Swapfile size is 2G. What would be the best size to allocate to it?
This is a followup question to my original question related to the Ubuntu 19.10 freeze where I had to restart the machine every time.
I looked up at my swapfile and it is of 2G size. I do have a 16G of RAM. But the memory that is being used by the swapfile is '0'. I don't understand what is going on with this.
$ swapon
NAME TYPE SIZE USED PRIO
/swapfile file 2G 0B -2
$ free
total used free shared buff/cache available
Mem: 16383568 2503164 11927228 477108 1953176 13073208
Swap: 2097148 0 2097148
The following is the image. Can some one help me with this?

Update 2: The following are the results of systcl vm.swappiness and grep -i swap /etc/fstab
~$ sysctl vm.swappiness
vm.swappiness = 60
~$ grep -i swap /etc/fstab
/swapfile none swap sw 0 0
Update 3: Added the result for ls -al /usr/share/gnome-shell/extensions
- Did not have the folder extensions under /.local/share/gnome-shell
$ ls -al /usr/share/gnome-shell/extensions

Update 3: Here I am attaching the drivers I am using for the NVidia. I have tried 435 but I kept on seeing some display issues with it. They come and go. They are something like this.
Now I tried the 430 in the drivers section. This seems to work fine so far. I have seen those out of order pixels but very rarely. What could be the reason for this? And I tried installinng the newly release 440 drivers for the nVidia but it kept on failing and therefore as a lost resort I had to move back to 430.
I would say to just leave it as is. The swap file is a file stored on your hard drive or SSD that is used as a place for inactive data in your RAM when your system is running low on RAM. Also, by the looks of it, your system isn't using the swap file at all. This is because you probably aren't using that much RAM, so your system doesn't need to use the swap file. However, you should keep it to give your system a buffer if it's running low on RAM, just in case you ever do something RAM intensive. Besides, resizing/deleting your swap file is kind of complicated, and is only necessary for very specific use cases.
