Lets you specify which user interface “Look and Feel” to use. This switch is currently only available on Linux. Currently only gtk is supported. This starts the GroupWise Cross-Platform client on Linux using the GTK “Look and Feel”. This only works properly if you are using the GNOME* desktop manager.
Syntax: -ui=xxx
Example: /opt/novell/groupwise/client/bin/groupwise.sh -ui=gtk
this startup switch is not available in the Windows client or the Macintosh Cross-Platform client.
