Hello Malcolm, thank you for your reply. I listed the parameters and values but I do not find anything that may help me start a second VNC session.
I am able to this on RedHat Enterprise and on other levels of Suse Enterprise. With other versions of Suse I can go into Applications -> System Tools -> Settings -> Sharing and turn on Screen Sharing and Remote Login. Where are these parameters and values stored? What can I do to gather diagnostics to determine what the problem? What the parameter values are? Where and how to change them?
