# "Boot into: gamescope / desktop" menu item, on top of the SteamOS
# conversion. Gamescope is the default (the conversion's autologin, and
# CachyOS's cachyos-gamescope-autologin resetting to it after a desktop
# session). Desktop: a unit that sets the autologin session to Plasma at
# every boot, before the login manager starts. Switching between the two in
# a running system (Return to Gaming Mode, Steam's Switch to Desktop) works
# the same either way.
# Sourced by steamify.sh; not meant to be run on its own.
