[MajsknuaaEXE]

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:

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.
