Disable swap

If you have GParted open, close it. Its Swapoff feature does not appear to to be permanent. 

 Open terminal and become root (su); if you have sudo enabled, you may also do for example sudo -i; see man sudo for all options): 

  sudo -i (Or use sudo for each command) 

 Turn off the particular swap partition and / or all of the swaps: 

 swapoff --all 

 Make 100% sure the particular swap partition partition is off: 

 cat /proc/swaps 

 Open a text editor you are skilled in with this file, e.g. nano if unsure: 

 nano /etc/fstab 

 Comment out / remove the swap partition's UUID, e.g.: 

 # UUID=1d3c29bb-d730-4ad0-a659-45b25f60c37d    none    swap    sw    0    0 

 Open a text editor you are skilled in with this file, e.g. nano if unsure: 

  nano /etc/initramfs-tools/conf.d/resume 

 Comment out / remove / change with 'none' the previously identified swap partition's UUID, e.g.: 

 RESUME=none 

 If your swap is encrypted, do the same with /etc/crypttab.
