In Ubuntu 10.04 LTS ( Lucid Lynx ) the buttons in the window title bar ( maximize, minimize and close ) are moved to the left.
If you don’t like this you can easily change it back to the right.
- Install Ubuntu Tweak from : http://ubuntu-tweak.com/
- Run it and go to Window Manager settings
- Under window titlebar button layout, de-select custom and choose right.
