I have my Ubuntu Desktop (13.04) installation setup for dual monitors (one VGA and one HDMI, built-in display off) out of my laptop. This is working fine when I am logged in, however when I reboot the boot/login screen is only on my laptop screen. Since I want to have the laptop close and tucked away, this is a problem.
Any suggestions on how to get this to work properly? I tried a suggestion of adding a file to
/etc/X11/Xsession. I called it '98extmonitor' and it had the following contents:
xrandr -q | grep 'VGA1 connected' && xrandr --output LVDS1 --off --output VGA1 --auto
But that had no change in effect.
