The Windows Manager and its functionality

December 15th, 2009 admin Posted in Uncategorized | No Comments »

Window managers, like GNOME’s Sawfish window manager, are programs that receive commands indirectly from the user through mouse clicks and key strokes. The window manager passes those commands to a set of graphics libraries, which then communicate with the X server to manipulate windows on the graphics device (usually your monitor screen).
The window manager acts like a playground monitor; it’s the central point of control for the major windows seen on the screen (and even some windows that can’t be seen). It blows a whistle when a window gets unruly. The window manager can serve also as a desktop, where you can use it to launch applications. A window manager isn’t necessary, but it would be difficult to use more than one or two applications at once without also using a window manager. (The applications themselves would need to be written to allow resizing, window positioning, and so on.)
Window managers may also maintain an icon bar, which keeps icons easy to find and manage, as well as performing other functions. But the most important thing to remember about window managers in X is that they are just user-level programs like any other — they are not part of the system. You have a choice of window managers, and each has different capabilities, although a discussion of window managers other than GNOME and their capabilities is outside the scope of this book.
The Red Hat Linux For Dummies CD-ROMs contain several window managers including the GNOME Sawfish window manager KDE and the previous Linux standard Fvwm. GNOME is the default for Red Hat Linux and so GNOME is the window manager used in this book KDE is similar to GNOME in that it is a modern system but we leave it up to you to explore if you wish. You can also use good old Fvwm to start applications (and stop them of course), move windows, shrink windows, expand windows, and do everything but wash windows. Just think, you can use your system without ever typing a command!
