LXDE is by design a light-weight graphical environment with no direct composite manager.
Lubuntu does have the X composite extensions built in though with allows you to install a composite manager of your choice, for example
- xcompmgr - a basic lightweight composite manager with a few effects such as shadows and translucent windows. Works with Cairo or Docky. N.B. don't forget to add xcompmgr as part of your autostart programs on logon.
- metacity - the standard software based composite manager for basic graphics cards
- compiz - the fully fledged all singing all dancing wobbly effects composite manager requiring a more modern graphics card.
Cairo with xcompmgr in Lubuntu:
From ubuntu community help:
Compiz and Cairo are two rather heavyweight solutions with lots of
resource-heavy eyecandy. An alternative consistent with the small
footprint of Lubuntu is xcompmgr.
sudo apt-get install xcompmgr
gksudo leafpad ~/.config/lxsession/Lubuntu/autostart
