Store Permanently Ubuntu Multiple Displays Setting

In Ubuntu 12.04 and maybe others, if we set displays for multiple monitor it just works for the current session. It means, if we restart our PC, the setting was gone and we need to set up again via display setting as shown from the picture below.

To store permanently the multiple monitors setting in Ubuntu, we can manually set the xrandr by making file .xprofile in home directory (~/.xprofile). For example, to set extra monitor in the left side of main monitor permanently (as shown by the picture above), type the following in ~/.xprofile

xrandr –output VGA1 –left-of LVDS1
For complete instruction, you can follow the Ubuntu wiki here. The ~/.xprofile will be executed by xrandr every single start of Ubuntu. The example script above will locate the extra monitor to the left of main monitor, here are the sreenshot of mine.
