[Data] Surface Pro 11 (Intel Core Ultra 7 266V, Business Model) - Partial support, missing audio events
Device Information: • Model: Surface Pro 11 for Business (Intel) • CPU: Intel Core Ultra 7 266V (Lunar Lake) • BIOS Version: 13.10.143 (2025-03-25) • OS: NixOS 25.05 (Kernel 6.12.x mainline) • Accessories: No original Type Cover keyboard or Surface Pen purchased; a wired USB keyboard works normally.
⸻
Summary:
NixOS 25.05 runs mostly fine on the Surface Pro 11 (Lunar Lake), but several hardware components are not yet supported out of the box.
Working: • Touchscreen • Wi-Fi • Bluetooth • Bluetooth audio output • Wired USB keyboard (works as expected) • Battery status detected
Not working / missing features: • Internal speakers produce no sound • Built-in microphones not functional • Short press of the power button does nothing (no suspend event) • Camera not detected（hardware same as SP10）
⸻
Attached Files: I’ve included the following data files for further analysis: • dsdt.dat • dmidecode.txt • dmesg.txt
All three are collected from the NixOS installation environment.
If any additional logs or tests (ACPI, EC, audio codec dump, etc.) are useful, I’m happy to provide them.
I am not sure how easy it will be to get cameras working, but I guess the first step is to figure out the sensors. While you are booted into windows you can check which camera sensors it has: what it looks like for sp10: https://github.com/linux-surface/linux-surface/discussions/1354#discussioncomment-13540801

Thanks！I checked the hardware, and the Surface Pro 11 (Intel) uses the same camera sensors as the Surface Pro 10 (IMX681 + OV13858 + VD55G0).both still rely on the IPU6 pipeline, which is not supported yet.So it seems the SP11 cameras will also not work on Linux at this point.
