You scrounge the web looking for things that people have done on
systems like yours, try them all in various combinations, and pray :(
[It's ridiculous how many arcane things there are that one might need
to tweak, and then you'll still probably experience occasional and
seemingly-random issues, like a disappearing wired ethernet adapter or
stopped bluetooth deamon].  There is a better way, but only if you use
Windows or MacOS :(


On my T60p running Feisty, suspend-to-RAM mostly works for me by
changing

    POST_VIDEO=true

  to

    POST_VIDEO=

in /etc/default/acpi-support.  You might see the note I entered here:

also, note that apparently the gnome-power-manager applet's suspend
function apparently is somewhat different from the one you get in the
window that results from hitting the "log out button!"  I only seem to
have the "shutdown when re-docking" problems mentioned above when I
use the former.

I used to have SWSUSP2 working with Dapper under an earlier kernel
(which I had re-compiled myself).  When it works, it's pretty reliable
and pretty wonderful.  Haven't had time to do it with this kernel.

Cheers,
