I performed a Minimal X install (IceWM) of openSUSE 13.2. I installed Enlightenment 19 from the enlightenment package in YaST. I also installed gnomesu. However, when I'm using Enlightenment 19 and I run gnomesu yast2 from the command line, a dialog opens and prompts me for my password. After I enter the password and click Continue, the dialog closes and yast2 does not open. It works fine in IceWM, however.
