Enable zram on Ubuntu 20.04 on DigitalOcean

Raw

The Ubuntu 20.04 image appears to come without extra modules, so they need to be installed additionally:

$ sudo apt install linux-modules-extra-$(uname -r)

Then simply install zram-config

$ sudo apt install zram-config

And then reboot.

Verify that zram is working:

cat /proc/swaps 
Filename				Type		Size	Used	Priority
/dev/zram0                              partition	500180	82688	5

If you see the /dev/zramX devices in the output, it worked.
