How can I change the wallpaper using a Python script?
- by furtelwart
I want to change my wallpaper in Ubuntu 11.10 (with Unity) in a small Python script.
I found the possibility to change it via the gconf-editor in /desktop/gnome/background/picture_filename. With python-gconf, I'm able to change the necessary values.
Apparently, the gconf string is not read out. If I change it (either via a script or via gconf-editor), the wallpaper remains and in the menu of "Change wallpaper", the old wallpaper is shown.
How am I able to change the wallpaper for Unity via a Python script?
The following code does work. Apparently, the gsettings are only applied, if some Gtk code is executed.
#!/usr/bin/python
# -*- coding: utf-8 -*-
from gi.repository import Gtk, Gio
class BackgroundChanger():
SCHEMA = 'org.gnome.desktop.background'
KEY = 'picture-uri'
def change_background(self, filename):
gsettings = Gio.Settings.new(self.SCHEMA)
print(gsettings.get_string(self.KEY))
print(gsettings.set_string(self.KEY, "file://" + filename))
Gtk.Window()
print(gsettings.get_string(self.KEY))
if __name__ == "__main__":
BackgroundChanger().change_background("/home/user/existing.jpg")
