These are manual instructions on enabling SSH access on your Steam Deck, adding public key authentication, and removing the need for a sudo password for the main user (deck).

This gist assumes the following:

you have a Steam Deck
you have a home PC with access to a Linux shell that can ssh, ssh-keygen, and ssh-copy-id
your Steam Deck and home PC are on the same local network, with standard SSH traffic (tcp/22) allowed over that network from the PC to the Steam Deck

NOTE: @crackelf on reddit mentions that steamOS updates blow away everything other than /home, which may have the following effects:

removing the systemd config for sshd.service, which would prevent the service from automatically starting on boot
removing the sudoers.d config, which would reenable passwords for sudo

	# The peripheral clock is 80MHz or 12.5 nanoseconds per clock.
	# The smallest precision of timing requried for neopixels is
	# 0.35us, but I've decided to go with 0.05 microseconds or
	# 50 nanoseconds. 50 nanoseconds = 12.5 * 4 clocks.
	# By dividing the 80MHz clock by 4 we get a clock every 50 nanoseconds.
