Thanks
it wont allow me to create a swap space saying the partition is already mounted. there no unallocated space when i erase disk. i clicked swap with no hibernate but was surprise swap was not created
I also try to re-size my partition with no luck
create/use a swap file
If you did that you should already have one. Or a (maybe rather small) swap partition.
Why you apparently don’t have one, as you say - I have no idea.
But creating and integrating a swap file is easy - without having to shuffle around your partitions.
that means that there is no dedicated swap partition
there could still be a (rather small) swap file
edit:
gparted would not show this
the commands:
free
or
top
would show it …
as well as:
swapon --show
/edit
Hi.
There are two types of swap: partition (as separated filesystem) and swapfile. If you already have a partition is mandatory to unmount it first and then reformat and convert it to swap type (82) before using it as swap. You can also create a swapfile and use the existing partition for something else.
In order to see your swap, open your terminal and issue:
sudo swapon --show
Empty means no swap, anything else the type/location or your swap.
Thanks there is a small swapfile
NAME TYPE SIZE USED PRIO
/swapfile file 512M 2.3M -2
I really dont know why my Laptop runs very very slow once am on the virtualbox and it takes about 3mins to boot my laptop
create a bigger one - if that 512M one is not enough
adjust the UUID in /etc/fstab afterwards
swapoff
the currently used swap first … before creating a new one with the same name …
That “long” boot time is … normal
for rotational disks
adding/changing the amount of swap will not help here
all the needed data needs to be read from the hdd - it takes time …
virtualbox is:
starting another OS
from within a already running OS
it takes away from the system RAM - and it also takes time
… to “scrape” the data off the hdd …
use ssd if you want it to be faster 
accessing huge rotating disks is slow
particularly with a often changing/updated system like Manjaro/Arch
… nothing is/stays contiguous - read times increase with updates
… that is what it feels like to me - it is my experience
quite a long boot time,
then quite a long time from login to DE,
then … quite long time to load the browser …
3 minutes easily …
but totally normal - with a rotating disk …
more swap will not change that
the limiting factor is simply disk access time
