This has the benefit of dynamically enabling or disabling additional heads. The configuration is slightly different, here is a pertinent snippet from mine for comparison. There is only one device, screen and monitor specified in the conf.=20 Section "Device" Identifier "Card0" Driver "intel" VendorName "Intel Corporation" Option "DRI" "true" BoardName "Mobile Integrated Graphics Controller" BusID "PCI:0:2:0" Screen 0 EndSection Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" SubSection "Display" Viewport 0 0 Depth 32 Modes "1400x1050" Virtual 2680 1050 EndSubSection EndSection My laptop has an internal 1400x1050 screen, and also a 1280x1024 external screen to its left. It's enabled from my .xinitrc with a command like 'xrandr --output VGA --mode 1280x1024 --left-of LVDS'. Apparently due to hardware limitations, if your 'Virtual' is more than 2048x2048 in any dimension, then DRI won't work.
