enabling docky effects in xfce

By default, Docky should work with the built-in XFCE/Xubuntu compositor.

In 12.04 the compositor can be checked (if it is not already) via the window-manager tweaks

The image above shows Docky does not have the 3D effects, but by checking the options you'll have the 3D effects as per the next image:

If, for whatever reason the inbuilt compositor does not work for you, you'll need another compositor to help out Docky.

alternative method for both XFCE/LXDE

A good lightweight compositor is xcompmgr

xcompmgr Install xcompmgr

enter image description here

As the image above shows, the inbuilt compositor is not running. xcompmgr is running, which gives Docky the 3D effects you require.

Use session and startup to run xcompmgr when you login.
