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...

Marking this resolved since the other bugs I linked to are fixed. I ended up turning the radeon card off permanently anyway for power reasons and just used intel.
