...it cannot sleep...

Hi,

I am using GENTOO, which I update about once a day.

I have installed sys-power/hibernate-script-2.0-r1

As source for this package 
Homepage:            http://www.tuxonice.net/
is mentioned.

My system consists of:

 Kernel > Linux 3.2.5 (vanilla kernel) 
 CPU    > AMD Phenom(tm) II X6 1090T Processor AuthenticAMD GNU/Linux
 MOBO   > ASUS Crosshair Formula 4 
 GRAKA1 > VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 430] (rev a1)
 GRAKA2 > VGA compatible controller: NVIDIA Corporation GF110 [GeForce GTX 560 Ti] (rev a1)

The GT430 Graka is used for desktop perposes - it is connected to my
monitor. The GTX 560 Ti is used for rendering purposes only. It is not 
connected to any monitor.

As I had installed only one of the Graka, there were no problems to
hibernate the desktop pc. This was valid for both cards.

As I had installed both cards to not to "lock" my desktop while
rendering, peace was over...no sleep was the result.

When I try to hibernate my PC to disk, the script runs until the
monitor goes black. But the computer does not shut off and when I
reboot it, it does not behave as it had been hibernted.

Since the script runs until the monitor blanks I see no chance to get
hands on the last lines of the output of the script.

What can I do to re-enable the hibernation capabilities of my PC?

Thank you very much of any help in advance!

Best regards,
mcc
