How to setup a conky in Trisquel-mini 6.0 64 bit?

How are you making conky start when after you login?

Problem solved.

LXDE is by design a light-weight graphical environment with no direct composite manager.
There are 3 options:

1. 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.
2. metacity - the standard software based composite manager for basic graphics cards
3.compiz - the fully fledged all singing all dancing wobbly effects composite manager requiring a more modern graphics card.

I installed first manager and now I have transparency.

sudo apt-get install xcompmgr

After this must to go in: /etc/xdg/lxsession/Trisquel-mini
and edit the file "autostart" and add:

@conky -p 3
@xcompmgr -c

My autostart file have this:

@lxpanel --profile Trisquel-mini
@xscreensaver -no-splash
@xcompmgr -c
@gnome-power-manager
@pcmanfm --desktop --profile Trisquel-mini
@/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1
@conky -p 3

I found the answer here: http://askubuntu.com/questions/53745/compositing-in-lubuntu

"There are 3 options"

There is a fourth, and it is the better option out of all four. Use Compton.

Here are some directions for installing on XFCE wich work just fine in LXDE as well. http://www.neowin.net/forum/topic/1148464-using-compton-for-tear-free-compositing-in-xfce/
