When I press shut down, it sometimes logouts instead. After that, I have to login again. Shortly after the desktop appears again, whole screen goes black and there is only a white blinking underscore in the top left corner. After that, nothing more seem to happen. I don't know how long this lasts for, I never had more than a few minutes. (When I am in haste, I really don't want to wait for such things.) I always turned it off by holding the power button when this appeared.
Is there any way to remove this "feature"? It is annoying.
sudo shutdown -h nowfrom the command line when you want to shut down? Does that work or still the same problem?
