# Once upon a time we were encouraged to go against long-standing UNIX

# But since to change this we'll have to dig through the system and make

# It's more than likely on the TODO list to change these back to
# 65534:65534, however.
# Meanwhile we'll at least change this from a sed to a patch.
# Always hated sed in these situations because the underlying code can change

# OK, here's the scoop on s2idle. After doing some digging, it looks like both
# Intel and AMD have stopped officially supporting S3 sleep (aka "deep") with
# the latest generation of CPUs (although it "might work"). I've also seen a
# few people say that S3 is "not secure"... which if you're worried that a
# three letter agency might grab your sleeping laptop and extract the contents
# of the RAM while keeping it powered up, well, maybe in that sense it isn't.
# As far as s2idle, I have heard that it has the potential to be as much of a
# low power mode as deep, but that depends on how low the IRQ rate gets. In
# practice I have heard of s2idle draining a battery in half a day.
#
# Anyway, I tried s2deep here again (with the below sleep patches) and it still
# locks up my machine (a fairly recent Thinkpad X1).
#
# S3 works and has the best power savings of all the partially-on modes.
# Feel free to edit /etc/elogind/sleep.conf.d/10-elogind.conf if s2deep works
# for you, but we'll continue to default to deep for now.
#
# Don't prefer s2idle, as it doesn't seem to work:
