Based on the xrandr output you posted, it looks like your card or driver does not support the DVI output. Try using one of the other outputs, and make a simple xrandr script to configure your monitors at login.

My login script is just one line like this:

xrandr --output VGA-0 --left-of DVI-0 --primary

I called it lxde-setup.sh and added it to the startup actions.
