Notes

Installation

You have to disable Secure Boot. repeatedly press F10 during boot to bring up the BIOS setup, navigate to the boot section and disable Secure Boot.

To prevent the system from booting in Legacy mode, it is also recommended to disable CSM/Legacy mode.

WiFi

For WiFi driver install broadcom-wl-dkms package, or broadcom-wl if you use stock non lts kernel.

Bluetooth

For Bluetooth driver install bcm43142a0-firmwareAUR package.

Tablet mode

Keyboard disables and enables out of the box. However, for touchpad it is necessary to create udev rule: 

/etc/udev/hwdb.d/90-custom-keys.hwdb
evdev:atkbd:dmi:*
  KEYBOARD_KEY_d7=!f22
  KEYBOARD_KEY_d8=!f23

KDE Plasma

In KDE Plasma 5 it works out of the box.

Sway

Create ~/.config/sway/config.d/tablet_mode.conf file 

~/.config/sway/config.d/tablet_mode.conf
# Tablet mode
bindcode 200 input type:touchpad events enabled
bindcode 201 input type:touchpad events disabled

In addition, squeekboardAUR (with sway-gitAUR and wlroots-gitAUR) supports auto show/hide feature, and to enable it when using tablet mode, change the config to 

~/.config/sway/config.d/tablet_mode.conf
# Tablet mode
bindcode 200 input type:touchpad events enabled, exec 'killall squeekboard'
bindcode 201 input type:touchpad events disabled, exec 'squeekboard &'

Other Desktop Enviroments

Other DEs are either untested or does not support this feature.

Kernel parameters

For tablet mode to work correctly, add 

acpi_osi=!

and 

acpi_backlight=vendor

for better backlight manipulation.
