12.04 pm-suspend wol problem

[wojb]

Hi
I have issue as folow.
I'm on Ubuntu desktop. I use pm-suspend and wol to work remote on my mashine.
Before I stood on Ubuntu 10.04 and all mentioned procedures work excellent.
Since I move to 12.04 (64bit) problems occure.
If I suspend mashine from system menu I can wakeup it from power button,
but I cant wakeup it from wol.
If I suspend mashine from terminal with pm-suspend I can wakeup mashine either with
power button and wol, system wakeup maybe 1-2 times and in next attempt it doesn't.
Mashines start, but monitors (I have to monitors) are dead - diode on them blinking.

I guess it's graphic drives fault (ATI Radeon HD 3300)
so I tried with proprietary ATI drivers as folow:

but its doesn't solve the problem.

I see to ways to solve the problem:
- try to find out what is wrong with pm-suspend and graphical,
- tune suspend from system menu to suspend with wol capability.

And here is my questions accordingly:
- how to do this :)
- what is the command that I can use in terminal to suspend in menu suspend manner,
and how to tune it to make wol possible.

Best Regards
