Ok, I switched over to gdm and gnome and have similar problems.  It
suspends but does not resume.  So, I've been trying to work it out in a
terminal.  What I've discovered is that I can enter this and it works:

sudo pm-suspend --quirk-dpms-on --quirk-vga-mode3
--quirk-reset-brightness --quirk-vbe-post --quirk-vbemode-restore
--quirk-vbestate-restore

However, when I hit the suspend button, hal initiates the quirks in this
different order:

--quirk-dpms-on --quirk-vbestate-restore --quirk-vbemode-restore
--quirk-vga-mode3 --quirk-vbe-post --quirk-reset-brightness

so, if I try it in a terminal, it suspends but does not resume (same
result as suspend button):

sudo pm-suspend --quirk-dpms-on --quirk-vbestate-restore
--quirk-vbemode-restore --quirk-vga-mode3 --quirk-vbe-post
--quirk-reset-brightness

Now, I believe the problem is that my nvidia driver does not support the
vbetool.  But, why it works in the different order is puzzling to me.
Did you know that order matters?

Also, I have tried and successfully resumed from:

paul :~$ sudo pm-suspend --quirk-dpms-on --quirk-vbestate-restore
--quirk-vbemode-restore --quirk-vga-mode3 --quirk-reset-brightness

and successfully from:

paul :~$ sudo pm-suspend --quirk-dpms-on --quirk-vbestate-restore
--quirk-vbemode-restore --quirk-vga-mode3 --quirk-reset-brightness
--quirk-vbe-post

This makes me think that  --quirk-vbe-post is the problem, but only is
ok in certain orders.  I'm not sure I have enough time to try all the
combinations?

Also, I have gone back to kdm and kde and have the same experience in
the terminal, so there's not a problem in kde

Now that I know that, is there someplace I can config which quirks are
called and in what order?
