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

[Sitsofe Wheeler]

Nicola:
Thanks for the detailed information.

Since caps lock appears to still be working it sounds like your
display's backlight is not being turned back on (so effectively the
state of your card isn't being perfectly restored). However since you
say that this worked correctly when you were testing the nv driver it
sounds like an issue with the NVIDIA binary driver.

This is where things get complicated with of ifs and ands and buts.
There is a small chance you may be able to get hibernate working IF your
card is connected via agp AND the NVIDIA driver carries an agpgart for
your card BUT there are no guarantees. You will need to disable your
usual agp module and edit your xorg.conf (back it up first!) in order to
test this but it's hard to know if you will be successful. See
http://en.opensuse.org/NVidia_Suspend_HOWTO , the steps there don't fit
your exact case (e.g. Ubuntu has a /etc/modprobe.d/ directory ) so
please be careful. You may also find
https://help.ubuntu.com/community/NvidiaLaptopBinaryDriverSuspend useful
but it is missing the agp module blacklisting step.

Good luck!
