Troubleshoot Installation Wizard Display Issues

The STA installer verifies that X11 is properly configured for the Oracle user. If these prerequisite checks fail, contact your Linux system administrator for assistance.

You can use the following steps to help troubleshoot display problems.

1. Log in to the STA server as the Oracle user, and display the currently installed RPM packages.

   $ yum list installed
   

   The xorg-x11-util entry should be included in the displayed list. For example:

   xorg-x11-utils.x86_64                  7.5-6.el6 
   

2. Display the current display settings. For example: $ echo $DISPLAY

3. Verify the display has the proper X11 configuration. For example:

   $ xdpyinfo –display :0.0
   

   Example showing properly configured X11:

   $ xdpyinfo
   name of display:    :0.0
   version number:    11.0
   vendor string:    The X.Org Foundation
   vendor release number:    11300000
   X.Org version: 1.13.0
   maximum request size:  16777212 bytes
   motion buffer size:  256
   

   Example showing improperly configured X11.

   $ xdpyinfo
   xdpyinfo:  unable to open display ":0.0".
   
   $ xdpyinfo
   PuTTY X11 proxy: MIT-MAGIC-COOKIE-1 data did not matchxdpyinfo:  unable to open display ":0.0".
