Progress bar icons for adjusting brightness and volume

Question

linux

Installed ubuntu 12.04 for the first time, additionally installed Gnome Shell, Kubuntu, xfce desktop environments. After that, the icons of the progress bars of brightness and volume changed in unity. Maybe someone knows how to return the default unity icons? Installed ubuntu-tweak, there it rolled back to the default icon theme ubuntu-mono-dark, all the icons returned, except for the icons for the progress bars of brightness and volume. Their location has also changed, before the progress bars popped up at the top right, now they are at the bottom center.
