Update 2 : I see the same behavior if I virtualize the same debian VM on linux with qemu + kvm. So,it does not depend about freebsd + bhyve.

[ziomario]

UPDATE : There is a workaround to fix it,to stop and start the nx server,like this :

sudo /etc/NX/nxserver --shutdown

sudo /etc/NX/nxserver --startmode manual

sudo /etc/NX/nxserver --restart

but it is uncomfortable. I don’t understand why it works like this and how to fix it.

7.0.211 on arm64 (jetson nano) ; I try to change the GW port directly from the GUI on the section server port,gateway port. You can see on the image that I have attached that the port is set to : 23960. I tried to change the value from there,but the change does not stick. When I go back and I come back to the same section or after having rebooted the nano, I always see the same port : 23960.

My mobile provider does not supports the nat. So, do u know a workaround for this ?

The Ip which starts with 10 is not the external IP of my mobile connection. Im not sure which kind of IP is this. it seems an internal ip,such as 172 or 192. As I said, the external IP of my mobile connection starts with 5. I can see it going on the website ‘www.showip.net’

[ziomario]

I don’t know which kind of IP is the one that starts with 10. Usually, my external IP starts with 5.

[ziomario]

Which IP number should I use? The external one? The IP number that I get going on the website: ‘https://showip.net/’? On port 4000? I did it. It does not work because the error “a connection timeout while trying to connect to “external ip” on port 4000.

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
Setting pipeline to PAUSED …

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 :

https://forums.developer.nvidia.com/t/resolution-problems-with-the-camera-imx219-77ir-mounted-on-the-jetson-nano/165140/5

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.

[ziomario]

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.

[ziomario]

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
