If you do, this post is for you!
How do you get one? First this show desktop button ONLY works with compiz (for now at least). Here goes the instructions:
1 – Activate desktop effects aka compiz
2 – Activate the dbus plugin
2 – Download my show_desktop.py python script, save it somewhere safe and make executable.
3 – Create a menu entry for the script in GNOME’s main menu and assign a nice desktop icon from a theme of your choise
4 -Add the menu entry to your docky.
5 – Enjoy your new “show desktop” botton!
Here goes the absolutely necessary screenshot
