Hi Aaron,
If you are not publishing tf messages you need to make sure the fixed_frame and target_frame in rviz are set to the frame in which you are publishing thes scans. In the case of the 2nd tutorial you linked to it should be "laser_frame"
Also in the LaserScan display there is an error field with information if it cannot display anything. This should tell you why rviz cannot update the display. If you're still having trouble please send that message in your reply.

but... can I display directly in rviz a "sensor_msgs/LaserScan" message ?? or I need too the "/tf [tf/tfMessage]"
because in the tutorial of
http://www.ros.org/wiki/laser_pipeline/Tutorials/IntroductionToWorkingWithLaserScannerData#Visualizing_Your_Laser_Scan,
I can display the data in rviz without problem (using laser.bag --> http://vault.willowgarage.com/wgdata1/vol1/wiki_docs/laser_pipeline/laser.bag ).
But with the code of this example
"http://www.ros.org/wiki/navigation/Tutorials/RobotSetup/Sensors#Writing_Code_to_Publish_a_LaserScan_Message",
I have problems to display the fake data generated by this code.
Why????

There's a section in the tutorial "Introduction to Working With Laser Scanner Data" that covers this: http://www.ros.org/wiki/laser_pipeline/Tutorials/IntroductionToWorkingWithLaserScannerData#Visualizing_Your_Laser_Scan

I am with this example, and I want to show the fake data in rviz, but I don't know how can do it.

I am trying display the data, because later I will try to write a new driver for a old Laser hardware (PLS200-214)
Thanks.
Best regards...
