I just mentioned one of the big problems we discovered was that hibernating the client would cause the server to hibernate or sleep. To discover how to disable hibernation, I thought the quickest way would be to jump on the the freenode channel of Edubuntu, irc://freenode/edubuntu, then the much more active Ubuntu one, irc://freenode/edubuntu. On the Edubuntu one, I discovered that I had to change a hibernate setting in gnome-power-manager. The Ubuntu one helped me locate it; I had to enter gconf-editor in the terminal, find gnome-power-manager, and then uncheck can_hibernate. One problem solved thanks to the support from the community!
Exellent!, still apply for ubuntu 8.10
