I am running openSUSE Tumbleweed and would like to use xfce as my desktop environment. GNOME works flawlessly, but I am having a big problem with xfce.
The problem is that xfce crashes on the launch of certain applications such as Firefox, Dragon Player, and others. When I attempt to launch one of these applications, I get a blank black window and xfce freezes. I can only get out using ctrl-alt-backsp. The strange thing is that after I execute that key combination, I momentarily see the desktop as it really should be, e.g. Firefox with my home page displayed and then I'm out.
This doesn't happen with all applications. I can still load the various settings without problems, Chromium browser works, the terminal works, and so does the file browser. I am sure there are others that work too.
Any ideas would be greatly appreciated. Thank you.
