Suspend - which packages are at least needed?

[Hans <hans.ullrich@loop.de>]

Hi folks,

in earlier times suspend-to-disk worked fine, but now after the years things 
changed. Suspend-to-disk is no more working. This might be by changes in the 
kernel and in the packages.

So I want to do a fresh configuration for susspending. 

What packages do I really need? On my debian/testing I have

laptop-mode-tools, uswsusp, tux-on-ice, powerdevil (Plasma5),acpi and 
hibernate. 

I believe, these might be too much. Any ideas?

Thanks for any hints.

Best

Hans
