Setting X Resources
The Graphical User Interface is an X Window System application which means it
is a client in the X Window System client-server model.
The X server is a program that controls all access to input devices (typically a
mouse and a keyboard) and all output devices (typically a display screen). It is an
interface between application programs you run on your system and the system
input and output devices.
An X resource controls an element of appearance or behavior in an X application.
For example, in the graphical interface, one resource controls the text in action key
pushbuttons as well as the action performed when the pushbutton is clicked.
By modifying resource settings, you can change the appearance or behavior of
certain elements in the graphical interface.
When the graphical interface starts up, it reads resource specifications from a set of
configuration files. Resources specifications in later files override those in earlier
files. Files are read in the following order:
278
1 The application defaults file. For example,
/usr/lib/X11/app-defaults/HP64_Softkey in HP-UX or
/usr/openwin/lib/X11/app-defaults/HP64_Softkey in SunOS.
2 The $XAPPLRESDIR/HP64_Softkey file. (The XAPPLRESDIR environment
variable defines a directory containing system-wide custom application
defaults.)
3 The server's RESOURCE_MANAGER property. (The xrdb command loads
user-defined resource specifications into the RESOURCE_MANAGER
property.)
If no RESOURCE_MANAGER property exists, user defined resource settings
are read from the $HOME/.Xdefaults file.
4 The file named by the XENVIRONMENT environment variable.
If the XENVIRONMENT variable is not set, the $HOME/.Xdefaults-host file
(typically containing resource specifications for a specific remote host) is read.
5 Resource specifications included in the command line with the -xrm option.
