[ubuntu-in] [CROSS-POST] How do I run Compiz on *buntu 6.06?

[Roshan]

All,

I installed ubuntu-desktop package (the GNOME env.) on
my Kubuntu so, that I could have GNOME and KDE
together (for any demos). 

I installed compiz, that is three packages
compiz
compiz-gnome
compiz-kde

I also installed Xserver-xgl; (since Xgl is a
pre-requisite for Compiz).

According to the documents on Ubuntu's help website
(http://help.ubuntu.com) I wrote a small script

#!/bin/bash
compiz --replace gconf &
gtk-window-decorator --replace

and put this file in /usr/local/bin/ and assigned it
executable permissions. 
For GNOME, I added the necessary lines in
/etc/gdm/gdm.conf-custom

That is the following lines
[servers]
0=Xgl

[server-Xgl]
name=Xgl server
command=/usr/bin/Xgl -fullscreen -br -accel xv:pbuffer
-accel glx:pbuffer
flexible=true

Also, added Compiz to start by default using
"Sessions" in GNOME.

However, I'm not able to see any effects (not even the
basic ones) and I *guess* Compiz isn't even starting
up!

Am I missing something here? 
Are there any additional steps?

I also tried enabling compiz in KDE, but there's just
one problem. 
There's a small line change in 
/etc/kde3/kdm/kdmrc 
ServerCmd=(all that content)

And then at a command line (when I assume Xgl is
enabled after a log-off and log-in) I issue the
following command

kdm --replace=compiz 

What happens after this is that each window's title
bar disappears, also disabling any keyboard input :-/

I have tried searching quite a few documents. Most of
them speak only about GNOME, and most are about NVIDIA
and ATI cards. 

My video card is a SiS 650 and I have shared 32 MB of
my Physical RAM to it. 

Thanks in advance.
