In another thread, NVIDIA said that the Jetson supported up to three displays, through the HDMI port the the two USB-C ports.
I plugged in a USB C / HDMI adapter into the port on the back (next to the GPIO pins) of the devkit, and attached a 1080p display. I then rebooted the Xavier. However, it only provides signal on the HDMI output, and xrandr doesn’t see the display as connected:
nvidia@xavier:~$ xrandr Screen 0: minimum 8 x 8, current 1024 x 600, maximum 32767 x 32767 HDMI-0 connected primary 1024x600+0+0 (normal left inverted right x axis y axis) 150mm x 100mm 1024x600 43.07*+ DP-0 disconnected (normal left inverted right x axis y axis) DP-1 disconnected (normal left inverted right x axis y axis)
(Yes, the HDMI display is a 1024x600 touch panel. Small enough to ride along on the rover!)
How can I attach a second screen?
