Installation

After kernel 5.4, automatic GuC / HuC firmware loading will cause issues with the i915 driver. The attached DSI display will work correctly, but HDMI and DisplayPort may show a blank screen on plug or cause hangs on resume from hibernate. On modern kernels, there is no resolution for DP support over the USB-C connection. Rebooting while the USB-C port is attached to a DP screen will allow it to function for that session only, hibernation will cause a hang at a blank screen. For mostly functional HDMI support, it is necessary to pass the following kernel parameters to configure i915: 

i915.modesset=-1 i915.enable_guc=0 i915.enable_dpcd_backlight=0 i915.disable_power_well=1 i915.enable_fbc=0 i915.reset=1 i915.mitigations=auto i915.fastboot=0

Configuration

kernel modules

For an working keyboard during boot, add battery to the preloaded modules: 

/etc/mkinitcpio.conf
...
MODULES=(battery)
...

screen rotation during boot

For correct screen rotation during boot, add fbcon=rotate:1 to your bootloader config: 

/boot/loader/entries/arch.conf
...
options root=/dev/mapper/crypt cryptdevice=UUID=000ccc23-4223-0ccc-4223-deadbeaf2342:btrfs rw fbcon=rotate:1
...

wayland

The screen is on DSI-1 and 90° rotated, so you need to configure this: 

~/.config/sway/config
...
# configure display
# get the names of your outputs by: swaymsg -t get_outputs
output DSI-1 resolution 720x1280 transform 90
...
