Enabling minimize and maximize buttons in gnome3 (Debian7)

In gnome3 by default only the close button is available at the right corner and the buttons for minimize and maximize that we are used to are missing. We can enable these buttons using the following steps

Click on the Activites tab on the top left corner. Then click on the Applications tab and choose Advanced Settings. A window as shown below will pop up.



Choose the option "shell" from the left column. Now look at the option labeled

"Arrangement of buttons on the titlebar"

A pull down menu lists the combinations in which the buttons can be displayed . To show all the buttons choose the option "All" and close the settings.



Now both minimize and maximize buttons should appear on the top right.
