Hi. I just installed Ubuntu 12.10 in my computer and then installed sage for Ubuntu 12.04 (I am very new to both Linux and Sage). I can open Sage in my machine using the notebook interface, but, for one thing, it doesn't plot. I copied bellow what I get when I enter 'plot(x^2)'. Any help will be appreciated. Thanks!
