Troubleshooting
Problem
On UNIX platforms, you may see blank boxes displayed inside the graphical Configuration Manager CMUI after you launch configmgr using an XWin server.
Cause
This behavior is usually caused by either incorrect permissions on the required third-party display libraries, or missing entries in the Pango modules cache list.
Environment
UNIX
Diagnosing The Problem
Launching gtk-demo results in the utility displaying boxes where there should be characters, and Pango "bad font" errors.

Resolving The Problem
1. Verify that the user you use to launch configmgr has read access to the directory, subdirectories, and files where you installed the shared libraries, which defaults to:
/opt/freeware
2. (a) Check the contents of the /opt/freeware/etc/pango/pango.modules file. This file should list all of the modules installed at /opt/freeware/lib/pango/1.5.0/modules.
This problem will occur if there is only one line in the pango.modules file, as shown:
/opt/freeware/etc/pango> cat pango.modules
# Pango Modules file
# Automatically generated file, do not edit
#
# ModulesPath = /opt/freeware/lib/pango/1.5.0/modules
#
/opt/freeware/lib/pango/1.5.0/modules/pango-basic-x.la BasicScriptEngineX PangoEngineShape PangoRenderX common:
(b) If this file does not list all of the installed Pango modules, adjust it by running the following command:
/opt/freeware/bin> ./pango-querymodules > '/opt/freeware/etc/pango/pango.modules'
(c) Verify that the pango.modules file contains references to all pango-<lang> modules installed:
/opt/freeware/etc/pango> cat pango.modules
# Pango Modules file
# Automatically generated file, do not edit
#
# ModulesPath = /opt/freeware/lib/pango/1.5.0/modules
#

3. Verify that you have installed all of the required X11 filesets on your AIX server. See this WebSphere TechNote for additional information:
http://www-01.ibm.com/support/docview.wss?uid=swg21641125
4. Launch gtk-demo, and verify that the characters are now correctly displayed:
