through that, instead of using GNOME OSD.

 If you want to leave volume management to any desktop environment you might
 be running, set HANDLE_VOLUME to 0.
 
-To get nifty osd overlays on changing the volume, switching on wireless
-etc. change ENABLE_OSD to yes in /etc/default/eeepc-acpi-scripts. Make sure you
-have aosd-cat installed then.
+You will get notifications of changes in the hardware through libnotify, 
+if available. If you do not want that, set ENABLE_LIBNOTIFY to no.
+
+Alternatively, you can get the same notifications through GNOME OSD. 
+To disable that, set ENABLE_OSD to no in /etc/default/eeepc-acpi-scripts.
+
+You need to have aosd-cat installed in order for GNOME OSD to work.
