Xfce as your Linux desktop environment, you may find the window controls not quite as you'd like them. Fortunately the lightweight desktops Xfce and LXDE both feature the ability to arrange buttons and controls as you wish.
Going to Application -> Settings -> Settings Manager -> Windows Manager, there's an area in the middle of the panel where you can drag and drop or hide window controls to create your ideal button layout.
You will need to check the themes you're using, as some themes allow for customization of the windows buttons, while others don't. You can install more Xfce4 themes from either the Software Center (Ubuntu and Mint users)/Synaptic Package Manager or you can go to direct to http://xfce-look.org/ and browse the galleries of eye-candy.
