I had a good hunch you wouldn't be satisfied with Gnome :)

That's cool! Do you think this would fit somewhere in the Wiki or as an 
AUR package? Are you sure you want hybrid-sleep instead of plain

run the risk of running your battery all the way down, which supposedly 
isn't healthy for the battery
