The computer suspends to RAM and computer enters low-power state where RAM is
kept warm and the lid-open interrupts is monitored, but little else. (actually
KDE3 at the moment).

The only non-default entry in my login.conf is the power-button, because I
like being able to press the power-button and leave the lit open and still
suspend to RAM, e.g.

$ noc /etc/systemd/logind.conf
[Login]
HandlePowerKey=suspend


The 'hibernate' writes to disk and then enters a poweroff state but leaves the
filesystems with a flag set to show they are still in use. I have never liked
hibernate on dual-boot systems just for that reason.
