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 ######################################################### SW: ii unity 3.8.16-0ubuntu1~natty1 Interface designed for efficiency of space and interaction.
