can't get clean url to work on ubuntu 10.04

http://drupal.org –

Hi,
I have been trying for a few days to get clean url module working on my vps.
The vps is running ubuntu 10.04, and runs a few applications on virtual host.
I want to create the drupal site on a virtual host as well and it works fine, but I have not been able to enable clean url.
I have of course enabled the module.
I have read and tried many of the suggested documentations but none worked.
here are are the relevant config files

cat /etc/apache2/sites-available/
default default-ssl dev1.mydomain2.com ssl www.mydomain.com www.my-domain.com www.mydomain3.com
root@myserver:~# cat /etc/apache2/sites-available/www.my-domain.com
NameVirtualHost my-ip:80

ServerAdmin webmaster@localhost
ServerAlias my-domain.com
RewriteEngine On
RewriteOptions inherit
DirectoryIndex index.html
DocumentRoot /var/www/my-domain/

if using awstats

we want specific log file for this server

CustomLog /var/log/apache2/www.my-domain.com-access.log combined

AllowOverride All

RewriteEngine on
RewriteBase /my-domain
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]

AccessFileName .htaccess

cat /var/www/my-domain/.htaccess
