From Ubuntu 11.10, I installed Gnome 3 Shell on my desktop computer. I studied it for a while, and then looked for the button to close the shell, but found only a suspend button. I clicked it and it shut everything down, but it left the computer still on.
I didn't know the resume procedure, so I turned off the power for several seconds to reboot. When I turned the power back on the drive light flickered a few seconds and then the computer came back to the way it was before I tried to reboot. I tried this reboot a couple of times with the same results both times.
Can someone please tell me how to get out of this?
