Xlib: extension "NV-GLX" missing on display "localhost:11.0"

Hi.

Every time I start a ssh session I received this 3 lines:
Xlib: extension “NV-GLX” missing on display “localhost:11.0”.
Xlib: extension “NV-GLX” missing on display “localhost:11.0”.
Xlib: extension “NV-GLX” missing on display “localhost:11.0”.

Everything looks to work fine, just those lines at the begin. I guessing it is about try to execute some graphics functionality in my host machine, but my host machine is Windows, so I don’t have this extension installed.

Maybe this topic is not new, here is the closest to a solution I found:

but at the end there is not a solution in this thread.

I am not using any desktop, in fact I removed gdm. I had this problem before remove it. Remake all the system is not a solution for me because there are codes from different developers.

Any help or idea?
Thanks!

If you revmoe gdm, then what did you install on yoru side?

nothing, I am not using any GUI. But I have this problem before remove the gdm.

You still need to run something like startx or xinit because the application you want to use still needs X11 as protocol. Gdm was helping you enable that but you disabled it.

first, I am sorry for the delay in my answers, for some reason I am not receiving the notifications.
I am not using any GUI, I am only access remotely by a terminal connection. Sometime and just for debugging, I need to forward the X-11 to my host machine (export DISPLAY=:0.0) when I do that I received this message.

If you don’t use any “GUI” then what do you want to forward to your host terminal?

If this is just a console, then you don’t need x11 forwarding but just the ssh console…

What is the exact usecase here? You want to render something and forward to your host side?

Or just a ssh and you don’t know why there is error coming out?

Or did you accidentally set x11 forwarding and you didn’t know that?

I have some stuff working with OpenCV. Sometimes I need to see some images.

If you needed GPU access I recommended use nomachine https://www.nomachine.com/
Download arm8 deb https://www.nomachine.com/download/linux&id=30&s=ARM
And install by sudo dpkg -i nomachine_7.10.1_1_arm64.deb

With nomachine in you host system to nomachine Nvidia jetson nano can remote using the NX protocol for X11 protocol access and fully view Desktop .

my host computer is Windows

Nomachine for Windows it’s here https://www.nomachine.com/download/download&id=8
And also install the deb arm64 in you nvidia jetson nano https://www.nomachine.com/download/download&id=113&s=ARM
