Suspend/hibernate menu options missing from KDE

[Kumar Appaiah <a.kumar@alumni.iitm.ac.in>]

Dear Debian User,

I am using a Jessie, and largely have KDE 4.11.

I am trying to configure my KDE to allow sleep on lid close and such
goodness. In the Power Management section of my KDE System Settings, I
am unable to find any sleep/suspend options. Likewise, the K Menu's
Leave section also has only "Restart" and "Shut Down" in the relevant
sections. However, sudo pm-suspend and sudo pm-hibernate and sudo
pm-suspend, indeed, do what I want.

>From searching online, I found that the output of both of these
commands in "false":

qdbus org.freedesktop.PowerManagement /org/freedesktop/PowerManagementorg.freedesktop.PowerManagement.CanHibernate
qdbus org.freedesktop.PowerManagement /org/freedesktop/PowerManagement org.freedesktop.PowerManagement.CanSuspend

In addition, my /etc/default/acpi-support has this:
ACPI_SLEEP=true
ACPI_HIBERNATE=true
LOCK_SCREEN=true
LID_SLEEP=true
#LID_SHUTDOWN=true
DISPLAY_DPMS=xset
XRANDR_OUTPUT=LVDS
#DISPLAY_DPMS_NO_USER=true

However, closing the lid only locks my screen, and doesn't "suspend"
my computer.

Would you be able to suggest something?

Thanks.

Kumar
