Edit: the OS waits 1:30min if it can't find the swap file: that's probably most or all of your slow boot.

In gparted, make the swap partition like any other partition, just make it type = "linux swap".
gparted -> rt-click free space -> new -> (window comes up) : "File system: (select "linux swap" from menu).
But I think Mint 19.1 uses a swap file, not a partition, but your fstab file doesn't show that.
If you make a new swap partition, make sure the UUID matches the one in fstab.

According to the FSTAB, you already have a swap partition. It could be that the UUID does not reflect
the actual swap partition. This can (and will) cause delay.
Use Gparted to get information about the current UUID. After that you can use this info to modify the
FSTAB file via a text program. You will have to be Root in order to do that.

Another showstopper might be the file "rc.local" in the "etc" folder. I think it's safe to empty that file,
because most of the commands are now extecuted via SystemD.

I think Mint 19.1 uses a swap file, not a partition ...

FYI, that's true by default, but a swap partition is supported also. Indeed, it's semi-automatic. If a swap partition is present, the installer will use it and set up fstab accordingly.

Swap file or swap partition?
If you made a partition, just change your original line so the UUID (46520,,,e2d0) matches:

Code: Select all

UUID=46520acb-801a-4e6f-a4c5-30fa870ae2d0 none swap sw 0 0

Get the partition UUID with:

Code: Select all

sudo blkid

Make a backup of /etc/fstab, then edit it sudo your-text-editor /etc/fstab
and change
46520acb-801a-4e6f-a4c5-30fa870ae2d0
to the new UUID from blkid.

If it's a swap file, then mine looks like:

Code: Select all

/etc/100MB.swap swap swap defaults  0 0

IIRC, you have to make the file some special, but simple, way...
