It is a second monitor (tv) that i need to watch movies.
So, if I connect the tv befor the boot it is identified from ARandR though with some resolution problem on both screens...
With the live session i could it connect after the boot and there were also less grafic problems.

That's the output with connected tv.
And when i maximize the browser window it takes the dimensions of the tv and not of the laptop.
And the tray is now brighter then the screens but this is not really a problem. Just wonder why it worked on the live session...
Edit
I could not reboot without tvhe connected tv. I had to kill the system with the off-botton, connect it again, boot, deactivate the tv from ARandR and reboot. Now is the grafic ok on the laptop.
