires a willingness to troubleshoot driver quirks, manually configure input devices, and accept that some features (like automatic secondary‑screen activation and keyboard illumination) may never work perfectly. For users who need a laptop that works out‑of‑the‑box, a more Linux‑friendly device—or even a switch back to Windows or macOS—remains the safer choice.
