I am looking to create a shortcut of the default "suspend to disk" command used in KDE4.3.
(the suspend to disk choice hidden in ctrl+alt+del)

Any idea ?

Looked at:

No success with qdbus.

This is controlled by KSMServer. It has a D-Bus interface, but unfortunately I do not know how to operate it.

Not being able to make such operation which should be very simple is a problem.

The "suspend to disk" command is very hidden, and not so convenient to use.
Still looking for a qdbus specialist.

And another question:
Where are hidden the command of "kmenu > leave > sessions/system choices" ??
I don't find a way to edit the hybernate shortcut.

If you use Powerdevil, then the following will work:

- Suspend to RAM

Code: Select all

qdbus org.kde.kded /modules/powerdevil suspend 1

- Suspend to Disk

Code: Select all

qdbus org.kde.kded /modules/powerdevil suspend 4

No I don't.
No uswsusp, no Powerdevil, no ACPI package (just BIOS + kernel ACPI).
The default "suspend to disk" works with no extra.

Kernel info:

Hibernation (aka 'suspend to disk') (HIBERNATION)

Enable the suspend to disk (STD) functionality, which is usually called "hibernation" in user interfaces.
STD checkpoints the system and powers it off; and restores that checkpoint on reboot.

You can suspend your machine with 'echo disk > /sys/power/state'

'echo disk > /sys/power/state' works (as root), but does not behave the same as the KDE4 default command.

Still to be clarified.

Probability is high that the default "suspend to disk" KDE4 command is:
/usr/sbin/pm-hibernate

Not sure if things have changed from here since Aug 05 2009 but for Suspend to Ram I had to use:

Code: Select all

qdbus org.kde.kded /modules/powerdevil suspend 2

Good tip, bcooksley. Thanks.

Thanks bcooksley

qdbus org.kde.kded /modules/powerdevil suspend 4 works nicely... now i can assign reassign one of extra keys on my keyboard for one touch Hibernation
