Using vgaswitcheroo to switch between intel and radeon. When radeon is selected
I get a black screen after boot (when KDE has started). Only when connecting an
external monitor the LCD display gets turned on. I can then disconnect and
connect an external monitor without any problems, but the only way to get the
LCD turned on initially is by connecting an external monitor. This workaround
is ok at home and at work, but not while travelling...
