I am completely new to raspberry pi. I managed to install Raspbian on the pi and got it running. The problem i am facing is that everytime i start the pi, i need to expand the file system to full sd, otherwise the gui is displayed in a smaller window. Is this normal behavior for pi? Do we have to expand file system everytime on startup. If yes, is there any way so that is expands the file system automatically on startup?...........And if this is a problem then how can i solve it?......................I am using the new quad core model (Raspberry pi 2 1GB)
