I'm currently trying to visualize information from the kinect camera in rviz and just nothing is showing up, not even the robot model (although checking "Collision Enabled" does produce a red-colored robot silhouette). Although things like Image and Camera say they are receiving images, they don't display them at all. Laser scan produces some incomprehensible flashing colored geometric planes across the grid (which I think is still wrong), but PointCloud, DepthCloud etc show nothing. I'm using hydro and following the ROS turtlebot tutorials.

Before opening rviz (with roslaunch turtlebot_bringup 3dsensor.launch) I run:

rosrun opennicamera openninode

and

roslaunch turtlebot_bringup 3dsensor.launch

Both of which display the following warnings:

[ WARN] [1402603782.693472974]: Camera calibration file /home/turtlebot/.ros/camera_info/rgb_0000000000000000.yaml not found.
[ WARN] [1402603782.693805262]: Using default parameters for RGB camera calibration.
[ WARN] [1402603782.694144981]: Camera calibration file /home/turtlebot/.ros/camera_info/depth_0000000000000000.yaml not found.
[ WARN] [1402603782.694272849]: Using default parameters for IR camera calibration.

I've tried changing the fixed frame and it has no effect. Also, running

rosrun imageview imageview image:=/camera/rgb/image_color seems to work just fine and produces an image, despite the exact same image topic in rviz only producing a black screen.

Any ideas? I feel like it must be something very simple but I have no idea what I'm doing wrong.
