Install zram compressed swap on Ubuntu:
========================================
Instead of using disk space for swap contents, you can try to compress contents in ram instead. Does use some CPU usage though.

1. Check what swap partitions you have:
cat /proc/swaps

If there is no /dev/zram0, continue on.

2. edit the /etc/fstab file to remove old swap partition and file since there are no longer used.
*Also run swapoff -a to un mount any old swap partitions.

3. Install this package:
sudo apt install zram-config

4. Once installed, reboot the system. You should now have zram enabled!
*Can prove by running this command: cat /proc/swaps
