YOu can verify this by starting a job in X that will take a long time and provide a progress bar. Switch away to a VT, wait a few and switch back. The progress bar will have advanced. IOW, the X session is still operating, it has merely been detached from the terminal. This is why you can have fun things like multiple X sessions on one machine with one attached to the local "terminal" (keybd, monitor, mouse) and the others attached to remote terminals via X forwarding or VNC etc. > > The saving of your X session's context makes sense because you will so, its not really saved, but rather it gives up control of the screen to another session. that's just my take on it.
