The logout screen in Lubuntu 12.04 has several options. I'd like to remove or inactivate the "suspend" and "hibernate" options. Is that possible?

As far I as know you cannot remove/change them (unless you edit the source code and recompile).
To disable suspend / hibernate, you can edit /usr/share/polkit-1/actions/org.freedesktop.upower.policy.
After this the suspend / hibernate are still in the Lubuntu logout window, but if you click them they do nothing (other than lock you out and you need to re-enter the password).
The content that need to be edited is between <default> and </default> for both suspend and hibernate: change (a) <allow_inactive>no</allow_inactive> to <allow_inactive>yes</allow_inactive> and (b) <allow_active>yes</allow_active> to <allow_active>no</allow_active>.
It should be noted that these changes could be nullified by subsequent updates. A way to work around that is to set up a policy as described by the answers here.
