Thank you for taking the time to report this bug and helping to make Ubuntu better. Please attach your X server configuration file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.0.log) to the bug report as individual uncompressed file attachments using the "Attachment:" box below. Could you please also try to run without any /etc/X11/xorg.conf and let Xorg autodetect your display and video card? Please also attach the /var/log/Xorg.0.log from this attempt. Thanks in advance.
Please also attach the output from "xrandr".
Most probably the driver is seeing a second "ghost" screen that is using as primary, cloning the image to the secondary (and only real) screen. Try disabling the second output with "xrandr --output XXX --off"
