I’m afraid I haven’t. But it’s still occurring from time to time. It’s definitely some process “stealing” the “ctrl+” input and not releasing it.

Workaround is to close the NoMachine window (not session, for a clue) and reconnect. Since I have a workaround I can live with the bug. However YMMV.

# /usr/NX/bin/nxserver --userlist

All was making sense until I tried this, and got :

-bash: /usr/NX/bin/nxserver: No such file or directory

So I’m going to have to cram up on “How Macs work” and get back to you.

[Jethro_uk]

Many thanks for replying – and it seems you have nailed it 🙂

1) For some reason my server.cfg had CreateDisplay
set to “1”. I changed this. Then issuing the nxserver –restart command threw up an error:

NX> 162 Disabled service: nxserver.
NX> 162 Service: nxnode already disabled.
NX> 162 Disabled service: nxd.
NX> 111 New connections to NoMachine server are enabled.
NX> 161 Enabled service: nxserver.
NX> 162 WARNING: Cannot find X servers running on this machine.
NX> 162 WARNING: A new virtual display will be created on demand.
NX> 161 Enabled service: nxd.

AHA ! – So there really was no XServer running. For my particular machine, running:

 

sudo service lightdm restart

 

seemed to do the trick. The nxserver –restart then seemed happy. And connecting to the machine, I got the login window I used to get.

 

Case closed !

Update:

One thing that has also started happening which never used to, is I am getting a message:

“Cannot detect any display running. Do you want NoMachine to create a new display and proceed to connect to the desktop?”

 

Something has definitely changed and it happened Friday 17th May between 15:00 and 17:00 (when I rebooted).

How can I tell ??
