From Ubuntu 18.04 onwards, a swapfile rather than a dedicated swap partition is used. The swap file is named "swapfile". To change the size of this swap file:1. Disable the swap file and delete it (not really needed as you will overwrite it)sudo swapoff /swapfilesudo rm /swapfile2. Create a new swap file of the desired size.Determine the size of your swap file. If you want to make a 4 GB swap file, you will need to write 4 * 1024 blocks of 10242 bytes (= 1 MiB). That will make your count equal to 4 * 1024 = 4096. Create the file of this size with the command:sudo dd if=/dev/zero of=/swapfile bs=1M count=40963. Assign it read/write permissions for root only (not strictly needed, but it tightens security)sudo chmod 600 /swapfile4. Format the file as swap:sudo mkswap /swapfile5. The file will be activated on the next reboot. If you want to activate it for the current session:sudo swapon /swapfile
With 12GB of ram, do I even really need a swap file or partition ?(I have never seen my ram usage even come close to 4GB)
When Linux Lite is installed, does it automatically create a swap file ?And if so, what size is it and where is it located ?
