My notebook failed to recover from hibernation. I was able to get into
the machine by ssh, but the screen didn't function.

I saw the following in my "ps aux" listing:

I found the following page:

https://wiki.ubuntu.com/NvidiaLaptopBinaryDriverSuspend

Following its suggestions got hibernate working. Note, it worked without
the NvAGP line in xorg.conf, so it was only changes in /etc/default
/acpi-support that were required.

If you need more info, please ask.
