Graphical Environment configuration files

Graphical Environment Guide
Chapter 1, Overview of the Graphical Environment

The major components of the Graphical Environment have their own configuration files. These files can be modified to implement the customizations to the Graphical Environment that you desire.

There are at least two versions of each of these configuration files on the system: one that resides in the user's $HOME directory and affects only that user, and one that provides default specifications for the entire system. Table 1-1, ``Files used to customize the Graphical Environment'' summarizes the configuration files that are used by the Graphical Environment.

 Window manager: 
 /usr/lib/X11/system.pmwmrc                           $HOME/.pmwmrc
 /usr/lib/X11/system.mwmrc                            $HOME/.mwmrc
 Desktop: 
 /usr/lib/X11/IXI/XDesktop/rules/system/xdtsysinfo    $HOME/.xdtuserinfo
 /usr/lib/X11/IXI/XDesktop/rules/modules/module       $HOME/.xdt_dir/modules/module 
 /usr/lib/X11/IXI/XDesktop/rules/SCO.user/Main.dt     $HOME/Main.dt
 /usr/lib/X11/IXI/XDesktop/rules/SCO.user/ll_TT.prf   $HOME/.xdt_dir/installed.prf
 /usr/lib/X11/IXI/XDesktop/rules/SCO.user/Rule.dr
 directory/.xdtdir/ll_TT                              $HOME/directory/.xdtdir/ll_TT

Note the following:

client is the class name of the X client to which the resource specifications in the file apply
hostname is the name of the system on which the client is running
module is the name of the module file, and can include ``auto'' modules, with the .auto suffix, and ``loop'' modules, prefixed with Loop_
ll_TT represents language and locale, where ll is a two-character code for the language (as defined by the ISO 639 standard) and TT is a two-character code for the territory (as defined by the ISO 3166 standard). By default, ``en_US'' is used.
directory is the name of the directory in which the rule file exists.
the desktop defines the $XDTHOME environment variable to be /usr/lib/X11/IXI/XDesktop and the $XDTUSERHOME environment variable to be $HOME/.xdt_dir. You can use these variables to aid in locating the desktop files listed in this table.
