BritgirlKeymasterHi Bob,
there is a known issue with forwarding USB device when the user is not logged on to the desktop on the server side. You can use the following link to track its status: https://kb.nomachine.com/TR05U10850. The current workaround, which I understand can be awkward, is to make sure that the user has not been logged out.

BritgirlKeymasterIf the user is working physically in front of the Linux machine looking at the monitor, using the mouse and keyboard, and then starts a virtual desktop session from their Windows laptop to that same machine (NoMachine Workstation must be installed), they will connect to a virtual display running in the background and completely independent from what is actually showing on the physical display. The monitor will therefore not be blanked.
Screen blanking occurs when a user connects remotely to the physical display. This is why, in the free edition, the screen is getting blanked: the user is starting a physical desktop session to a machine with screen blanking enabled.
BritgirlKeymasterIt seems this is caused by Mate and not NoMachine. Try using a later version of Mate (>1.24) if possible.
BritgirlKeymasterHi, we’re able to reproduce the same behaviour when the Mate panel is version 1.26.4 on Redhat/Rocky and only with virtual desktop session (connecting to a NoMachine terminal server) With other version of Mate we are not able to reproduce it, so it seems to be a Mate issue. Btw, if you’re a subscriber of Terminal Server, you are entitled to open a support enquiry directly from your User Area 😉
BritgirlKeymasterCan you try with
DefaultDesktopCommand "/usr/bin/startxfce4"? I’m not sure if that’s a typo or ‘4’ was maybe missing from your command?
BritgirlKeymasterHi, our developers are already investigating and are working on a fix. I’ll update this topic when I get confirmation from them. Thanks for your patience 🙂

BritgirlKeymasterHi, we have now reproduced the problem and opened a Trouble Report. Here is the link: https://kb.nomachine.com/TR03X11739 which you can use to track its status. Thank you!
BritgirlKeymasterThanks for letting us know. We’ll keep this topic open for a few days more. If you encounter the same problem again, it’s best to start a new topic with fresh details.

BritgirlKeymasterHi, can you send us
1) a screenshot of your display settings in Windows -> Settings -> Display
2) a screenshot of NoMachine’s display settings -> run the session, open the connection menu (ctrl-alt-0) > Display > Display settings
BritgirlKeymasterCan you send us the client-side logs to start with? Connect to the problematic desktop, open the NoMachine connection menu (Ctrl-Alt-0) > Connection Info > Take logs. Send us that file, please. You can attach it here or send direct to forum[at]nomachine[dot]com. So far we have been unable to reproduce this issue in our own test environment.
BritgirlKeymasterApologies, you already mentioned it was Mate. We’re not able to reproduce this issue at all. Can you send us the client-side logs to start with? Connect to the problematic desktop, open the NoMachine connection menu (Ctrl-Alt-0) > Connection Info > Take logs. Send us that file, please. You can attach it here or send direct to forum[at]nomachine[dot]com.

BritgirlKeymasterYou don’t have to disable the second monitor, you can leave it enabled and the use the NoMachine player to select the monitor you want. We’ll continue to investigate, we’ve been unable to reproduce so far.
BritgirlKeymasterThis looks related to the desktop, and not caused by NoMachine. Run
gnome-extensions list -dto know what shell extension is installed and its version.
BritgirlKeymasterThis looks like a desktop issue, caused by the fact that the drawer showing 3rd party application icons has been removed? Please follow the instructions here:
What to do when the !M icon is not present in the system tray of GNOME desktop

BritgirlKeymasterCan you point us to the guide you are referring to? Perhaps you mean the blank screen feature which is for blanking the physical display of the target host?
