I also lost most of my xfce desktop. Very frustrating, must be a recent upgrade that borked something.
However,
as my sig displays, my efforts to find a solution were very unsuccessful. Very. I now have no windowing/X system in my gdm, just 3d config and "run an X script"
So,
Is there a way to install task-xfce from cli?
If i use rpm I would need a full list of all files, and tell me if I'm wrong, some way to identify the files on the cd? or through a repo? rpm won't calculate my deps right?
