Thanks Matthias & Pedro, Yes, this was the initial point. I needed to connect the monitor through a DVI port and not through the display port.
Now all the system are recognized, but I am still stuck and it seems to be the composite extension of the desktop manager I am using lightdm and I tried to disable composite. But when I disable composite in xorg.conf I got the initial login screen but when I input the password I go back to the initial login screen back. I read that I should use MATE desktop, but I am unable to install it. I am not too familiar with Linux. Can you give me any hint of how to change the desktop manager. I think this is all I need, for the rest the card and the glasses seems to be working fine. Thanks in advance.
