I've got a Sun Ultra 5, a Sun Blade 150 and a Sun Ultra 2. The Ultra 5 and the Blade 150 are running Solaris 10. The Ultra 2 is running Solaris 9. I'd like to configure as many of them as possible to run the KDE desktop. I've noticed that, on the systems running Solaris 10, there's a directory named /opt/sfw/kde. However, KDE is not among the session options available on the login screen.
