Diagnostics
A wide variety of error messages are generated from various programs. The default error handler in Xlib
(also used by many toolkits) uses standard resources to construct diagnostic messages when errors
occur. The defaults for these messages are usually stored in /usr/lib/X11/XErrorDB. If this file is not
present, error messages will be rather terse and cryptic.
When the X Toolkit Intrinsics encounter errors converting resource strings to the appropriate internal
format, no error messages are usually printed. This is convenient when it is desirable to have one set of
resources across a variety of displays (e.g. color vs. monochrome, lots of fonts vs. very few, etc.),
although it can pose problems for trying to determine why an application might be failing. This behavior
can be overridden by the setting the StringConversionsWarning resource.
To force the X Toolkit Intrinsics to always print string conversion error messages, the following
resource should be placed in the .Xdefaults file in the user's home directory. This file is then loaded into
the RESOURCE_MANAGER property using the xrdb program:
*StringConversionWarnings: on
To have conversion messages printed for just a particular application, the appropriate instance name can
be placed before the asterisk:
xterm*StringConversionWarnings: on
