I've just installed the version 12.04 of ubuntu, and the installation was succesfull, then it asked me to restart computer, everything normal, but when it started again, ubuntu asked for username and password, and then, after I typed them and entered, instead of showing the desktop, it's just showing the default rainbow like picture of ubuntu. I can move the mouse fluidly, everything seems normal but it's just waiting there, doing weel, nothing. So i thought about switching off, and when pressing the button, it asked me "are you sure you want to switch off?" which, I believe, was kind of strange cause it was "frozen-like".
So what should i do now ? is there anything like the task manager on ubuntu ? or something i could open to see what's wrong ?
PS : first time using ubuntu
