Apparently, the new version of Unity is based on Gnome 3. Apparently, Gnome 3 decided to do away with a huge chunk of the options available to me.
It used to be that when I went to System Settings -> Power Settings, I could keep my screen from going dim when idle -- and things like that. Is there any way for me to change those settings now? Or am I doomed to have my screen go dim when I let my computer go for five seconds?
