GUI does not show up in stereo calibration of flea3 cameras [closed]

edit

I am having a weird but familiar case. I have two PGR flea3 cameras. I can and have calibrated each of them separately. The problem is when I'm starting stereo calibration, the GUI does not pop up. Here is my launch file to brinup cameras

    <launch>
        <rosparam command="load" file="$(find stereo_cameras)/config/cameras.yaml" />
        <group ns="stereo">
                <node name="left" type="camera1394_node" pkg="camera1394" output="screen" required="true">
                      <remap from="camera" to="left" />
                </node>

                <node name="right" type="camera1394_node" pkg="camera1394"  output="screen" required="true">
                      <remap from="camera" to="right" />
                </node>
        </group>
</launch>

The launch file for calibration looks like this

<launch>
    <arg name="size" default="8x6" />
        <arg name="square" default="0.108" />
        <arg name="approximate" default="0.01" />
        <node pkg="camera_calibration" type="cameracalibrator.py" name="stereo_calibration"
                        ns="stereo" args="--size $(arg size) --square $(arg square) --approximate=$(arg approximate)"
                        output="screen" required="true">
                <remap from="left" to="left/image_raw" />
                <remap from="right" to="right/image_raw" />
                <remap from="left_camera" to="left" />
                <remap from="right_camera" to="right" />
        </node>
</launch>

Executing cameras_bringup.launch I have

NODES
  /stereo/
    left (camera1394/camera1394_node)
    right (camera1394/camera1394_node)

and stereo_calibration.launch I get this

after that no calibration GUI shows up.

I am on hydro, ubuntu 12.04. The computer is new, I have not tried other cameras here. With other cameras and on a different machine such kind of problem occurred when cameras were not synchronised, that time adding approximate = 0.1 helped, but not here.

Does anyone have ideas what could be the issue?

Thanks in advance!

• Edit Still haven't resolved it yet. It is weird that the same launch and config files work fine on my Macbook. I tend to believe it is a hardware issue, as I am using Intel NUC. Moreover on macbook I don't even use software approximation. What it could be?
