RVIZ not getting images from camera

I am using a nvidia TX2 computer running ROS Kinetic on ubuntu 16.04. I also loaded the software for a Intel RealSense 435 camera. I followed the install from Jetson Hacks on youtube...works great. https://www.youtube.com/watch?v=_g_F-...

I have a windows PC that I installed ubuntu and ROS on as well..https://janbernloehr.de/2017/06/10/ros-windows

I want to be able to transfer the camera images from a nvidia TX2 computer running a realsense node to my Windows 10 PC running RVIZ in a Xming window. RVIZ launches just fine in a Xming window, but I am getting a GLOBAL Status Warning No tf data. Actual error: Fixed Frame [map] does not exist. When I start the camera in rviz... I get more warnings that there is No Image received.

I am wondering if there is something with Xming that is blocking the images from RVIZ. Some controls like the PointCloud2 and the Grid appear to attach to the realsense TOPICS quiet well. .... but there are just no camera images. I can run rviz on my TX2 computer and I get camera images just fine. It is much more complex of course when I want to pull those images across my local network switch to my windows10 PC running Ubuntu 16 and launching rviz into a Xming window.

I at first thought that I would try to install a virtual machine...but the lag is terrible. Running RVIZ in native ubuntu Xming window on my windows10 operating system has the performance I am looking for.

here is a link in youtube https://www.youtube.com/watch?v=Bd6TB... showing my setup...hopefully it will not add confusion.

Just making sure: the Camera display != Image display. Camera requires TF, Image does not. Which one of these are you trying to use?

Finally: instead of having us watch a video to figure out what you have there, could you insert a textual description? Videos tend to get deleted/disappear.
