Enable_Swap_on_ubilinux - up-board/up-community GitHub Wiki
The ubilinux™ installer does not enable Swap by default as it is not recommended to use with Flash memory chips (eMMC, SDcard, SSD).
If you still need to use Swap for a specific reason, you can still enable using a simple procedure as the one described on this page where we are going to enable a 1GB Swap file.
From the ubilinux desktop, open a terminal window and type the following steps:
sudo dd if=/dev/zero of=/swapfile bs=1G count=1
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
To verify that your Swap is enabled you can use the command free or
sudo swapon -s
To make the Swap file available at boot edit /etc/fstab
to include the following entry:
/swapfile swap swap defaults 0 0
Save and close and reboot your system to verify that the Swap file is enabled at boot.
