Why doesn the graphical installation tool start when it is executed as root on a UNIX system?
On many UNIX systems the DISPLAY environment variable is unset for the root user. Enter “echo $DISPLAY” to determine if the environment variable has been specified. If this command returns “:0.0” or “unix:0” as the variable value, the variable is set to the current working node. If the command does not return a string, the variable is unset. Enter “setenv DISPLAY hostname:0.0” in a C Shell to set the variable.
