NoMachine to Sequoia – screen won’t wake

[Fritz]

NoMa 9.1.4.  Free.  MacOS 15.6.1 –  remote
Android v9.0.186 – client
having an issue logging in.  I get in no problem but the remote screen doesn’t wake up.

I have “wake for network access” on Mac sys settings, ticked.

And “make access available when still on login screen,” in NoMa, ticked.

I would assume this is a MacOS issue, but is there a workaround?

I’d send a log from the Pixel, but can’t access it at android/data/com.nomachine.nxplayer/files/

Hi,

are you referring to the actual real monitor (server-side) which remains asleep or do you mean that in the session window it stays blank?

A possible workaround is to change the DisplayServerExtraOptions key which changes the screen grabbing method. It’s in the node.cfg file on the Mac server host. Look for the DisplayServerExtraOptions “” , remove the prepending # and change it to this: DisplayServerExtraOptions “-nosckgrab”. Restart the NoMachine server. Then try to reproduce the issue again.

session window stays blank.  I’ll try that.  Thanks Britgirl.

where can the node.cfg file be found?  I don’t see it in sys or user library, NoMachine/Contents, App Support, Prefs, Containers

I just tried again after checking some NX related sys prefs and toggling.

Put the Mac to sleep. Logged-in with NoMachine.  Android screen (client) stays blank, but Mac remote screen opens, and I can see the cursor and move it from the Android.

Hello Fritz,

You can find the node.cfg file in /Applications/NoMachine.app/Contents/Frameworks/etc/node.cfg

node.cfg won’t take the edit/change

It’s probably because you have to edit it as a privileged user. Anyway, you can simply open a Terminal and paste this command there:

echo 'DisplayServerExtraOptions "-nosckgrab"' | sudo tee -a /Applications/NoMachine.app/Contents/Frameworks/etc/node.cfg

That will do the trick. Then you have to restart the NoMachine server with this command to apply the change:

sudo /etc/NX/nxserver --restart

Thanks fra81.  I’ll give that a go.  I always wanted to be privileged.

got negativity back. the ????? are mine, not Terminal.

It didn’t do it at 1st because there was a Security setting on the mac that needed a tick.  All good. Thanks,  I now see the screen on log in.
