xplanet sur Feisty

Bonjour,

Je m'essaie à faire marcher xplanet sur ma Feisty nouvellement installée, et pour l'instant c'est sans succès...

Voici les éléments...

Le script de téléchargement des nuages, download_clouds.pl est placé dans mon répertoire /home/jf/bin. Le voici :

use LWP::Simple;

# Set options:

# - how many times to retry, if the server doesn't respond

  if( IndicatesSuccess($Response)) {
    print "Finished: file successfully downloaded to $Filename\n";
    exit(0);
  }
  print "Download not available, trying another website\n\n";
}
print "ERROR: Tried to download the file $MaxRetries times, but no servers could provide the file\n";
exit(2);

sub IndicatesSuccess() {
  my $Response = shift();
  if($Response =~ /2\d\d/) {
    return(1); 
  } else {
    return(0);
  } 
} 

sub GetRandomMirror() {
  my @Mirrors = (
	"http://xplanet.sourceforge.net/clouds/clouds_2048.jpg",
	"ftp://mirror.pacific.net.au/xplanet/clouds_2048.jpg",
	"http://www.ruwenzori.net/earth/clouds_2048.jpg",

	"http://xplanet.explore-the-world.net/clouds_2048.jpg");
  return $Mirrors[rand scalar(@Mirrors)];
}

Pas de problème pour initier le script en console :

sudo perl /home/jf/bin/download_clouds.pl

Le fichier "clouds.jpg" est correctement téléchargé, il apparaît dans /usr/share/xplanet/images

Ensuite, j'ai modifié le crontab pour un téléchargement toutes les 3 heures, en ajoutant la ligne suivante :

49 2,5,8,11,14,17,20,23 * * * root perl /home/jf/bin/download_clouds.pl 2&> /dev/null

Enfin, voici la ligne de commande dans les options avancées de kdesktop :

xplanet --geometry %xx%y --num_times 1 --latitude 42 --longitude 2 --output %f.jpg && mv %f.jpg %f

Voilà l'état d'avancement, mais ça ne marche pas. J'ai bien l'image de la terre en écran de fond, mais aucun nuage n'apparaît.

Quelqu'un aurait-il une idée ?

Merci d'avance pour ce soutien planétaire !

Re : xplanet sur Feisty

Salut à toi,
Bon je suis désolé, je ne viens pas t'aider en tout cas pas pour l'instant mais pour demander ton aide.

J'ai installé xplanet avec synaptic. Je cherche à le configurer : j'ai donc créé un script comme dit sur ce forum : http://xplanet.sourceforge.net/FAQ.php#gnome2 pour gnome2. Malheureusement, toujours le même problème, à l'ouverture de session, la terre s'affiche 2 ou 3 secondes puis disparait. J'ai changé le

if [ -z $PROJECTION ]; then 
xplanet -num_times 1

en num_times 10 mais sans succés.
Comment as-tu fait?? je suis curieux!
Merci

Aîe aïe, je crains de ne pouvoir t'aider, étant trop novice sur ces questions. La seule chose que je peux te donner est le script de download des nuages :

Pour ce qui est de l'affichage de ton fond d'écran, j'ai l'impression que c'est ailleurs que cela se joue, mais je n'en sais pas plus... désolé !

Tu trouveras peut-être ton bonheur ici : http://nguild.org/tiki-index.php?page=Xplanet
