If you are using -another distribution, or even another version of RedHat, or a different Workstation install, -then you may have to do some detective work. Hopefully, this info will give you what you need -to start detecting! This HOWTO began as the result of wondering how to add another window manager -or desktop environment to the drop-down list on the GUI login screen; further investigation -revealed other configuration options. - -I began my own "detective work" when I found a reference on a RedHat List which -mentioned <tt>/etc/inittab</tt>, and its role in system startup. In -<tt>/etc/inittab</tt> I found the following entries, which define how the -X Window System is started in my distribution and version: - -<tscreen><code> -# Run xdm in runlevel 5 -# xdm is now a separate service -x:5:respawn:/etc/X11/prefdm -nodaemon -</code></tscreen> - -Here is what prefdm looks like: - -<tscreen><code> -#!/bin/sh - -PATH=/sbin:/usr/sbin:/bin:/usr/bin:/usr/X11R6/bin - -# Run preferred X display manager -preferred= -if [ -f /etc/sysconfig/desktop ]; then - if grep -q GNOME /etc/sysconfig/desktop 2>/dev/null; then - preferred=gdm - elif grep -q KDE /etc/sysconfig/desktop 2> /dev/null; then - preferred=kdm - elif grep -q AnotherLevel /etc/sysconfig/desktop 2> /dev/null; then - preferred=xdm - fi -fi -if [ -z ":$preferred" ]; then - if which gdm >/dev/null 2>&1; then - preferred=gdm - elif which kdm >/dev/null 2>&1; then - preferred=kdm - elif which xdm >/dev/null 2>&1; then - preferred=xdm - fi -fi -if [ -n "$preferred" ] && which $preferred >/dev/null 2>&1; then - exec `which $preferred` $* -fi -exit 1 -</code></tscreen> - -No changes to prefdm are necessary; it determines which display manager is the -system default, and which runs the GUI login. During boot-up, prefdm parses -<tt>/etc/sysconfig/desktop</tt> and selects the display manager listed there; -in the case of my KDE Workstation install, this is kdm (KDE Display Manager). -Note that gdm (Gnome Display Manager) is not installed on my system; xdm (X -Display Manager) is installed by default as part of the X Window System, and -was apparently used by older versions of Red Hat. - -<!-- added caution and editing tips 2002/05/22 --> -<sect> Adding new window manager selections to the drop-down list -<p> -WARNING: The procedures explained in this HOWTO involve making changes to system -configuration files; if you are not experienced in making such changes, some -caution is required. Introducing errors into such files may make your system -unstable, or cause it to crash. The procedures explained in this HOWTO have -been tested and should not cause problems if used correctly. - -If you have KDE 2.2 or higher, and you are not comfortable with manual editing of system files, you may open a -terminal window (xterm or konsole) from your user desktop (NOT the root -desktop), then type and enter: - -<tscreen><code> -su -c 'kcontrol' -</code></tscreen> - -Enter your root password at the prompt, and make the changes from within the -KDE Control Center that appears: go to <em>Applications ==> Login Manager</em>. Choose -the appropriate configuration tab; you can easily configure every aspect of -the login screen from there. In Earlier versions of KDE, kcontrol can modify -kdmrc, but cannot modify Xsession which is used in those versions; see the -note below about changes from KDE 2.2 and higher. - -To see how to manually configure some of these, and see what these -configuration files do, proceed as follows: - -(Caution: Some configuration files have changed since the version of kdm -I'm using, particularly since KDE > 2.0: - -The following is quoted from -<url url="http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/x11-wm.html" name="the FreeBSD -Handbook-X11:"> - - "Note: -In KDE 2.2 this has changed: kdm now uses its own configuration files. Please -see the KDE 2.2 documentation for details.") - -<!-- add ref to kde 3.1 2003/04/13 --> - Note: -KDE 3.1 has added kdm documentation, see <url url="http://docs.kde.org/en/3.1/kdebase/kdm/" name="The kdm Handbook"> - -Much of the material in this new handbook applies to the older versions; -new features are also described therein. - -Check the documentation for your version to identify the current configuration -files if you want to manually edit these, or just want to see how they work. - - -Do <em>not</em> use a <em>word-processor</em> program for editing system configuration -files; such programs introduce special formatting characters which will corrupt the files. -Use a <em>text-editor</em>, particularly one which can handle long lines without introducing -extra carriage-return or line feed characters into existing code. Suitable editors include -vim (vi improved), vi, and emacs. There are others, but these are usually installed by default -in Linux workstation installations; they each have features which make them especially suitable for -writing and editing computer code. See the bibliography section at the end of this HOWTO for -more information. - -IMPORTANT: Before making changes to <em>any</em> system configuration files, you should make -back-up copies of the originals, so you can restore them in case of serious errors! - -The files which we will be changing here are <tt>/usr/share/config/kdmrc</tt>, which -is where we add selection labels to the drop-down list on the login screen, and -<tt>/etc/X11/xdm/Xsession</tt>, which is where we add the path to the executables -for our labels (if you are using a different distribution, the path to these -files may be different; just do "<tt>locate kdmrc</tt>" and "<tt>locate Xsession</tt>" -in the shell [i.e., in a terminal emulation, such as <em>xterm</em>, or KDE's <em>konsole</em>] -to find them). - -The default line to change in kdmrc looks like this: - -<tscreen><code> -SessionTypes=kde;gnome;anotherlevel;default;failsafe; -</code></tscreen> - -After adding selection labels for two new window managers, windowmaker and blackbox, the line looks like this: - -<tscreen><code> -SessionTypes=kde;gnome;windowmaker;blackbox;anotherlevel;default;failsafe; -</code></tscreen> -<!-- cleaned up phrasing in this paragraph 21May2002 --> -Notice the positions where I have added the labels for the new window managers; all -entries will appear on the drop-down list in the same order as they -appear in the SessionTypes list. Next, the actual choosing takes place in -<tt>/etc/X11/xdm/Xsession</tt>. Here is what the appropriate section of -Xsession looks like before adding the new entries: - -<tscreen><code> -# now, we see if xdm/gdm/kdm has asked for a specific environment -# -case $# in -1) - case $1 in - failsafe) - exec xterm -geometry 80x24-0-0 - ;; - gnome) - exec gnome-session - ;; - kde) - exec startkde - ;; - anotherlevel) - # we assume that switchdesk is installed. - exec /usr/share/apps/switchdesk/Xclients.anotherlevel - ;; - esac -esac -</code></tscreen> - -<!-- removed for clarity "I have just copied, pasted, and edited (to help avoid mis-typing) existing entries -to create the new entries." 21May2002 --> -<!-- added "appropriate section of the" 14Apr2002 --> -<!-- re-phrased "NOTE" to clarify; added "spelling and case..." 21May2002 --> - -Here is what this section of the Xsession file looks like after adding the new - entries (NOTE that the selection labels <em>must</em> be <em>exactly</em> the -same in Xsession and prefdm, i.e., spelling and case must be identical): - -<tscreen><code> -# now, we see if xdm/gdm/kdm has asked for a specific environment -# -case $# in -1) - case $1 in - failsafe) - exec xterm -geometry 80x24-0-0 - ;; - gnome) - exec gnome-session - ;; - kde) - exec startkde - ;; - windowmaker) - exec wmaker - ;; - blackbox) - exec blackbox - ;; - anotherlevel) - # we assume that switchdesk is installed. - exec /usr/share/apps/switchdesk/Xclients.anotherlevel - ;; - esac -esac -</code></tscreen> -<!-- added path note 2002/05/22 --> -Note that when the executables are installed in one of the paths shown below, only the -executable name is required after "exec"; otherwise the full path must be included, -as shown for "Xclients.anotherlevel" (above): - -<tt>/usr/bin/</tt> - -<tt>/usr/local/bin/</tt> - -<tt>/usr/X11R6/bin/</tt> - -<tt>/usr/bin/X11/</tt> - -These examples should be enough for you to add your favorite window manager(s) to the -KDE graphical login, or to give you a starting point to find out how it's done in your -particular installation. - -<!-- added two new sections 2002/05/22 --> -<sect>Enabling user selection icons in the login dialog box -<p> -In RedHat 6.1, the default KDE login window shows a dialog box with a space to -type in the user name, one in which to type the user password, and a drop down -list to select the window manager/desktop environment of choice. By making the -following changes to <tt>/usr/share/config/kdmrc</tt>, user icons will appear in -the top of the login box. -Here is what the default lines that control user icon view in kdmrc look like (other -lines between these two are not shown, and are represented by "..."): - -<tscreen><code> -#Users=root;johndoe -... -UserView=false -</code></tscreen> - -Here are the same lines after editing; delete the comment character ("#") in -front of "Users=..." and change "johndoe" to your username (if there are more -user accounts on your system, you may add their usernames here, separated by semi-colons -as shown). Change "UserView=false" to "UserView=true" as shown here: - -<tscreen><code> -Users=root;johnpipe -... -UserView=true -</code></tscreen> - -Now, when you login, you may click on an icon with the mouse to enter the user name; you must still type in your password. - -<!-- new info on adding your own icons --> -You can add your own icons in place of the default icons; place you own icons -in /usr/share/apps/kdm/pics/users/. They should be of size 64 x 64, according -to the kdm handbook; in KDE 1.x, the default icons are 62 x 63, and my new user icon is 60 -x 60, so if icons are reasonably close to the specified 64 x 64 size, they -will work OK. The handbook says "kdm is able to handle icons of different -sizes, but the result looks messy.", so there is evidently some leeway here. -Your icons should be named 'username.xpm', for example my username is -"johnpipe" and my new icon is named 'johnpipe.xpm' - -NOTE: at some time since kde 1.x, the icon format has been changed from '.xpm' -(XPixMap) to '.png' (portable network graphic). - -<sect>Requiring root permission for shutdown -<p> -The default for the shutdown button on the login box allows anyone to use it to shutdown the system. -The section in <tt>/usr/share/config/kdmrc</tt> controlling who may use this button looks like this: - -<tscreen><code> -#ShutdownButton=RootOnly -ShutdownButton=ConsoleOnly -</code></tscreen> - -To enable only the root user to shutdown the system, change the lines as shown below: - -<tscreen><code> -ShutdownButton=RootOnly -#ShutdownButton=ConsoleOnly -</code></tscreen> - -Clicking the shutdown button will now prompt for the root password before shutting down the -system. - -<sect>Bibliography -<p> - -For more HOWTO's, see <url url="http://www.tldp.org/" name="The Linux Documentation Project"> - -Recommended reading: - -<itemize> -<item><url url="http://www.tldp.org/HOWTO/XWindow-User-HOWTO/" name="XWindow-User-HOWTO"> -<item><url url="http://www.tldp.org/HOWTO/Emacs-Beginner-HOWTO.html" name="Emacs Beginner's HOWTO"> -<item><url url="http://www.tldp.org/HOWTO/Vim-HOWTO.html" name="Vim Color Editor HOW-TO (Vi Improved with syntax color highlighting)"> -</itemize> - -Depending on your Linux distribution and version, you may already have the -above HOWTO's installed on your system.
