(:6465): Gtk-WARNING **: cannot open display:
Reason
This error occurs because the installer is using the default JVM that is installed on the machine. Many times this is a 1.2.x version of the JVM. ColdFusion MX 7 requires at least the 1.4.2_05 or higher JVM, but is not supported on 1.5._XX JVMs.
Solution
To work around the problem, use the command line parameter LAX_VM to specify the Java executable file to use during the installation. The following example uses the updater2 installer:
./coldfusion-70-updater2-lin.bin LAX_VM /$JAVA_HOME/bin/java
