Gnome 3.2 - How can I completely disable Suspend?

["Adam Sailer" <ASailer uwb edu>]

I've downloaded and installed from the openSUSE-based Gnome 3.2 live disk.

Laptop model is Dell XPS M1330
Video is NVidia GeForce 8400M GS
Kernel ver is 2.6.37.6-0.7-default x86_64

1 - Nouveau driver TANKS when system goes to suspend. Comes back with black
screen and mouse pointer. Must ctrl-alt-backspace to reset X-server.
2 - NVidia driver repository driver ver 275.21 TANKS when system goes to
suspend. Desktop comes back, but is completely frozen except for the mouse
pointer. Must ctrl-alt-backspace to reset X-server.
3 - NVidia's latest driver ver 280.13 causes random lock-ups. Completely
unusable.

UPDATE:

Also noticed that the wireless network adapter is unusable after attempting
to resume from suspend, and the system's fan spins up during suspend
transitions.

I've experimented by uninstalling pm-utils; this has resulted in Gnome 3.2
menu replacing "Suspend" with "Power Off"; this also changes screen settings
from "Suspend  after" to "Turn off after". Once this time-limit is reached,
Gnome becomes unresponsive and ctrl-alt-backspace is required.

Why does this menu not have a "NEVER" option? This might be fine-and-dandy on
a tablet, but these issues prevent me from using Gnome 3+ on any machines
that I do work on...

Thank you,

Adam
