I have just migrated to Ubuntu and tweaked the Unity Desktop environment to my heart's content. I wanted a nice flat material design theme for my desktop. Everything went well but the launcher_bfb button didn't change. It still had a shadow and a glow. After googling I found out that the icon is placed in the following directory: /usr/share/unity/icons
.
The launcher_bfb icon is made up 13 different png and svg images (atleast in Ubuntu 16.04), namely,
- launcher_bfb.png
- launcher_icon_back_54.svg
- launcher_icon_back_150.svg
- launcher_icon_edge_54.svg
- launcher_icon_edge_150.svg
- launcher_icon_glow_62.svg
- launcher_icon_glow_62.png
- launcher_icon_glow_200.svg
- launcher_icon_selected_back_54.svg
- launcher_icon_selected_back_150.svg
- launcher_icon_shadow_62.svg
- launcher_icon_shadow_200.svg
- launcher_icon_shine_54.svg
I just replaced these files (except the first one) with blank png/svg files of same dimensions and it worked for me.
