Hello,
I have a custom carrier board which is developed for Jetson TX-1. My requirement is two different VGA output on two monitors.
I have a free PCIe interfaces on our custom carrier board. We have connected a PCIe to VGA converter to connect other monitor. I am using VL-MPEe-V5 from Versalogic which is based on Silicon Motion SM750 chipset.
Jetpack version for my Jetson TX-1: # R32 (release), REVISION: 3.1, GCID: 18186506, BOARD: t210ref, EABI: aarch64, DATE: Tue Dec 10 06:58:34 UTC 2019
I am using sm750fb driver from kernel source /kernel-4.9/drivers/staging/sm750fb/. I am using this driver as a module. The driver is create a node in the /dev/fb1.
The kernel module for sm750fb show in below:

Now problem is, monitor connected over the PCIe to VGA adapter is not detected in Jetson TX-1.
gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-raw,format=YUY2 ! nvvidconv ! 'video/x-raw(memory:NVMM), width=1920, height=1080, format=I420' ! nvoverlaysink display-id=0
I am using above gstreamer pipeline to render usb camera video stream on the monitor. Our Jetson TX-1 is also connected with a monitor through HDMI. The pipeline worked fine with in the HDMI monitor but when I changed the display-id=1 in the pipeline the other monitor is not rendering the usb camera video.
How can I detect the other monitor on Jetson TX-1?
Please help me to solve this problem.
Thanks,
Asif Ikbal
