Hello.
There is one thing that come to mind. Please check if in the client --monitor
options you have the “Lock the physical screen on disconnect” option selected.
On the server-side, i.e the computer you want to connect to, right click the system tray icon -> Show the service status -> Server preferences -> Security, last option on the bottom. If yes please turn it off, restart the nxserver:
sudo /etc/NX/nxserver --restart
and check if the problem is still happening.
If no, please provide logs so we can investigate.
The article on how to collect logs:
https://www.nomachine.com/DT10O00163 (“How to gather debug logs for support requests”)
Please send the logs to forum[at]nomachine[dot]com using the title of that forum’s thread as the mail’s subject.
Also please remember that after enabling logs as in the article you will have to restart the nxserver again and reproduce the problem.
Then you can use
sudo /etc/NX/nxserver --debug --collect
for NoMachine to automatically collect and pack the logs, or do it manually.
