Problem running openni_launch on ros fuerte with Xtion pro live

edit

Hi ros user!

I try to use a Asus Xtion pro live with ROs Fuerte and openni_launch. I have made a lot of test but I have not been able to make it work. It is always the same thing I have got this Error message :

[ERROR] [1337435292.200305197]: Tried to advertise a service that is already advertised in this node [/camera/depth_registered/image_rect_raw/compressed/set_parameters]

[ERROR] [1337435292.210206934]: Tried to advertise a service that is already advertised in this node [/camera/depth_registered/image_rect_raw/theora/set_parameters]

Exept this error every thing else seems alright. It detect the camera :

[ INFO] [1337435291.552393164]: Number devices connected: 1
[ INFO] [1337435291.552631121]: 1. device on bus 001:03 is a PrimeSense Device (600) from PrimeSense (1d27) with serial id ''
[ INFO] [1337435291.554548510]: Searching for device with index = 1
[ INFO] [1337435291.687868149]: Opened 'PrimeSense Device' on bus 1:3 with serial number ''

But there is no message publish on the topic /camera/depth/points. I have tried different topics but none of then publish any message. I use RVIZ to see the topics.

I was previously running ros on Ubuntu 10.04 running on VMWare Player. When I encourtered this error I decided to try on different Ubuntu version but I have got the same error on each of the version I have tried.

I have tried Ubuntu 11.04, 11.10 and 12.04. On ubuntu 12.04 I have got much more error so I concentred myself on ubuntu 11.10 which I suppose is the better version of Ubuntu to work with Asus Xtion. I have even try to install ros fuerte from source but it doesn't resolve anything. Still the same error!

Now I don't know what to do. Have I missed something?

I guess that with ros fuerte and openni_launch I have nothing else to install? right? Openni Driver and everything else is package with openni_launch? right?

Any help apreciate.

Things in advance.

Regards.

Christophe.

EDIT TO MY INITIAL POST:

Yes all my previous try where done on VMWare. I have now installed Ubuntu 12.04 directly on my PC and now everything works fine! I am able to see point cloud in RVIZ! Thanks for taking time to answer me!
