12 This chapter will cover the installation and some configuration of the usual way of giving your Dragonfly BSD system an X-Windows style Graphical User Interface (GUI) and a modern Desktop Environment. In Unix systems, the graphical drawing system is provided by the combination of an X11R6 compliant X-Windows Server, such as the X.org server, and other software such as Window Managers and Desktop Environments. This multi-layered approach may be surprising to people coming from systems like the Mac or like Windows where these components are not so flexible, or provided by so many separately installed and configured pieces.
14 For more information on the video hardware support in X.org, check the [X.org](http://www.x.org/) web site. If you have problems configuring your X server, just search the web. There are lots of tutorials and guides on how to set up your X properly, if the information in this page is not enough for your situation.
16 Before reading this chapter, you should know how to install additional third-party software. Read the `dports` section of the documentation, for DragonFly 3.4 and later.
18 You may find the FreeBSD X Configuration instructions apply exactly and unchanged in DragonFly BSD.
19 They are found [[here|http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/x-config.html]].
25 [X.org](http://www.x.org/) is the most popular free implementation of the X11 specification. The X11 specification is an open standard, and there are other implementations, some commercial, and some free.
27 ### The Window Manager and the Desktop Environment
29 An X Server is a very low level piece of software. It does not provide any way to move windows around or resize them. It does not provide a title bar on the top of your windows, or a dock, or any menus.
31 These things are the job, in the oldest style of X environment, of your window manager, or in more recent times, of a Desktop Environment.
33 Installing X.org by itself does not give you any window manager or any desktop environment. You will have to choose one and install it yourself. Until you select one, your system will not be usable.
35 There are dozens of window managers and desktop environments available for X. The most retro ones you might chose include `fvwm` and `twm` which have that retro 1980s workstation look and feel. There are also window managers included inside modern desktop environments like XFCE, KDE and GNOME.
37 If you are brand new and don't know what to do, select the XFCE desktop environment and follow those instructions.
38 Every desktop environment or window manager also has a different configuration mechanism. Read your chosen environment's documentation to learn more. Some are configured by text files alone, and some (like KDE and GNOME) have sophisticated graphical configuration utilities and "control panels".
40 Note that XFCE, KDE and GNOME are all desktop environments, which already include the corresponding window manager.
44 **X.org** is currently available in the DragonFly dports collection.
52 # cd /usr/dports/x11/xorg/
58 Xorg can often work without any configuration file.
59 The TWM window manager is include by default.
61 You can launch Xorg with TWM by Simply typing at prompt:
65 If this does not work, or if the default configuration is not acceptable, then X11 must be configured manually.
67 You can put your configuration files in /usr/local/etc/X11/
69 See Xorg web site for more information on configuration files.
71 After DragonflyBSD 4.4, for 3D acceleration, you have to add the user running Xorg to video group :
73 # pw groupmod video -m username
75 You can try the command :
79 For generating configuration files in /root/, then copy it to /usr/local/etc/X11/
81 However, -configure option seems broken for some people, please run Xorg without configuration files or create them manually.
83 The X11 configuration process is now complete. You can start **X.org** with [startx(1)](http://leaf.dragonflybsd.org/cgi/web-man?command=startx§ion=1). The X11 server may also be started with the use of [xdm(1)](http://leaf.dragonflybsd.org/cgi/web-man?command=xdm§ion=1).
87 ## The X Display Manager
89 ***Contributed by Seth Kingsley.***
93 The X Display Manager ( **XDM** ) is an optional part of the X Window System that is used for login session management. This is useful for several types of situations, including minimal "X Terminals", desktops, and large network display servers. Since the X Window System is network and protocol independent, there are a wide variety of possible configurations for running X clients and servers on different machines connected by a network. **XDM** provides a graphical interface for choosing which display server to connect to, and entering authorization information such as a login and password combination.
95 Think of **XDM** as providing the same functionality to the user as the [getty(8)](http://leaf.dragonflybsd.org/cgi/web-man?command=getty§ion=8) utility (see [ Section 17.3.2](term.html#TERM-CONFIG) for details). That is, it performs system logins to the display being connected to and then runs a session manager on behalf of the user (usually an X window manager). **XDM** then waits for this program to exit, signaling that the user is done and should be logged out of the display. At this point, **XDM** can display the login and display chooser screens for the next user to login.
99 The **XDM** daemon program is located in `/usr/local/bin/xdm`. This program can be run at any time as `root` and it will start managing the X display on the local machine. If **XDM** is to be run every time the machine boots up, a convenient way to do this is by adding an entry to `/etc/ttys`. For more information about the format and usage of this file, see [ Section 17.3.2.1](term.html#TERM-ETCTTYS). There is a line in the default `/etc/ttys` file for running the **XDM** daemon on a virtual terminal:
103 ttyv8 "/usr/local/bin/xdm -nodaemon" xterm off secure
105 By default this entry is disabled; in order to enable it change field 5 from `off` to `on` and restart [init(8)](http://leaf.dragonflybsd.org/cgi/web-man?command=init§ion=8) using the directions in [ Section 17.3.2.2](term.html#TERM-HUP). The first field, the name of the terminal this program will manage, is `ttyv8`. This means that **XDM** will start running on the 9th virtual terminal.
109 The **XDM** configuration directory is located in `/var/lib/xdm`. The sample configuration files are in `/usr/local/share/examples/xdm/`, in this directory there are several files used to change the behavior and appearance of **XDM** . Typically these files will be found:
112 <tablestyle="width:100%"> **File** | **Description**
113 <tablestyle="width:100%"> `Xaccess` | Client authorization ruleset.
114 `Xresources` | Default X resource values.
115 `Xservers` | List of remote and local displays to manage.
116 `Xsession` | Default session script for logins.
117 `Xsetup_`* | Script to launch applications before the login interface.
118 `xdm-config` | Global configuration for all displays running on this machine.
119 `xdm-errors` | Errors generated by the server program.
120 `xdm-pid` | The process ID of the currently running XDM. |
124 Also in this directory are a few scripts and programs used to set up the desktop when **XDM** is running. The purpose of each of these files will be briefly described. The exact syntax and usage of all of these files is described in [xdm(1)](http://leaf.dragonflybsd.org/cgi/web-man?command=xdm§ion=1).
126 The default configuration is a simple rectangular login window with the hostname of the machine displayed at the top in a large font and "Login:" and "Password:" prompts below. This is a good starting point for changing the look and feel of **XDM** screens.
130 The protocol for connecting to **XDM** controlled displays is called the X Display Manager Connection Protocol (XDMCP). This file is a ruleset for controlling XDMCP connections from remote machines. It is ignored unless the `xdm-config` is changed to listen for remote connections. By default, it does not allow any clients to connect.
134 This is an application-defaults file for the display chooser and the login screens. This is where the appearance of the login program can be modified. The format is identical to the app-defaults file described in the X11 documentation.
138 This is a list of the remote displays the chooser should provide as choices.
142 This is the default session script for **XDM** to run after a user has logged in. Normally each user will have a customized session script in `~/.xsession` that overrides this script.
146 These will be run automatically before displaying the chooser or login interfaces. There is a script for each display being used, named `Xsetup_` followed by the local display number (for instance `Xsetup_0`). Typically these scripts will run one or two programs in the background such as `xconsole`.
150 This contains settings in the form of app-defaults that are applicable to every display that this installation manages.
154 This contains the output of the X servers that **XDM** is trying to run. If a display that **XDM** is trying to start hangs for some reason, this is a good place to look for error messages. These messages are also written to the user's `~/.xsession-errors` file on a per-session basis.
156 ### Running a Network Display Server
158 In order for other clients to connect to the display server, edit the access control rules, and enable the connection listener. By default these are set to conservative values. To make **XDM** listen for connections, first comment out a line in the `xdm-config` file:
162 ! SECURITY: do not listen for XDMCP or Chooser requests
164 ! Comment out this line if you want to manage X terminals with xdm
166 DisplayManager.requestPort: 0
168 and then restart **XDM** . Remember that comments in app-defaults files begin with a "!" character, not the usual "#". More strict access controls may be desired. Look at the example entries in `Xaccess`, and refer to the [xdm(1)](http://leaf.dragonflybsd.org/cgi/web-man?command=xdm§ion=1) manual page for further information.
170 ### Replacements for XDM
172 Several replacements for the default **XDM** program exist. One of them, **kdm** (bundled with **KDE** ) is described later in this chapter. The **kdm** display manager offers many visual improvements and cosmetic frills, as well as the functionality to allow users to choose their window manager of choice at login time.
176 ## Desktop Environments
178 ***Contributed by Valentino Vaschetto. ***
180 This section describes the different desktop environments available for X on FreeBSD. A ***desktop environment*** can mean anything ranging from a simple window manager to a complete suite of desktop applications, such as **KDE** or **GNOME** .
186 **GNOME** is a user-friendly desktop environment that enables users to easily use and configure their computers. **GNOME** includes a panel (for starting applications and displaying status), a desktop (where data and applications can be placed), a set of standard desktop tools and applications, and a set of conventions that make it easy for applications to cooperate and be consistent with each other. Users of other operating systems or environments should feel right at home using the powerful graphics-driven environment that **GNOME** provides.
188 #### Installing GNOME
190 **GNOME** can be easily installed from a package or from dports:
192 To install the **GNOME** package from the network, simply type:
196 To build **GNOME** from source, see the chapter on dports for more information:
198 # cd /usr/dports/x11/gnome
202 Once **GNOME** is installed, the X server must be told to start **GNOME** instead of a default window manager.
204 The easiest way to start **GNOME** is with **GDM** , the GNOME Display Manager. **GDM** , which is installed as a part of the **GNOME** desktop (but is disabled by default), can be enabled by adding `gdm_enable="YES"` to `/etc/rc.conf`. Once you have rebooted, **GNOME** will start automatically once you log in -- no further configuration is necessary.
206 **GNOME** may also be started from the command-line by properly configuring a file named `.xinitrc`. If a custom `.xinitrc` is already in place, simply replace the line that starts the current window manager with one that starts **/usr/pkg/bin/gnome-session** instead. If nothing special has been done to the configuration file, then it is enough simply to type:
210 % echo "/usr/pkg/bin/gnome-session" > ~/.xinitrc
212 Next, type `startx`, and the **GNOME** desktop environment will be started.
214 **Note:** If an older display manager, like **XDM** , is being used, this will not work. Instead, create an executable `.xsession` file with the same command in it. To do this, edit the file and replace the existing window manager command with **/usr/pkg/bin/gnome-session** :
218 % echo "#!/bin/sh" > ~/.xsession
220 % echo "/usr/pkg/bin/gnome-session" >> ~/.xsession
222 % chmod +x ~/.xsession
224 Yet another option is to configure the display manager to allow choosing the window manager at login time; the section on [ KDE details](x11-wm.html#X11-WM-KDE-DETAILS) explains how to do this for **kdm** , the display manager of **KDE** .
226 #### Anti-aliased Fonts with GNOME
228 X11 supports anti-aliasing via its ***RENDER*** extension. GTK+ 2.0 and greater (the toolkit used by **GNOME** ) can make use of this functionality. Configuring anti-aliasing is described in [ Section 5.5.3](x-fonts.html#ANTIALIAS).
230 So, with up-to-date software, anti-aliasing is possible within the **GNOME** desktop. Just go to **Applications->Desktop Preferences->Font** , and select either Best shapes, Best contrast, or Subpixel smoothing (LCDs). For a GTK+ application that is not part of the **GNOME** desktop, set the environment variable `GDK_USE_XFT` to `1` before launching the program.
236 **KDE** is an easy to use contemporary desktop environment. Some of the things that **KDE** brings to the user are:
238 * A beautiful contemporary desktop
240 * A desktop exhibiting complete network transparency
242 * An integrated help system allowing for convenient, consistent access to help on the use of the **KDE** desktop and its applications
244 * Consistent look and feel of all **KDE** applications
246 * Standardized menu and toolbars, keybindings, color-schemes, etc.
248 * Internationalization: **KDE** is available in more than 40 languages
250 * Centralized consisted dialog driven desktop configuration
252 * A great number of useful **KDE** applications
254 **KDE** comes with a web browser called **Konqueror** , which represents a solid competitor to other existing web browsers on UNIX® systems. More information on **KDE** can be found on the [KDE website](http://www.kde.org/).
258 Just as with **GNOME** or any other desktop environment, the easiest way to install **KDE** is through the pkgsrc framework or from a package:
260 To install the **KDE** package from the network, simply type:
264 To build **KDE** from source, using the dports:
266 # cd /usr/dports/x11/kde4
269 After **KDE** has been installed, the X server must be told to launch this application instead of the default window manager. This is accomplished by editing the `.xinitrc` file:
271 % echo "exec startkde" > ~/.xinitrc
273 Now, whenever the X Window System is invoked with `startx`, **KDE** will be the desktop.
275 If a display manager such as **XDM** is being used, the configuration is slightly different. Edit the `.xsession` file instead. Instructions for **kdm** are described later in this chapter.
277 #### More Details on KDE
279 Now that **KDE** is installed on the system, most things can be discovered through the help pages, or just by pointing and clicking at various menus. Windows® or Mac® users will feel quite at home.
281 The best reference for **KDE** is the on-line documentation. **KDE** comes with its own web browser, **Konqueror** , dozens of useful applications, and extensive documentation. The remainder of this section discusses the technical items that are difficult to learn by random exploration.
283 #### The KDE Display Manager
285 An administrator of a multi-user system may wish to have a graphical login screen to welcome users. [ XDM](x-xdm.html) can be used, as described earlier. However, **KDE** includes an alternative, **kdm** , which is designed to look more attractive and include more login-time options. In particular, users can easily choose (via a menu) which desktop environment ( **KDE** , **GNOME** , or something else) to run after logging on.
287 To enable **kdm** , the `ttyv8` entry in `/etc/ttys` has to be adapted. The line should look as follows:
290 ttyv8 "/usr/local/bin/kdm -nodaemon" xterm on secure
298 [**Xfce**](http://www.xfce.org/) is a desktop environment based on the GTK+ toolkit used by **GNOME**, but is much more lightweight and meant for those who want a simple, efficient desktop which is nevertheless easy to use and configure. Visually, it looks very much like **CDE**, found on commercial UNIX systems. Some of **Xfce**'s features are:
300 * A simple, easy-to-handle desktop
302 * Fully configurable via mouse, with drag and drop, etc
304 * Main panel similar to **CDE**, with menus, applets and applications launchers
306 * Integrated window manager, file manager, sound manager, **GNOME** compliance module, and other things
308 * Themeable (since it uses GTK+)
310 * Fast, light and efficient: ideal for older/slower machines or machines with memory limitations
312 More information on **Xfce** can be found on the [Xfce website](http://www.xfce.org/).
316 A binary package for **Xfce** exists. To install, simply type:
320 This should install the main xfce4 desktop package, and most of the required components.
322 Alternatively, to build from source, use dports:
325 # cd /usr/dports/x11-wm/xfce4/
329 Now, tell the X server to launch **Xfce** the next time X is started. Simply type this:
331 % echo "/usr/local/bin/startxfce4" > ~/.xinitrc
333 The next time X is started, **Xfce** will be the desktop. As before, if a display manager like **XDM** is being used, create an `.xsession`, as described in the section on [ GNOME](x11-wm.html#X11-WM-GNOME), but with the `/usr/local/bin/startxfce4` command; or, configure the display manager to allow choosing a desktop at login time, as explained in the section on [ kdm](x11-wm.html#X11-WM-KDE-KDM).
336 <!-- XXX: FreeBSD's handbook has a nice user-oriented section about X applications here. maybe we should have one, too -->
