How can I remove the Suspend and Hibernate options from the power menu?

I want to get rid of the Hibernate and Suspend options on the top-right menu in Unity. These do not work on my netbook and having them close to "logout" is not useful.

I assume you're using a much earlier distro since this post is apparently from 5 months ago. Anyway, I just did the opposite of what you're doing yesterday on Precise. Run the following command to open the file to edit:

sudo gedit /var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla

Scroll to the bottom. Check to see if the following information exists, and if not add them:

[Disable hibernate]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=no

[Disable suspend]
Identity=unix-user:*
Action=org.freedesktop.upower.suspend
ResultActive=no

Doing this makes those options do nothing when you click them; they will disappear from the menu after you restart your computer.
