Just for your information:
after applying the cr-updates to a C6.5 my screens on my laptop renamed from VGA1 and eDP1 to VGA-0 and eDP-0.
And since X insists that my VGA is left to my eDP (and my scripted xrandr was confused by the renaming) I had to go to the left to reach my right screen. I needed some more coffee this morning.
