System Configuration


The current driver for RTL8723BE PCIe Wireless Network Adapter can drop signals due to a power saving bug. This can be fixed with a quick command.

# iwconfig wlp3s0 rate 54M

Hybrid Graphics

Out of the box, the integrated card is used while the radeon driver dynamically powers off the discrete card. For use of discrete card, see PRIME.


The clickpad that is used is from Alps. Specifically, it uses Alps protocol 8 which has initial support in kernel 4.1. While basic functionality works with kernels less than 4.1, there may be issues that occur with use in kernel less than 4.1.

For more advance features such as Vertical Edge Scrolling, see Touchpad Synaptics. An interesting quirk that occurs is that in order to be able to use Vertical, or Horizontal, Edge Scrolling you have to enable Two Finger Scrolling. Setting only the Edge Scrolling option in xorg does not enable it.

Suspend to ram

Works out of the box.


Fn and Ctrl keys can be swapped in BIOS.

Fn key lock can be switched with Fn + Esc.

Known issues


Issue (kernel < 4.1):

After a certain amount of time used, the clickpad interrupts cease to be processed.

Work-Around (Non-Permanent):

Reload the "psmouse" kernel module when functionality ceases. Eventually it will cease up again requiring another reload.

# modprobe -r psmouse
# modprobe psmouse


The audio will not work with Alsamixer alone, but it will with puleaudio-alsa.
