Cannot detect any display running

[GoodKnight]

Hi – I get the “Cannot detect any display running” message when attempting to connect to the physical display of my Linux workstation.

– Running free version 5.1.26 on both local and remote machines

– Attempting to connect to physical display

– Remote (Server) machine is Linux Fedora Core 23, Local (Client) is Mac OS X El Capitan

– Using GNOME on the FC 23 machine.

[satyen@autarch ~]$ sudo /usr/NX/bin/nxserver –restart

Hello.

The most probable cause for this problem is that Fedora 23 uses Wayland instead of X server. NoMachine is not yet compatible with Wayland, so disabling it is the only way to fix it.

By default Wayland is enabled on Login Window, to disable it for GDM, please edit

/etc/gdm/custom.conf

And under the tag

[daemon]

make sure the only line containing WaylandEnable field is:

WaylandEnable=false

Please let us know if it helps, or if the problem persists after disabling Wayland.

Thanks.  That solved the connection issue but now I am faced with black screen after logging into the remote machine.

I found this thread with changing gdm->lightdm…is this the correct solution?

It could help. Try it and let us know.

You should update to the latest version in any case. Let us know if you still have a black screen issue.
