How to change the new workspace icon to the older icon?

The new "Workspace" icon is very similar the "Terminal" icon and I prefer the older icon. How can I change it?

P.S.: Sorry for my English ;-)

Solution 1:

In a gnome-terminal do:

• Backup the old icon:

  sudo mv /usr/share/icons/unity-icon-theme/apps/48/workspace-switcher.png{,.bak}
  

• Convert the old icon from SVG to PNG and place it in the correct directory (this needs the convert program from the imagemagick package, which is not installed by default):

  sudo convert -background None /usr/share/icons/Humanity/apps/48/gnome-panel-workspace-switcher.svg /usr/share/icons/unity-icon-theme/apps/48/workspace-switcher.png
  

• Update the theme's icon cache:

  sudo update-icon-caches /usr/share/icons/unity-icon-theme
  

• Restart unity

  (unity &)
  

The downside: whenever the icon theme gets updated, you'd need to repeat that process.

Enjoy!
