On some minimal systems where the LIVE Server is installed (usually a gateway system), the rgb file may be missing. This file associates the standard color names with their corresponding color codes. Without this file, applications may fail or throw error messages stating that the color is not defined.
These messages will not appear on non LIVE connetions as X-Win32 ships with its own rgb map.
To resolve this issue,
- Download the rgb.txt file onto your remote system
- Place the rgb.txt file in /etc/X11/
- Restart the LIVE Server
