Surface Book 3

Using the Built-In Keyboard with Disk Encryption

You need to ensure that the following modules are included in the initramfs/initrd (e.g. by editing mkinitcpio.conf):

• surface_aggregator, surface_aggregator_registry, surface_aggregator_hub, surface_hid_core, and surface_hid
• intel_lpss and intel_lpss_pci
• 8250_dw (required for communication with the embedded controller)

Rebooting gets stuck at the Surface logo

Add reboot=pci to your kernel boot parameters.
