Entirely disable suspension (at kernel level? - has to be independent of used DE and login state!)

Solution 1:

I found the solution on Server Fault:

We have to create an executable script in /etc/pm/sleep.d/ that will cancel any hibernate or suspend actions.

sudoedit /etc/pm/sleep.d/000cancel-hibernate-suspend

The content of this file should be:

#!/bin/sh
# prevents hibernation and suspend
. "$PM_FUNCTIONS"
case "${1}" in
  suspend|hibernate)
    inhibit
    ;;
  resume|thaw)
    exit 0
    ;;
esac

Now make that file executable:

chmod 0755 /etc/pm/sleep.d/000cancel-hibernate-suspend

Entirely disable suspension (at kernel level? - has to be independent of used DE and login state!)
