I said GNOME, not LXDE :)

GNOME is more than the libraries -- there is also the session stuff, 
panels etc. Basically, you need to start a GNOME session for the 
gnome-osd to work. (Well a full-blown gnome-session may be a bit 
extra, but I don't see the point of finding the minimal set of 
components it takes. After all, it would be as heavy as the full 
session).

Nah, this process is started up automatically when you start the GNOME 
session.

Not a bug. The ’ symbol you pasted from the manual page is not vali 
XML. Use ' instead.


All in all, the gnome-osd support is targetted at users of GNOME (the 
full-blown desktop environment). If you want to run it under LXDE, 
better find an analogous servise for LXDE (lxde-osd, anyone?). I have 
no idea if such thing exists.

If somebody more knoweledgable in KDE than me can hand me a script 
that does OSD the KDE-way, I will happily integrate that too.  XFCE 
too, or whatever you use.
