Client resolution is higher then the server

[bugizozi]

Hi All,

I have a notebook with 1920×1080 resolution (KDE Neon 22.04, NoMachine server) and a Windows 11 PC with 2560×1080 resolution.

Is there a way to connect from the Windows PC to the Notebook via NoMachine with 2560×1080 resolution? I set up the fullscreen, but I can see only 1920×1080 resolution.

It works with Windows to Windows via RDP.

Thanks!

Can you show us the output of the xrandr command so we can check what resolutions are available to you?

When connected to the physical desktop, the maximum resolution you can get is the maximum resolution supported by the remote graphics card i.e the one on the Ubuntu host in your case. More about this is available here: https://kb.nomachine.com/AR02M00835.

You mentioned RDP which works that way because it is a virtual session. If you want to work with a virtual display with NoMachine and a higher resolution, you can try two things:

1) try launching NoMachine’s own framebuffer. So kill X (sudo init 3) and restart nxserver. NoMachine will create its own virtual framebuffer. You should be able to connect and change the resolution.

2) try the NoMachine Workstation. It’s available in the Enterprise section of the download area.

I had the same issue. I followed this advice:

1) try launching NoMachine’s own framebuffer. So kill X (sudo init 3) and restart nxserver. NoMachine will create its own virtual framebuffer. You should be able to connect and change the resolution.

That is a MILLION times better. Thank you.
