I just installed my-humanity icon theme on my Ubuntu 12.10 but i have an issue :
I extracted the archive to /usr/share/icons or/and to ~/.icons but when i apply the icon theme from gnome twek tool home folders icons dont update but stay to Ubuntu mono dark default icons. Only Launcher/tray icons change
I attach screenshots in order to understand whats my issue :
My folder icons on home :
How they should be : 
Any ideas on how can i fix it ? Note : On nautilus as root (gksudo nautilus) they appear how they should be .. Only on user do not appear !
sudo? because then you would have applied the changes only to the root account. – fotomonster Dec 2 '12 at 8:44
