Move window buttons back to the right in Ubuntu 10.04 / 10.10

One of the more controversial changes in the Ubuntu 10.04 beta is the Mac OS-inspired change to have window buttons on the left side. We’ll show you how to move the buttons back to the right.

How to move the window buttons
Press Alt+F2 to bring up the Run Application dialog box, enter “gconf-editor” in the text field, and click on Run.

The Configuration Editor should pop up.

The key that we want to edit is in apps/metacity/general.

The button layout can be changed by changing the “button_layout” key. Double-click button_layout to edit it.
Change the text in the Value text field to:  menu:maximize,minimize,close

Click OK and the change will occur immediately, changing the location of the window buttons in the Configuration Editor.

Done!Hope this help :)
