Ubuntu – Is Compiz compatible with Xfce

I wrote a small code that shows a notification on workspace switch action. This code requires libnotify and libwnck

To compile it use the command:

gcc -O2 -o wsnd `pkg-config  --cflags --libs libnotify --libs libwnck` wsn.c

If you found compiling errors with above command, try this one:

gcc -O2 -DWNCK_I_KNOW_THIS_IS_UNSTABLE -o wsnd `pkg-config  --cflags --libs libnotify --libs libwnck-1.0` wsn.c

To test it from a terminal: ./wsnd

Include it as XFCE startup application: In XFCE you need to add it as startup applicaion on settings-manager->session and startup -> Application Autostart

The code:

   gdk_init (&argc, &argv);

   loop = g_main_loop_new (NULL, FALSE);
   screen = wnck_screen_get_default();

   g_signal_connect (screen, "active-workspace-changed",
                    G_CALLBACK (on_active_workspace_changed), NULL);

   g_main_loop_run (loop);

   g_main_loop_unref (loop);    

   return 0;
}

The following works for me:

sudo apt-get install compiz gnome-themes compizconfig-settings-manager
compiz --replace ccp &

If there are any errors displayed in the terminal, please add the output into your question.
