3. Buat Skrip wrapper untuk memanggil conky

sepertinya conky tidak akur dengan compiz jika dijalankan di awal, Jadi kita buat script berikut untuk memanggil conky 20 detik setelah compiz berjalan (atau sesuaikan dengan kondisi anda).

#!/bin/bash

sleep 20 && conky -d

letakkan di home folder misalnya dengan nama conky-start.sh , ubah mode nya menjadi executable,

chmod +x conky-start.sh

dan masukkan di startup session gnome.
buka System – Preferences – Startup Applications, dan tambahkan entry untuk conky, pada kolom command silahkan browse ke file yang kita buat tadi.

Selanjutnya kita conky akan langsung dijalankan pada waktu kita login ke desktop kita, atau untuk menjalankan manual kita bisa buka jendela run (Alt+F2) dan ketikkan conky -d

UPDATE : 31 Oct 2011

Untuk menampilkan di gnome-shell ganti pada bagian pada bagian # spesifikasi window # menjadi seperti berikut:

own_window yes
own_window_transparent yes
#own_window_type override

own_window_class Conky
own_window_type conky

own_window_hints undecorated,below,sticky,skip_taskbar,skip_pager
