Switching the view between multi-monitors in version 9

Hi Basstie and Serqetry, we have sent you a package to test. It contains a potential fix. So please install and let us know if the problem is solved. If you can still reproduce it, please submit the logs. Instructions are in my email. Thanks!

Hi Britgirl,
Thanks for sending me the package to test. I only just got the chance to try it out. Since there’s a newer version now, I updated to the latest (9.1.24) before testing. Everything’s working perfectly now. Thanks a lot!

Hi, thanks for coming back. It would have been useful to know if you can reproduce the problem with the test package – because to be honest, we did not include it in the 9.1 release (it was scheduled for the next maintenance) 🙂

Maybe something changed on your system since you first posted the problem, this might be the reason that you can no longer reproduce it?

Hello,

I installed the test dmg I was sent, but it didn’t make any difference.

From the Linux client when connected to the MacOS server, I get only one monitor available to choose… but it is showing both remote monitors, one shrunken down inside the other one.
There is no way to alter any settings, it is stuck on “Monitor 1”.

Hi @serqetry,

sorry for the late reply. Based on logs your problem seems to be different. Can you try using latest version of NoMachine? If that doesn’t help we’d like to send you a package with a potential workaround and more logs enabled.

I had a recent success with this. I’m connecting from an older mac running Catalina (10.15.7) to a laptop running Ubuntu (25.04). Both are running NoMachine 9.1.24.

I couldn’t switch displays when there were 2 large monitors and the laptop screen.  When I disabled the laptop screen and restarted NoMachine, switching displays worked properly.

Maybe it needs all monitors to be the same size??

Also, the ubuntu laptop was running Plasma Wayland window manager by default.  It worked for me only when I changed this to X11 at the login screen.  I chose Plasma X11.

Hi mikeg,

To allow us to investigate your problem, can you please send us the logs to forum[at]nomachine[dot]com, making sure to reference the topic as the subject of the email.

If needed, you can find instructions to collect logs here

It would also be useful to know exactly which monitor setup you use (e.g if any monitors are in mirror mode), and what you mean by unable to switch monitor? Do you see all the connected monitors when using Ctrl+Alt+A in player to select all the monitors?

[serqetry]

I tried the latest right now on both machines.  No change, dual monitors do not work.

I’d be happy to try the new test version.

Thank you.

Hi @serqetry,

Thank you for your patience — and apologies for the delay in getting back to you. We’ve been focused on recent fixes for macOS Tahoe, and I’d like to gather a bit more information to help investigate your case further.

Could you please let us know:

– The models of the monitors you are using.
– Whether any of them are Retina displays.
– If you are using any external applications to manage or alter screen resolutions.

Additionally, would you be open to testing a debug package so we can collect detailed logs and better understand what’s happening?
