Hello all, really hope you can help me!
I have Ubuntu 13.10 in my work PC, but now when I login, it enters a black screen saying
NX> 161 Enabled service: nxserver
NX> 161 Enabled service: nxnode
NX> 161 Enabled service: nxd
and 3 lines starting with PDISP][…
Then it comes back to login screen – so I cannot enter! I can enter as guest. This happened while trying to make remote-desktop to it from my Windows laptop (a long-time desire and still couldn’t). The only things I (think) I did in Ubuntu was to install xrdp and tightvncserver. Then this happened after “shutdown -r now”…BTW upgrading the Ubuntu’s programs/packages is not something I have done in last years.
After googling the error code, I found some similar reports in this forum. I don’t understand nothing of Linux.. I can enter in my account from ssh, so I could try some commands if you could help 🙁
Really hope you can help. Thanks in advance.
December 14, 2018 at 12:51 #20810kroyContributorHi.
We couldn’t reproduce problem on Ubuntu 13.10 in our labs, not even connecting to a headless machine. From the description, it seems like a crash of the xserver, not NoMachine.
After googling the error code, I found some similar reports in this forum.
Which error code? Can you tell what NoMachine version is installed there?
Can you create new user and log in to that user’s desktop locally? If you can, please also try connecting via NoMachine.
December 14, 2018 at 15:27 #20818troubleParticipantHello,
The error code I googled was “NX> 161 Enabled service: nxserver”, and it all come back to this forum.. so I posted here in hope of some help..
The version of NoMachine is 4.6.12.
I have created a new user and can log in to that user’s desktop locally (in last option I could try to move everything to that user and work there, but still would be nice to fix this…).
I installed NoMachine probably in a previous attempt to remote-desktop, but never with success. So, I have never used NoMachine and not sure what you mean by “connect via NoMachine”.
December 14, 2018 at 15:27 #20819troubleParticipantIf I enter locally in the newly created user, everything works fine. In terminal I can “su – previoususer”, and see all my documents. So I can work semi-locally. But, at this point, I am afraid of trying any code…
Would you advise uninstalling NoMachine:
sudo dpkg -r nomachine
Or any of these?
The NX server should start at boot up, you can stop it with this command:
/etc/init.d/nxserver stop
You can permanently remove it from starting with this command:
update-rc.d -f nxserver remove
December 14, 2018 at 15:52 #20824kroyContributorTo completely remove NoMachine you can execute:
sudo dpkg --purge nomachine sudo rm -rf /usr/NX /etc/NX
We strongly recommend you update to the latest which is version 6.4.6, firstly because we no longer support v4 ; and secondly it’s better to use a more recent version for fixes and its new features etc
“NX> 161 Enabled service: nxserver”
This is not an error. It simply console output which tells you that NX is running on the host.
Make sure you are using the latest version of NoMachine on both the connecting client and remote server. Then tell us if you still have the same problem.
