[Bug 53060] Re: HP Compaq nw9440 - hibernation problem

[Peter Funk]

Regarding Hibernation:  This now seems to work for me:

I've added the following two lines to /etc/modprobe.d/options :

# http://wiki.beryl-project.org/wiki/Troubleshooting_nVidia#Suspend2
options nvidia NVreg_SoftEDIDs=0

I've also added the psmouse module unloading/loading script 
suggested in 
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.17/+bug/53059/comments/11

During the last four test cycles my system went into hibernation and
returned from hibernation without problems.  Even the acpi power 
state is detected correctly after resume with Kernel 2.6.20-15-generic
(Default in 7.04 feisty).

What still doesn't work is ACPI Standby/Sleep.  I've tried both
ACPI_SLEEP_MODE=mem and ACPI_SLEEP_MODE=standby in
/etc/default/acpi-support.  The system goes into a sleep mode
with only the power stwitch LED flashing once per second.  
But returning to on state requires typing the power switch 
and causes the system boot from scratch.

Peter.
