Swap, nowadays, is good for hibernation, and that's it (as far as I am concerned, anyway), which is why I have the same size swap as my available RAM.
Of course, I am running a traditional SATA drive, so I am not worried about abusing an SSD.
Moody, do you have rotating cube in that Kubuntu? It is running Plasma?
I'm thinking maybe I could build a virtual machine and tweak KDE at my leisure before going for a full install.
