    Iam trying to connect from NoMachine 4.3.30_1.

    When I tried connecting , its showing only black blank screen.

    Please do help to resolve and able to connect successfully.

    Please find below information’s from the linux server,

    [root@ip-172-31-24-96 ~]# ps auwx | grep Xvf

    root 1705 0.1 2.5 109872 15224 pts/0 S 19:24 0:00 Xvfb :0 -auth /root/Xvfb-0.auth -screen 0 1024x768x24

    root 2143 0.0 0.1 103248 864 pts/0 S+ 19:26 0:00 grep Xvf

    You have first one result line which has ‘Xvfb :0′.

    Hi elan,

    unfortunately the logs you sent are not complete and not useful for the investigation. Please send a complete set of logs as explained in details here: If you wish, you can send them to forum[at]nomachine[dot]com by referencing this topic in the subject.

    But before that, can you tell something more? I see you are connecting to a Xvfb display. Is this a headless machine and you followed instructions in Have you launched a desktop environment (or any X application) inside the Xvfb display?
