Mais quand j'essaie de faire :

bussiere@kusanagi [22:03:53] [~/script] [master *]
-> % xrandr --output Screen\ 0 --primary
warning: output Screen 0 not found; ignoring
bussiere@kusanagi [22:04:49] [~/script] [master *]
-> % xrandr --output Screen 0 --primary 
xrandr: unrecognized option '0'
Try 'xrandr --help' for more information.

ça ne marche pas. Comment saisir correctement l'écran 0 pour la commande --primary de xrandr ?

Merci
