Modif script : lancer une commande supplémentaire

Bonjour à toutes et tous !
Je vous préviens directement, je n'ai aucune connaissance en programmation, mais ce que je cherche ne doit pas être bien compliqué si vous avez quelques bases.
Je cherche à modifier le script de wallpapoz, qui permet de changer le fond d'écran automatiquement à des intervalles de temps précis : je cherche également à relancer à chaque fois les desklets, car il y a un effet de rémanence sur leur fond : ils gardent en mémoire le fond d'écran précédent sans actualiser le nouveau.
Voici le script initial :

#!/usr/bin/env python
# -*- coding: utf-8 -*-

# This file will check desktop continously and change wallpaper

# this is index of wallpaper list of workspaces
# for example: number[0] is index of wallpaper list in first workspace
number = array.array('i')

## delay -- global variable, how many time will wallpaper list thread
#
# has to wait before it manipulate its index

# with calling external program

    ## class method to know what workspace we are in now

	desktop = os.popen('xprop -root _NET_CURRENT_DESKTOP').read()
	return int(desktop[33] + desktop[34])

    def change_wallpaper(self, wallpaper):
	os.system('gconftool-2 -t string -s /desktop/gnome/background/picture_filename ' + "\"" + wallpaper + "\"")

    system = System()

    # previous workspace
    previous_desktop = -1

    # previous wallpaper list index
    previous_index = -1

    # get the delay time and random preferences

    # create the thread

    for i in range(total_workspace):
	wallpaper_list.append(AsyncIndex(i))
	wallpaper_list[i].start()

    # the daemon that works forever
    while True:
	try:
	    # don't get rush
	    time.sleep(1)

	    # what workspace we are in now?
	    cur_desk = system.current_desktop()

	    # requirement for changing wallpaper
	    # 1. we change workspace
	    # 2. index of wallpaper list change
	    if previous_desktop != cur_desk or previous_index != number[cur_desk]:
		# if we move to workspace that we don't use, just ignore
		if cur_desk >= total_workspace:
		    continue

		# command to change wallpaper
		system.change_wallpaper(worklist[cur_desk][number[cur_desk]])

		# our previous workspace and index of wallpaper list
		previous_desktop = cur_desk
		previous_index = number[cur_desk]

	# ok, we stop this daemon
	except KeyboardInterrupt:
	    # now it's time for the main thread to exit
	    os._exit(0)

Je pense qu'il suffit simplement de lancer la commande "adesklets --nautilus" au bon moment pour faire ce que je cherche à obtenir... mais où ?

Merci de votre aide !

Re : Modif script : lancer une commande supplémentaire

Bonjour,

Essaie peut-être en dessous de ça.

 # command to change wallpaper
        system.change_wallpaper(worklist[cur_desk][number[cur_desk]])
        os.system("adesklet --nautilus")

C'est à tenter

Ben une mise à jour de wallpapoz fait que cette modification ne fonctionne plus... Je pige pas tout, j'essaie de voir ce que je peux faire en testant différentes méthodes mais pour le moment, ca ne marche pas...
