В Ubuntu 16.04 LTS я успешно использовал следующее, чтобы отключить приостановку:
sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.targetИ это для того, чтобы снова включить его:
sudo systemctl unmask sleep.target suspend.target hibernate.target hybrid-sleep.targetОт man systemctl:
mask NAME... Mask one or more units, as specified on the command line. This will link these unit files to /dev/null, making it impossible to start them. This is a stronger version of disable, since it prohibits all kinds of activation of the unit, including enablement and manual activation. Use this option with care. This honors the --runtime option to only mask temporarily until the next reboot of the system. The --now option may be used to ensure that the units are also stopped. This command expects valid unit names only, it does not accept unit file paths. unmask NAME... Unmask one or more unit files, as specified on the command line. This will undo the effect of mask. This command expects valid unit names only, it does not accept unit file paths.
