Do I need a swap partition on Lubuntu too? Or is it only recommended for Ubuntu? I was wondering why we need swap in the 1st place.

Lubuntu and Ubuntu are basically no different in the execution of the OS. They are differently when it comes to GUI and applications.

Swap space is the area on a hard disk which is part of the Virtual Memory of your machine, which is a combination of accessible physical memory (RAM) and the swap space. Swap space temporarily holds memory pages that are inactive. Swap space is used when your system decides that it needs physical memory for active processes and there is insufficient unused physical memory available.

You should use a Swap partition.

Here is a ref for you

Thanks a lot BlueXrider – Elysium Mar 25 '12 at 14:08
All Linux operating systems need swap space. As blueXrider states, the swap partition is virtual memory. – user97575 Oct 14 '12 at 12:20

simply NOT true. Especially Lubuntu is made for staying lean. If your machine doesn't load everything at boot time and you've got the typival 2GBs of ram, a swap is necessary like a fifth wheel on a car. Even Win XP Pro doesn't need a swap. I've got abaout 200 mb ram used on lubuntu saucy salamander and about the same for xp AFTER managing to disable all unwanted start-at-boottime-files, overdone Browser-cache, etc. It also keeps SSDs Lifetime longer, as there's (almost) no unnecessesary write procedures.

Only thing, which makes my laptops freeze is unwanted js-code from some websites.(sometimes, when I forget to turn js off in Browser-Options). But thats got nothing to do with swap or ram.
