How to fix huge FS Icons in Ubuntu 15.04 menubars?

Solution 1:

Apparently, scalable icons are used in the menubars for Ubuntu 15.04. The FS Icon set specifies a minimum value for the scalable icons as 257 pixels. The solution is to set the minimum value appropriately, so the icons can be scaled down to the required size.

sudo sed -i "s|MinSize=|MinSize=8\n#MinSize=|g" /usr/share/icons/fs-icons-ubuntu*/index.theme
