The previous answer is incomplete. Setting output="screen" in the launch file will show INFO messages and above, not DEBUG output.
For that, you can set the ROS console configuration.
The rxconsole package allows dynamic setting and resetting of DEBUG output. The "Levels" button near the lower right corner can set each C++ logger to any level. (It has no effect on Python loggers.)
Just set output="screen" in the launch file as mentioned below. I prefer rqt_console over the screen. It's much easier to filter and even pause the output.
In the node definition, you can set the output to screen:
<node pkg="amcl" type="amcl" name="amcl" output="screen"> for example. That will get the output pushed to your console.
You can also often find the information you're looking for through the rxconsole program. It's nice for separating the output from the many nodes that are launched, as well as displaying based on severity (warnings, errors, debugs).
