Black screen connecting to NX Server on Linux from Mac

[udgrahita]

I seem to be getting a black screen when i connect to the NX Server running on my server. I’ve checked the server logs and I didn’t find anything out of the  blue, well nothing that was obviously wrong for me.

Any help will be appreciated. I’ve the server and client logs too not sure where to send them though.

My server is running ubuntu 14.04, while my client is running OS X El Capitan.

Hello.

You can send the logs to forum[at]nomachine[dot]com.

Is your server a headless machine? Or is it running in a virtual machine?

It’s a headless machine.

So it can happen, depending on the video card, that the X server is running but it is not rendering, because the video card is turned off.

You can try to stop the X server:

sudo service lightdm stop

and restart the NoMachine server:

sudo /usr/NX/bin/nxserver –restart

At this point NoMachine will create its own virtual framebuffer and you should be able to connect and see the desktop.

So I did this but now my nxnode and nxd services wouldn’t start.

NX> 162 Disabled service: nxserver.
NX> 162 Disabled service: nxnode.
NX> 162 Disabled service: nxd.
NX> 161 Enabled service: nxserver.
NX> 162 Disabled service: nxnode.
NX> 162 Disabled service: nxd.

 

I then followed the advice at this page (https://nomachine.com/TR02L04291), but it still doesn’t work. Based on this when I try to connect to the machine I get

2017-05-08 16:55:52 325.340 18199 NXSERVER Cannot send to NXNode. Node is not runned.
2017-05-08 16:55:52 325.347 17983 NXSERVER NXNodeExec::socketserver closing.

which seems logical given that the nxnode is disabled. But I’m not sure why!!

Yeah, that is strange. Please gather NoMachine server side logs as explained in https://www.nomachine.com/DT07M00098. You can attach them here or send to forum[at]nomachine[dot]com.

Thanks for sending the logs. Unfortunately they are not enough to determine what is the problem, since debug logs are disabled. Please follow the instructions of this paragraph: https://www.nomachine.com/DT07M00098#1.

I suggest you update to the latest version and if the problem persists, please open a new topic.
