There are two types of swap in Linux: swap partitions and swap files.
The OS I chose to disable swap on is Ubuntu, but I think this will work under any Linux distribution (at least under Debian derived distributions).
swapon --show
This will show you which type of swap you have in your system that will be used in the next step.
An example output:
NAME TYPE SIZE USED PRIO
/dev/sdb1 partition 14,9G 3,7M -2
If the swap is found on a partition, run:
sudo swapoff /dev/sdb1
Or if the swap is found within a file, run:
sudo swapoff /swapfile
Then
sudo rm /swapfile
Note: After you run the command above you must run the 3rd step or your system might fail to boot!
The swap info is found in /etc/fstab file.
sudo nano /etc/fstab
Search for the line that has swap text in it and comment it out.
Example:
UUID=606c8e0e-f961-495b-98a4-1034ad079341 none swap defaults 0 0
becomes
# UUID=606c8e0e-f961-495b-98a4-1034ad079341 none swap defaults 0 0
