I think I already know what you are going to say:
The resolution in this xorg.conf file is wrong.
In the Screen section it says:
Modes "1024x768"
instead of
Modes "1680x1050"
As I'm not a xorg specialist, I just changed that line and tested. Same Problem.
I have to say, my laptop display is broken so I can't tell you what happens there.
But I would guess, that it is set up perfectly correct.
So the whole problem seams to be a wrong xorg.conf configuration when booting from LiveCD.
here is the xorg.conf
