Since I'm installing Ubuntu for the first time ever (please don't shoot) i have no idea how large the swap partition should be. On the one hand, I know that people recommend "double the ram unless it makes swap larger than 2GB", but I also know that to hibernate I need swap=ram... I have 4GB of ram. Should I make my swap partition 4GB also, to be able to hibernate later?
Note: the last time I contemplated installing Ubuntu was when 12.04.4 was new-ish, so my information might be out of date.
