Comment 67 for bug 753971

Same behavior as described in #66.

Besides I could not set primary display via the Monitor Preferences. I tried to order the monitors in every way but unity dock is staying on the the laptop lcd.
In some configuration the external monitor is having corrupted screen - color is invalid or monitor show a message resolution is not supported but the resolution and refresh rate are set properly

And even if my laptop lcd - LVDS1 - is closed - during startup or closing later - X is always starting on the internal lcd. I see that xrandr can see LVSD1 as connected even if the display is closed.

With xrand commands the config can be correct.
I can execute the following in my case and then everything is fine:
#########################################################
#!/bin/bash

off=$(xrandr|grep "\ connected"|grep LVDS1|head -1|awk '{print $1}')
output=$(xrandr|grep "\ connected"|grep -v LVDS1|head -1|awk '{print $1}')
if [ -n "$output" ]
then
 xrandr --output $output --primary
 if [ -n "$off" ]
 then
  xrandr --output $off --off
 fi
fi
