The point is I want to have exactly like ubuntu gui. or windows gui. Same desktop and normal. but it is just terminal. The joomla CT is working but the ubuntu's ct terminal is not. Whatever I type, nothing happens.
which template is this based on?
I only use CTs as server (headless) machines, and I always got a CLI, ie what I expected...
did you try to just press "enter"?
[edit]
this?
