[WS10.x] LightDM resolution problem

Hi

I installed Lubuntu 13.10 32-bit on a virtual machine of Workstation 10.x for Windows and I insert, in the /etc/lightdm/lightdm.conf file, the display-setup-script=/usr/bin/vmware-user statement which also allows resize the LightDM display but this statement causes its distorted view:

How come?

Thanks

Bye
