Since I updated my Ubuntu to version 12.10, after booting, when Ubuntu starts loading, screen goes off (monitor shows information that no signal is recieved). When screen goes on, first thing I can see is login screen, so I conclude that screen is off in time, when Ubuntu logo with four dots should be shown.
It's nothing very important, but a little unaesthetic, so it would be nice if there's any solution to this problem.
Thank You all for the answers.
