After spending a few hours with the gksu source code, it seems pretty obvious to me that the problem is that the pop-up is not considered as a new window, but as a tooltip.
>From libgksu's source code: if (context->grab) dialog = g_object_new (GKSUUI_TYPE_DIALOG, "type", GTK_WINDOW_POPUP, "sudo-mode", context->sudo_mode, NULL); >From GTK's documentation >(http://library.gnome.org/devel/gtk/stable/gtk-Standard-Enumerations.html#GtkWindowType): Windows with type GTK_WINDOW_POPUP are ignored by the window manager... many GTK+ features that rely on the window manager will not work... GTK_WINDOW_POPUP is used to implement widgets such as GtkMenu or tooltips that you normally don't think of as windows per se. So this bug seems to be caused by the dialog's lack of window management features. -- When screen is locked, the default language for password entry should be the user's default language https://bugs.launchpad.net/bugs/154744 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-screensaver in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
