How to automatically mount swap partition?
Solution 1
This is your previous /etc/fstab
:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda2 during installation
UUID=33a0fc77-06b0-406c-95fd-15bf7033b619 / ext4 errors=remount-ro 0 1
# a swapfile is not a swap partition, no line here
# use dphys-swapfile swap[on|off] for that
Now, to add your swap partition to it, do the following:
-
Open Gparted.
-
Right-click on the swap partition and click on Information.
-
Note down your UUID.
-
Now, modify your previous
/etc/fstab
, by doing the following:-
Open the file by typing the command:
sudo -H gedit /etc/fstab
-
Then, add this line,
UUID=THE UUID YOU OBTAINED FROM ABOVE none swap sw 0 0
after the line
# a swapfile is not a swap partition, no line here
Save the file and restart your computer. Everything should be working now.

Solution 2
Type in terminal:
gnome-disks
Then select the swap partition. In the settings menu select "Edit mount" option.

I didn't use a swap partition during installation so now that my ubuntu is installed, I used GParted Partition Editor to create an unallocated partition which I formatted as linux-swap. It didn't automatically mount so I right clicked it and selected swapon. Now, whenever I boot the laptop, the partition is not mounted automatically. Swapon still works but if the partition isn't mounted at boot, its as good as useless. I saw some answers which said to edit some file named Fstab, but I'm not sure about what changes to make... Please help me by giving step-by-step instructions as I'm a TOTAL noob and don't know U of Ubuntu, I'm having a lot of problems... please help me! :'( :( Here's what my fstab file contains-
# /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> # / was on /dev/sda2 during installation UUID=33a0fc77-06b0-406c-95fd-15bf7033b619 / ext4 errors=remount-ro 0 1 # a swapfile is not a swap partition, no line here # use dphys-swapfile swap[on|off] for that

mikewhatever over 8 yearsCan you post the output of
sudo blkid
. It will show the UUID of the swap partition, and we can then add it to /etc/fstab.
