X WINDOWS X is the layer between the hardware on your system (your graphics card, and so on) and the GUI that sits on top of X. Have a look at the following diagram to get the general idea: When a program is started up, it goes through the process of first talking to the GUI, about what to do with it's windows, ie: placement, focus and so on. The GUI applies it's thoughts to the process, applies the look, menubars (File, Help, Close, Minimise, etc), and all decorations to the window, then passes it to X. X has the final decision on where it places it on a screen. It then talks to the hardware, making it issue the process.

KDE VS GNOME � DEFAULT LOOK › KDE - by default favors blue and black, has one toolbar at the bottom of the screen, and has one main menu. › GNOME - by default favors brown and orange, has 2 toolbars (one at the top, one at the bottom), and splits menu into three submenus —Applications, Places, and System. � MENU NAVIGATION › KDE - there is a KMenu through which you access all programs › GNOME - you have separate buttons for applications, for folder navigation, and for system preferences. � RENAMING FILES › KDE - also defaults to a single-click instead of double-click for opening files. › GNOME - also focuses on the main file name, but it does so inline and not with a pop-up window.

KDE VS GNOME � SYSTEM PREFERENCES › KDE - has a System Settings central location for configuring system preferences. This can be accessed through the KMenu. › GNOME - by default, you access each preference one at a time by going to System > Preferences > and then selecting the item you want. � CHANGES › KDE - you have to click Apply or Save to get the changes to stick. › GNOME - changes usually take effect as you are choosing the new option. � EXITING › KDE - click on the KMenu and select Leave and then the next option. › GNOME - exit option recently moved from being in the System menu to being its own applet.
