More like 'in the packages'.

None of these.
Laptop-mode-tools is for powersaving.
uswsusp and tux-on-ice do not do anything that kernel cannot.
powerdevil is a KDE GUI tool that cannot work unless underlying things do.
acpid is irrelevant to the suspend-on-disk.
hibernate is tux-on-ice related.

Remove all those save for laptop-mode-tools and powerdevil.
Ensure you have swap configured.
Invoke 'systemctl hibernate' if you're using systemd.
Install pm-utils if not, and invoke 'pm-hibernate'.
