Change the screen resolution thru commandline, using xrandr

Once I changed my screen's resolution to a very small value and as a result I wasn't able to see the drop down box of the GUI application to change it back. This was when I came to know about Xrandr, a great command line application to configure X11 server. Well, there are a lot of things it can do but if you ever want to change the resolution, use this command.
