    Hello.

    I disabled the x server with the command : sudo systemctl set-default multi-user.target

    following this guide :

    https://www.nomachine.com/AR02R01074

    because I had a lot of flickering inside the NoMachine window. What you suggest to me to do now ? I should re enable it ? but why if now it works fine ? I tried all these pipelines and no one worked right now :

    gst-launch-1.0 -e videotestsrc ! nvivafilter cuda-process=true customer-lib-name=”libnvsample_cudaprocess.so” ! ‘video/x-raw(memory:NVMM), format=(string)NV12’ ! nvoverlaysink
    nvbuf_utils: Could not get EGL display connection
    WARNING: erroneous pipeline: could not link videotestsrc0 to nvivafilter0

    gst-launch-1.0 -e videotestsrc ! nvivafilter cuda-process=true customer-lib-name=”libnvsample_cudaprocess.so” ! ‘video/x-raw(memory:NVMM), format=(string)NV12’ ! nvoverlaysink
    nvbuf_utils: Could not get EGL display connection
    WARNING: erroneous pipeline: could not link videotestsrc0 to nvivafilter0

    Setting pipeline to PAUSED …
    Using winsys: x11
    ERROR: Pipeline doesn’t want to pause.

    this seems to be the better one…

    gst-launch-1.0 nvarguscamerasrc ! ‘video/x-raw(memory:NVMM),width=3820, height=2464, framerate=21/1, format=NV12’ ! nvvidconv flip-method=0 ! ‘video/x-raw,width=960, height=616’ ! nvvidconv ! xvimagesink -e

    since it produces something like this :

    but anyway there is something wrong.

    Now I have. Yes, I have fixed the flickering problem. I have one further thing to understand : how to switch automatically the mouse cursor from the ubuntu / jetson nano / os to the Windows 10 / NoMachine client OS and viceversa, automatically without to press a shortkey combinations of keys. Thanks.

    Hello. I’ve just bought the dummy plug model EZDIY-FAB HDMI and I’ve attached to the jetson nano HDMI port. And under Ubuntu I went under monitor setting and I have chosen : “HDMI-0, resolution 1920 x 1080,refresh rate 60. In addition, I went under the display configuration panel of NoMachine and I’ve chosen “adapt to the window” ; I have also clicked on “modify display settings” and I have chosen “use a custom resolution to 1920 x 1080” ; quality = better. But the flickering problem is still there.

    ok. but the point here is if I can fix it,because I don’t have an additional monitor to attach to the jetson nano.

    When I use nomachine I detach the monitor from the board and I see the flickering. If I use the board with the monitor attached,without NoMachine,I don’t see the flickering. I’ve attached a video to show you what I mean for flickering.

    – NoMachine product (7.0.211) and version on local : Windows 10

    – NoMachine product (7.0.211) and version on remote : ubuntu 18.04 for arm 64 (on jetson nano)

    – Whether the problem arises connecting to a physical or a virtual display : it happens when I connect the NoMachine client on Windows 10 to a NoMachine server running on ubuntu / jetson nano

    – Remote and local Windows/Mac/Linux version (Windows XP/7/8, OS X 10.x, Ubuntu xyz, Mint x.y, etc.) : client = Windows 10 ; remote server = cinnamon on ubuntu 18.04 for arm 64 (nvidia version)

    – If on Linux, desktop version (GNOME. KDE, whatever) on client and on server : cinnamon
