I have just upgraded my Fedora 20 box to Plasma 5. I have two problems.
1. I can't use SDDM. System shows booting Fedora 20 - kernel version.
It never reaches desktop. KDM works fine.
2. Time to time I book into black background empty desktop. There is
nothing on the desktop. No panel, etc. I can still use all the
applications using KRunne and window switching Atl-Tab.
Any idea how can I resolve these issues especially the second one.
