Settings

Video

For Intel GMA HD (Bay Trail) acceleration install: xf86-video-intel.

For Vulkan support, you can install vulkan-intel, but rendering of polygons on Bay Trail/Ivy Bridge is extremely buggy as of June 2017.

LAN

Works out of the box, via r8169 kernel driver. You may wish to remove the module if working on battery power and not using Ethernet, as the hardware consumes about 719mW even when not connected. This might be a NetworkManager issue -- testing needed.

Wi-fi

Works out of the box, via ath9k kernel driver.

Audio

Works out of the box.

Touchpad

Works out of the box.

Brightness

fn + F5 / fn + F6 - control brightness.

Webcam

Works out of the box, via uvcvideo driver in kernel.

Card Reader

Works out of the box.

Dual boot with Windows

Note: This part is copied straight from the ASUS X551MA article. I have never attempted to run Windows in dual-boot setup on this laptop.

To boot Windows 7 it is needed to switch on CSM at BIOS. Otherwise Windows boot hangs at logo. Set the BIOS setting OS Selection in the Advanced menu to Windows 7.

Slowdown on 4.x kernels

Using pstate CPU frequency governor sometimes causes the frequency to become locked to the lowest possible frequency, 500MHz. This seems to happen when the charger is unplugged. Add intel_pstate=disable to the kernel line in grub to avoid this, at the slight disadvantage of being locked out of the "boost" frequencies -- this comes down to having a max of 2.16GHz instead of 2.42GHz -- and possibly slightly worse power consumption.
