Comment # 5 on bug 1187992 from andy great

I recently push update cinnamon-control-center 5.0.2 to X11:Cinnamon:Factory
which contain the file org.cinnamon.control-center.display.gschema.xml which
might solve this issue. The cinnamon-control-center version 5.0.0 does not have
this file because it did not exist, it seems to be add in a later version. I
still waiting for it to build and will submit to factory. From what I
understand X11:Cinnamon:Next is just a mirror of X11:Cinnamon:Factory, so
nothing new there.
