I installed ubuntu 14.04.1 on a 60 GB ssd with full encryption. My PC has 16 GB of RAM.

This has resulted in a swap size approaching 16 GB. Can I subsequently change this to 2 GB or completely turn swap off. I need more space for programs and files instead of swap.

I never use hibernation mode.


You can turn off swap with command

sudo swapoff -a  

After that you can resize or delete existing or do something ... If you only resize swap probably you do not have to made some change in /etc/fstab/

Swap can be added like swap file. Try with this command to add swap of 2 GB

dd if=/dev/zero of=/swapfile bs=1k count=2048k
mkswap /swapfile
swapon /swapfile
/swapfile none swap sw 0 0

Edit 1

On the following link you have manual to re-size encrypted partitions, also here
