As I said in a previous posting, I used:
# echo 8589934592 > /sys/power/image_size
# echo platform > /sys/power/disk; echo disk > /sys/power/state
Mow I'm wondering what to use instead.

The s2ram tool allows you to suspend the system to RAM and restore the state
of the graphics adapter after the resume automatically. For this purpose it
uses the code out of vbetool and radeontool utilities, needed for handling
quite a lot of graphics cards after the resume from RAM.

Then why doesn't uswsusp depend on either vbetool or radeontool?

How do hooks work?

hibernate is called, several things happen:

So this readme doesn't tell you how to suspend to disk ... There's a
package "hibernate", but that seems to be yet another tool for the
same purpose.
/etc/pm/ is only a directory containing other directories.
Do I have to take it that there's no Debian way of suspending to disk
(unless you use gnome maybe)? It's a feature that should work out of
the box, like another option for the shutdown command ("shutdown -std
now", for example, to suspend to disk) ...

It would have to do that not only on installation. What if you install
it and use it and then a year or half a year later you upgrade from,
let's say, 4GB to 8GB of RAM? You'd have to remember that at some
point, you had to set up the suspend to disk stuff according to your
RAM-size and adjust ...
