Installation

Installing Arch was mostly without hiccup, you do need to disable Secure Boot ( for UEFI options; for boot options). Dual boot was not tested. The laptop does not have a CD drive, so you have to use a USB stick. The UEFI also would not startup from the USB stick, but you can browse the USB, and choose the loader.efi to startup from.

Audio

Only the front speakers work out of the box.

Accelerometer

The accelerometer is not found by any userspace programs, gives the following output:

The accelerometer is connected to a new Intel Integrated Sensor Hub which is not supported by the kernel yet, but can be manually bound to the driver:

$ lspci -nn | grep 8086:a135
