Comment 6 for bug 541467

The interfaces tab should be in preferences - appearance in 9.10. That tab has been removed in 10.04.

You can use ubuntu-tweak ( A must have now that Gnome and Ubuntu love removing options) or:

Open your terminal and type in:

gconf-editor

In GConf-Editor, navigate to desktop -> gnome -> interface

There should be two checkboxes, one for buttons_have_icons and one for menus_have_icons,

enable those and close gconf-editor, but don’t close the terminal

Type in:

killall nautilus
