Touchpad

Works after installing xf86-input-libinput.

UX305CA users will require linux 4.5 or later in order for touchpad to work.

Palm detection

If default Palm Detection doesn't work well, one can manually disable part of the trackpad by setting AreaEdge properties.

You can do this on the fly or add these parameters in the config file:

$ /usr/bin/synclient AreaLeftEdge=500 AreaRightEdge=2500

Middle click

Three finger tap should work with libinput.

If you are still using the xf86-input-synaptics driver, you can enable three finger tapping by running:

$ /usr/bin/synclient TapButton1=1 TapButton2=3 TapButton3=2

Wifi

Intel Dual Band wifi. Should work with recent kernels. 3.10+ with iwlwifi. See Wireless network configuration#iwlwifi for details.

Graphics

As of linux 4.0 with corresponding Intel drivers, no additional configuration is required to get X server to work.

UEFI results with memory changes for the Intel graphic card:

 With 32-256MB memory assignment in bios: Works.
 With 512MB memory assignment: X11 breaks. 1/3th upper-part of screen semi works (swapped and mis-alligned), rest is noise/snow.

Bug: https://bugzilla.redhat.com/show_bug.cgi?id=1151757

QHD+ Pentile Display

Some models include a 3200x1800 (faux-3200x1800 RG/BW Pentile) screen, which displays very tiny characters, and can make them difficult to read due to its incomplete subpixel matrix.

For Firefox and Thunderbird, add the below property in the about:config area

 layout.css.devPixelsPerPx=2.

Function Keys

As of linux 4.10, pressing Fn+F5 (brightness down) and Fn+F6 (brightness up) works without additional configuration on the UX305CA. Fn+F7 (blank display) still doesn't work.

Kernel 3.16 with acpi_listen, when pressing Fn+F12 (volup), Fn+F11 (voldown), Fn+F10 (mute), F9 (disable mousepad):

 button/volumeup VOLUP 00000080 00000000 K
 button/volumedown VOLDN 00000080 00000000 K
 button/mute MUTE 00000080 00000000 K
 PNP0C14:00 000000ff 00000000

The ambient light sensor button (fn+a) returns:

 PNP0C14:00 000000ff 00000000

Tested with:

# modprobe -D asus-laptop

And/Or:

# modprobe -D asus-nb-wmi

No effect so far. Investigate.
