Sorry, some manual work needed to run the server
* Log into the computer running HDA, e.g. as a normal user
* Edit the file /etc/sysconfig/vncservers (with your favorite text editor) Set the lines starting with VNCSERVER to read (remove the # at the start of the line) <small> VNCSERVERS="1:''yourusername''" VNCSERVERARGS[1]="-geometry 1024x768 -depth 16" </small>
where ''yourusername'' is the desktop user you use to access your HDA desktop.
