Hokuyo + RViz, Strange Output

edit

Hello everyone.

I am running Diamondback installed via apt-get on Ubuntu 10.10. I installed the hokuyo_node (laser drivers package via apt-get) and connected my Hokuyo 04LX-UG01 to the machine.

While starting the hokuyo_node as indicated by the tutorial, and looking at the output in RViz, I only see one straight red line of points. The line doesnt move if I rotate or move the camera around. This behaviour is the same, independent if I start Rviz with: "rosrun rviz rviz -drospack find hokuyo_node/hokuyo_test.vcg" or just as "rosrun rviz rviz" and using a custom tf base link to laser broadcaster.

I forgot to say that if I move my hand near the laser, the points do move and disappear, making the line shorter or larger, but always on 1 dimension.

EDIT: Even if I change the view to FPS or Orbit and move the camera around, the line stays at the same size and position.

Here is an image of the RViz window for clarity.
