(Note: It will ask for a administration password, or your own account password, type it and press Enter.)

2. From GParted, right-click then click Information. What we are looking here, is UUID information. That we going to used to activate permanently the Linux-Swap File System.

4. To make the new linux swap becomes activated and permanent, even you restart your computer, you must edit the fstab file. On the temporary text with the new swap uuid, copy it then, erase the old uuid on the fstab file, then paste the new uuid. (see the picture)
