I installed indicator-cpufreq but it doesn't work with the Faenza icon theme. Is there a way to make the indicator use the icon from the ubuntu-mono-dark icon theme?
Goto the installed icon folder (.icon in home folder if you installed for current user)
Open index.theme file in gedit or any text editor.
In inherit field put the backup icon theme name at front.
An example
Inherits=ubuntu-mono-dark,gnome,hicolor
So the line means, if no icon found in this icon-theme, search in ubuntu-mono-dark, if not available in ubuntu-mono-dark searach icon in gnome, if not available in gnome set take from hicolor
