Since every single time I start Mathematica, my first action is aligning the windows properly (Notebook on the left for $2/3$ of the screen, help on the right for the other $1/3$), I was wondering whether this could be done automatically. This is what it looks like:

How could I make Mathematica to use these window positions and sizes by default?

On Windows I use "Tile Windows Tall" from the Window menu. I don't know if it's available on Linux. –  Szabolcs Feb 11 '12 at 23:18
You can do this by setting (SetOptions) the WindowSize option on all Notebooks[] but the documentation one for window size, WindowMargins for window positions. Get the usable screen size (sans Gnome panel) with ScreenRectangle /. Options[$FrontEnd, ScreenRectangle]. Sorry, no time for a proper answer, but you should be able to work out the details going from here. –  Szabolcs Feb 11 '12 at 23:29
I cannot seem to position the "Documentation Center" even if I directly edit System/Guides/Mathematica.nb so it seems the position of that is controlled elsewhere. –  Mr.Wizard Feb 11 '12 at 23:53

The help window position can be set to be remembered from the Options Inspector: open it, select Global preferences, go to Global Options -> Dialog Settings -> Help Viewer Settings and set Enabled to True.

Confirmed to work. It does not work after positioning only the Documentation Center page, but after position another window, that one also comes up in the new location. –  Mr.Wizard Feb 12 '12 at 4:03
Thank you, that's very helpful already. All that's left is now doing this for a new notebook as well. Would there be some way of having some autorun commands for each new nb created? –  David Feb 12 '12 at 6:46
Unfortunately it is not possible to set a global default size and position for each new notebook that is created. So the 1/3 screen for the help browser is possible but not the 2/3 screen for the notebook. –  Mike Honeychurch Feb 12 '12 at 11:44
@David I don't know. I tried to change things like DefaultNotebook in the past but could not get it to work. I would very much like to know, too, for the same reason as you. –  acl Feb 12 '12 at 13:38
@acl I actually asked Tech Support about this a week or so ago after I couldn't figure out how to answer a question re: default size and positioning of notebooks. They advised it is not possible to globally set default size and position for new notebooks. (whereas you can for various dialogs as above) –  Mike Honeychurch Feb 12 '12 at 23:59
