The main things that happen are as follows:
When I attempt to suspend (via MATE's GUI anord "pm-suspend" in the commandline), the PC appears to shut off but the monitor still has backlight while the light on the tower's power button is still on. Pressing the power button, the keyboard and mouse all have no effect. I am forced into a hard-reset holding down the power button. Although I read many others reporting this, I've yet to have any success using advice in the threads they were discussed in.
Hibernate (via "pm-hibernate" in the Terminal, don't see the point of setting it up in MATE until this is resolved) is the same, but when I turn the machine on it is usually able to restore my session.
Based on my experience with the guide in http://www.mjmwired.net/kernel/Document ... ugging.txt, suspend fails at the "platform" test, while hibernate fails at the "devices" test unless I use CTRL+ALT+F1 to change to another virtual terminal and use "sudo service mdm stop && rmmod nvidia" to stop the GUI session and unload the nvidia driver. After that, hibernate passes the "core" test as described in the guide linked in this paragraph.
Is there anything I can do to get these features working? I'll happily repeat any of this work and gather any output requested. Thanks in advanced.

EDIT: It's my understanding that there's a feature called PM_TRACE that can diagnose this problem, but it's only available to a 32-bit kernel (as the subject states, I'm on a 64-bit install). I'd rather not make a mess as my father depends on this machine.
