Black screen on second monitor

[shekel]

Hello! I use NoMachine server on Ubuntu and NoMachine client on Windows 10. All works but second screen of my connection is black. In nxserver.log I can see this error:

30258 318974 2023-08-29 15:58:48 013.417 HostWmRunningHelper: WARNING! Failed to open display ':0'.

30258 30258 2023-08-29 15:58:48 013.513 NXSERVER WARNING! Cannot check WM on display :0 EEXIST

Hi,

please gather server side logs as exaplained in https://kb.nomachine.com/DT11R00182. You can send them to forum[at]nomachine[dot]com.

Then open the /usr/NX/etc/node.cfg file on the server, uncomment the WaylandModes key and set it to the following value:

WaylandModes drm,compositor,egl

If that doesn’t help, gather the logs again with the changed key.
