I did the installation with the external lcd 19" connected to the vga.
At first boot both the displays were not able to show the "Next" buttons...
But I didn't try to auto-adjust the external one (and on the laptop I
presume it is impossible... correct?)
During install Xorg chooses a mirror (or clone .. donna if they are
the same thing) config and probably the fact that one is 4/3 and the
other is 16/9 bring problems inside....
X.log I saved during install in fact contains :

So that virtual size seems strange...
I can send it entirely if it may help. this virtual size is the same
during first boot

Eventually I can try to do same install in these conditions and check results:
1) external monitor disconnected
2) external monitor connected, both at install phase and first reboot
phase, and auto adjust on it after first reboot
