But can I force NoMachine to use the onboard GPU instead of the NVIDIA one? Because this is unusable, besides the glitches it also becomes very laggy.

E-mail is sent!

 

System specifications:

Linux server: i5-2400, 8GB RAM, NVIDIA GT 1030 and GTX 1650 (both GPU’s tested)

Windows client: i7-8700K, 32GB RAM, GTX 1080ti

I just discovered this was split into a new topic, so sorry for the late response.

You want my hardware details?

I also have recorded the issue on my screen, so I can send that through e-mail if that’s helpful?

Hey Brit,

You’re probably right. Although it seems already to be fixed. It’s pretty weird, with no monitor connected to the Linux machine I get those performance issues. But as soon as I connect my TV (even on standby), the problems are over and I get full screen in 1080p and a smooth experience.

Is there a logic to that? That NoMachine has a problem with headless machines? Also if I add a GPU to my system instead of using an onboard (i)GPU, would the GPU still do the work without a monitor or TV connected? Or the TV on standby? Or is that the X-server thing you’re talking about?

Also, as a conclusion I would like to know what I did wrong in the end. Was at simple as this?:

If you want to use system authentication, than remove ‘#’ from that last line, it should say:

EnablePasswordDB 0

It’s ‘full screen’ now, but it’s in a low resolution (Fit to screen). The display settings mention ‘1024 x 768, codec H.264’ in the left bottom while there is no monitor connected to the Linux machine. All the options are unchecked, except ‘Use custom resolution upon connecting’, but that doesn’t seem to do anything. I have a 2560 x 1440 monitor and I would like the Linux machine to be in the same resolution, is that possible?

It’s also extremely slow/laggy to the point it’s basically unusable. Can I fine tune the network and/or fps settings to make it go smoother then this? I often use [removed] to help people remotely and even that is way faster then this. And that’s over the internet… So I feel it should be possible to run NoMachine with the NX protocol over LAN way faster.

Thanks in advance

I got it working (again), for some reason ‘accepting connection(s)’ was disabled on the Linux machine. I didn’t to this myself as far as I know, so no clue why this happened.

I still don’t have full screen though, despite manually entering the resolution. But currently the Linux machine is connected to a 640×480 (back up) monitor, so that could be the issue. I’ll test tomorrow without a monitor connected to the Linux machine.

It worked, now I just wanted to try it again and I get this error:

“The session negotiation failed”.

What’s that all about?

[Zenith]

How can I make it fullscreen btw? When I click fullscreen now, I still get like a 15″ screen on my 27″ monitor on my Windows PC.

[Zenith]

It works now!!! Omg.

I have to do a clean install now on my Windows machine, if I install NoMachine and it works again I will report back here! 🙂

[Zenith]

Ok, I followed all the steps and e-mailed the results.

[Zenith]

I get:

NX> 500 ERROR: Cannot enable debug mode for: server.
NX> 500 ERROR: Key SessionLogLevel does not exist in /usr/NX/etc/server.cfg.

How can I fix that or what should I do next?

Hey brotech,

I collected all the files you requested and e-mailed them. I wasn’t able to copy nxserver.log at first, so I ran this command to get that file:

sudo /etc/NX/nxserver –debug –collect

After that I tried again and then I could copy the nxserver.log file. but just in case I also added the zipped debug log file.

If you need any more information, please let me know!

[Zenith]

Here are the results:

oem@Zenith:~$ whoami
oem
oem@Zenith:~$ /usr/NX/bin/nxexec --auth
Username:oem
Password:
*********
User authorized, is member of: oem,adm,cdrom,sudo,dip,plugdev,lpadmin,sambashare.
oem@Zenith:~$

I hid my password, but it’s correct. These are the credentials I used from the beginning. So chances are it’s a problem with the client side (my Windows PC)!?

And strange that the log only mentions ‘oem@Zenith’, because like I said. I tried: oem, oem@Zenith, Zenith, Zenith\oem

All with the same password, but it all results in the same authentication error.

I also checked again with a fairly new laptop with a fairly clean install and same error with the correct credentials.

[Zenith]

I also tried ‘oem’ and ‘Zenith’. Last is the machine name I suppose. I will try the other things as soon as I can, thanks!

[Zenith]

It still doesn’t work, so I’ll send the log and debug files. I ran these two commands:

sudo /etc/NX/nxserver –debug –collect
sudo tar cvfz NoMachine-log.tar.gz /usr/NX/var/log

With the sessionloglevel set to 7 and sessionlogclean to 0 (zero). If you need any more information, please let me know.
