No monitor output after quickstart with IMX636 and kv260

No monitor output after quickstart with IMX636 and kv260

I have set up the IMX636 with the kria board via usb (uart connection) and also it is conenct via ethernet to the router, not the laptop directly since I have no possibility to do this, nevertheless I can ssh into the device no issue or via serial interface. 

Via ssh i run 
  1. V4L2_HEAP=reserved V4L2_SENSOR_PATH=/dev/v4l-subdev3 metavision_viewer

and it opens the metavision viewer without issues. But when I try it via serial with

  1. Xorg &
  2. DISPLAY=:0.0 V4L2_HEAP=reserved V4L2_SENSOR_PATH=/dev/v4l-subdev3 metavision_viewer

I see no HDMI output without any info, and connecting DP shows:

Feb  3 01:48:59 xilinx-kv260-starterkit-20222 kernel: zynqmp-display fd4a0000.display: failed to configure links
Feb  3 01:48:59 xilinx-kv260-starterkit-20222 kernel: zynqmp-display fd4a0000.display: failed to train the DP lk

And heres the output when I start the metavision viwer:
  1. DISPLAY=:0.0 V4L2_HEAP=reserved V4L2_SENSOR_PATH=/dev/v4l-subdev3 metavision_viewer
  2. Simple viewer to stream events from an event file or a device, using the SDK Stream API.
  3. Define a region using the cursor (click and drag) to set a Region of Interest (ROI)
  4. Press SPACE key while running to record or stop recording raw data
  5. Press 'q' or Escape key to leave the program.
  6. Press 'o' to toggle the on screen display.
  7. Press 'l' to load the camera settings from the input camera config file.
  8. Press 's' to save the camera settings to the output camera config file.
  9. Press 'r' to toggle the hardware ROI mode (window mode or lines mode, default: window mode).
  10. Press 'R' to toggle the ROI/RONI mode.
  11. Press 'S' to toggle the subsampling.
  12. Press 'e' to toggle the ERC module (if available).
  13. Press '+' to increase the ERC threshold (if available).
  14. Press '-' to decrease the ERC threshold (if available).
  15. Press 'h' to print this help.

  17. [HAL][INFO] V4l2 Discovery with great success +1
  18. Plugin used to open the device: hal_plugin_prophesee
  19. Camera has been opened successfully.
  20. [HAL][INFO] V4l2DataTransfer - start_impl()
  21. [HAL][INFO] V4l2DataTransfer - run_impl()
Another hint is that the keyboard attached to the kria works, i.e. if I press h the help screen is streamed to the serial interface and if i press q it also exits it (although some times it works others it doesnt react).

Also this might be interesting:
