Comment # 2 on bug 1185928 from Archer Allstars

I voted to make a change to this script, as creating zRAM devices based on the
number of CPU cores can cause an issue too. See
https://github.com/Nefelim4ag/systemd-swap/issues/176

It's a deprecated practice which can do more harm than good.

For anyone who want to fix this issue, you can do this by:

1. Open your file manager as an admin. Mine is: nautilus admin:///
2. Search for zramswapon file, edit the # get the number of CPUs to num_cpus=1.
3. Do the same for zramswapoff file.
4. Reboot your PC. Check zRAM with: sudo zramctl, now you should only have 1
zRAM device.
