    Hello,

    Since 2 weeks ago I cannot access a cloud Kali machine using NoMachine. It worked well before, I didn’t do any system updates on the machine, and suddenly after a reboot it stopped working, meaning i can only see a white blank screen after successful authentication to the machine

    The machine is running Kali Linux 2019.4 with gdm.

     

    Thanks in advance

    What version of NoMachine do you have installed on the server and client sides?

    The server is running ‘nomachine_6.9.2_1_amd64.deb’ package and Windows client is also 6.9.2

    Hi. Please try solution from that article: https://www.nomachine.com/AR03P00973. Turn of X server and restart nxserver.

    sudo service gdm stop
    sudo /usr/NX/bin/nxserver --restart

    To disable X server permanently you can execute command: sudo systemctl disable gdm3.service.

    Hello,

    I’ve already tried that but it didn’t work. Also , i’ve connected to the server using the client installed in the same machine , and i’ve got the same result: blank white screen . So i think it’s not a communication issue ..

    Screenshot indicates that there could be wrong starting command. What is the output of the command grep DefaultDesktopCommand /usr/NX/etc/node.cfg. Please enable debug, reproduce problem and send logs to forum[at]nomachine[dot]com (all that should be done on the server side). There are instructions how to enable and collect debug logs automatically: https://www.nomachine.com/DT10O00162. Make sure you put the title of the topic as your subject.

    Can you write from which cloud service are you using?
