It's really great: I have managed to boot the graphic mode with xfce4 with success for the first time, however, the keyboard and mouse usb, that in text mode are perfect, both collapse on graphic mode. Their leds show they are connected to the system but none of them function.
below is the output of #lsusb and the pastebin of xorg.0.log with some information about the keyboard and the mouse usb
