Of course I meant /sys/power/state, not /sys/state/power...

Also: Using <sudo ...>, the screen blackout (and subsequent logging of
"Failed to open /sys/power/state: Permission denied" in tty1
no longer show up after using gnome-tweak-tool to set "Don't suspend on lid
close" to "ON" in "Power > When Laptop Lid is Closed".

NB, this does not solve the 30-second suspend thing; I still need to do a
chmod 444 on every boot to make sure I can use my laptop for more than 30
seconds at a time.
