I have additional information. Earlier in this report I posted ati.png which showed my dual screen configuration (at work). I am currently at home. I looked at it and saw that it seems, that at bootup my system detected that it only has 1 (the built in display) connected. So from the systems point of view, there is only one display. see the new attached image. thunderbird still not starting when using main display.
