[Bug 710144] [NEW] Xsession: unable to launch "" X session --- "" not found; falling back to default session.

 

Public bug reported:

Binary package hint: xorg

I recently both got an upgrade for Xorg and went to KDE 4.6 (via the
PPA), so I don't know who caused this message to appear. But now
everytime I logon I get an xmessage telling me "Xsession: unable to
launch "" X session --- "" not found; falling back to default session."

This is from /etc/X11/Xsession.d/20x11-common_process-args but I don't
know where the session name comes from. Anyway, I think an empty session
name should be special cased with something like the following
(untested) patch:

--- 20x11-common_process-args.orig      2010-03-02 17:33:01.000000000 +0100

         # Default behavior was requested.
         ;;
       *)

Apart from that it would be nice if that message gave me a hint on how
to fix this.
