No display on CentOS

[nomachine_user999]

I am an enterprise user of NoMachine, and I am connecting to a headless CentOS (Linux release 7.9.2009) VM from a MacBook Pro (Sonoma 14.3.1). Remote CentOS box has Gnome display manager installed and running, but NoMachine does not detect it and run it. It just shows a black screen after connecting.

All packages and softwares are up-to-date.

Hello,

as an enterprise user you also have the option to open a support enquiry from your customer area.

Take a look at the tips here for headless Linux hosts:

https://kb.nomachine.com/AR03P00973

If the tips there don’t help, then we’ll need logs from the Linux side. You can extract them using the instructions here: https://kb.nomachine.com/DT07S00243

Send them to forum[at]nomachine[dot]com. Please use the title of this topic as the subject of your email.

Also the output of
sudo grep -E "DefaultDesktopCommand|CommandStartGnome" /usr/NX/etc/node.cfg

In our environment CentOS 7 default settings show:

DefaultDesktopCommand "/bin/dbus-launch --exit-with-session gnome-session --session=gnome"
CommandStartGnome "/bin/dbus-launch --exit-with-session gnome-session --session=gnome"

Could you please let me know the steps to open a support enquiry from customer area?

I don’t see an option and clear steps through my NoMachine account here or through my enterprise IT ticketing system.

The forums are currently separate from the Customer Area. So you have two logins: one for the public Forums where anyone can answer, and one for the Support Center for those with valid subscriptions which is a direct line to the NoMachine Support Team. This is going to change in the future when users will only have to register once. In any case, we would still recommend users with subscriptions submit their questions through their customer area rather than the forums.

The steps are:

1) In the Menu, select Get Support

2) insert your Customer ID and password

3) select Support Enquiries in the navigation bar

4) Click Open a Support Enquiry

If you are not in possession of your Customer ID, please write to us via the website (Contact us) and include the License Id from the license file you are using.
