Hello

I'm still setting up my Ubuntu 12.04 (Precise Pangolin). Let's change the menu buttons (minimize, maximize, close) position to the right (again).

Open your Terminal
$ sudo apt-get install gconf-editor

Run it
$ gconf-editor

Go to "apps/metacity/general/"
Find "button_layout" and update the value to:

menu:minimize,maximize,close

Save, logout, login. Done!

Best Regards,
Matheus

PS: If you have any problem try to install "dconf-tools", open dconf-editor, close and then try to use this method again.
