 The ''sleep'' command is just used to print the new value after the change. ''cut'' is used to extract the value of the volume for the bar graph.
+===== Configure TwinView/Xinerama/DualScreen =====
+First, emerge fluxbox with the ''xinerama''  USE flag (and you should compile everything with this flag, so set it in ''/etc/make.conf'').
+It will work fine, except that your toolbar could be spread on both screens, then change in ''~/.fluxbox/init'' :

-===== Patch for double-click maximize and meta-tab =====

+Fluxbox deals with workspaces in a quite simple manner: when switching workspace, it hides all windows of the old workspace, and then draw all windows of the new workspace.

+Most of the time when we switch workspace, we can see the background image, and then all new workspace windows displayed one after the other, what is very nasty.

+Third thing, only redraw what is necessary (seems to be faster, but I'm not completely sure, and I hope it doesn't break anything) by replacing the deiconify function by a unwithdraw function which does only a fraction of what deiconify does:
+<code cpp>
+Workspace.cc:228
+-        (*it)->deiconify(false, false);
++        (*it)->unwithdraw();
+Window.hh:201

++    m_blackbox_attrib.flags &= ~ATTRIB_HIDDEN;
++
++    setState(NormalState, false);
++
++    show();
++
++    oplock = false;
++}
+</code>
+I have also tried to draw and clear windows in their general order of focusing, in replacement of the 2 first enhancements, but surprisingly it's less convincing:
+<code cpp>
+Screen.cc:1211
+-    currentWorkspace()->hideAll(false);
++    int workspace = currentWorkspaceID();
+     // set new workspace
+     m_current_workspace = getWorkspace(id);

++    FocusControl::FocusedWindows::iterator it2_end = focusControl().focusedOrderList().end();

++    for (; it2 != it2_end; ++it2) {

++	{
++            if ((int)(*it2)->fbwindow()->workspaceNumber() == id)
++	        (*it2)->fbwindow()->unwithdraw();
++            if ((int)(*it2)->fbwindow()->workspaceNumber() == workspace)
++	        (*it2)->fbwindow()->withdraw(false);
++	}
++    }
+-    currentWorkspace()->showAll(win->fbwindow());
