Description of problem:
I have set up KDE to start with compiz enabled by adding the following to
~/.kde/Autostart

harald@c-15b1e055 Autostart]$ cat compiz.desktop
[Desktop Entry]
Encoding=UTF-8
Exec=compiz --display $DISPLAY --replace gconf & gnome-window-decorator &
GenericName[en_US]=
StartupNotify=false
Terminal=false
TerminalOptions=
Type=Application
X-KDE-autostart-after=kdesktop


This works just fine for the first session I start. But if I use the "Switch
User - Start a new session" function in KDE to log into another X session compiz
fail. Any programs launched opens with no titlebar, so the can not be
moved/closed etc.

If I try to run desktop-effects to enable/disable the effects, this will return
an error if I try to do so in a second session.

If compiz is enabled in the first session or not does not matter.

I have also verified that the results are the same in Gnome.


Version-Release number of selected component (if applicable):
compiz-0.0.13-0.32.20060817git.fc6
xorg-x11-drv-ati-6.6.2-4.fc6

How reproducible:
Every time.

Steps to Reproduce:
1. Start a KDE or Gnome session via gdm.
2. Start a new session by using either "Switch User - Start a new session"
function in KDE or "Applications - System - New Session" in Gnome.
3. Log into the second session and try to enable desktop effects using either a
KDE Autostart file, or the desktop-effects application.
  
Actual results:
compiz only work for the first session.

Expected results:
Should be able to configure compiz to run on any given session, and on several
sessions.

Additional info:
I have also tried a Autostart file where I do not specify display for compiz,
this give me the same result.
