I didn’t install xfce when I was installing Tumbleweed, but I would like to add it now. The problem I’m having is that when I try:
sudo zypper install xfce4
I get back something to the effect that the system is unable to locate a provider of xfce4. I gather this could be because the package is under a name other than xfce4 or it could be because I need to add a repository.
