tried everything short of actually calibrating in xubuntu 12.04 + hydro, nothing worked. BUT SUCCESS! >> after a fresh install of xubuntu 14.04 and ROS indigo, openni2_launch just works!

Thanks! You've answered my basic compatibility question but I'm now I'm getting a calibration error, please see update to the question

Hi, I have an Xtion Pro Sensor (non 'Pro-Live' version, without RGB camera) and am trying to run:

roslaunch openni_launch openni.launch

It dies immediately with with 'Service Call Failed!' errors.

I'm running Hydro on Ubuntu 12.04. Before I start delving into messing with parameters, wondering if anyone has managed to get the non-rgb Xtion Pro depth camera running with the openni_camera package? Or is it simply not supported?

(I also have a the Pro-Live RGB version of the sensor and it works fine on the same system)

EDIT: The underlying problem was a symbol lookup error which I solved by updating my system. Now I'm running openni2_launch and the camera is recognized, but I'm getting this error on launch:

[ERROR] [1409344784.275581907]: Unsupported color video mode - Resolution: 640x480@30Hz Format: RGB888

and this error when I add a PointCloud2 pointing to /camera/depth/points in Rviz:

[ INFO] [1409345247.761731749]: Starting depth stream.

[ERROR] [1409345248.237372380]: Rectified topic '/camera/depth/image_rect_raw' requested but camera publishing '/camera/depth/camera_info' is uncalibrated

I can't find any easy parameter change fix in the openni2.launch file, do I actually have to calibrate the camera? My Xtion Pro Live RGBD camera gives the same calibration warnings but not the last error shown above

EDIT2: Couldn't get non RGB Xtion Pro working under Xubuntu 12.04 and Hyrdo, I may have been running into this bug, as the error messages match exactly: https://github.com/ros-drivers/openni2_camera/issues/14

But a fresh of install of Xubuntu 14.04 and ROS Indigo did the trick, openni2_launch just works, with default settings.
