A small GUI exists for doing this: Arandr. You can install it from Synaptic. If it doesn't work, try Grandr. Arandr will save the setting in a hidden folder .screenlayout. You will have to add the .sh to startup. See http://douwil7.100webspace.net/linux/Tuning.html#16 for additional information.

Grandr works fine,
but when I restart the session, It lost the configurations.

how can I save my configurations changes in Grandr?
