My computer is connected up to a monitor (by VGA) and a HD TV by HDMI. It's using integrated graphics on my motherboard (Gigbyte Z68X-UD3H-B3). It works fine in Windows 7 and GRUB will display on both monitors during start up but I can only get Ubuntu to display on the VGA monitor.
Heres the output of xrandr:

Any one got any ideas?
