Resize issues – Resolution is fixed and does not change

[juliusmeyer]

Hello,

I’m experiencing a frustrating issue with NoMachine (version 8.14.2) while trying to access my openSUSE Linux machine from my Mac (macOS 15). The main problem is that I cannot resize the remote screen, and it always displays only the upper left corner of the desktop. As a result, I am unable to view or interact with the rest of the screen properly.

Interestingly, this issue does not occur when I’m streaming from another Windows computer; resizing works perfectly in that scenario. It does not matter whether I chose “Enable viewport mode”, “Scale to window” or “Resize remote display”. Its always just the upper left corner (approx 1/4 of the screen). I tried changing resolution on my linux and my mac but it did not help.

In “Change settings” I cant use a custom resolution and everything seems very limited (see screenshot attached).

Has anyone experienced a similar problem or have any suggestions on how to fix this? I would greatly appreciate any help or insights you can provide!

Thank you!

Hi, please send us the output of xrandr command run in the remote desktop, and the logs from both sides. You can extract them using the instructions here: https://kb.nomachine.com/DT07S00243 (steps 1 through to 4). Send them to forum[at]nomachine[dot]com. Please use the title of this topic as the subject of your email. Thanks!

Your connection logs say that server uses resolution 3840×2160, and connecting client tries to change it to 1698×965 since the resize display mode is enabled. However the desktop turns it back again to 3840×2160 (this is up to the desktop environment) and the client is forced to enable the viewport mode, because the resolution is too big for the client display.

Can you confirm that, in this particular test, the reason why you see only part of the screen is not due to the client running in viewport mode? (i.e check whether the client is running or not running in viewport mode)

We also need to ask you for some additional information:

– Output of the command xrandr -q executed in a terminal window on the server

– We would like to try again to get server side logs. You don’t need to restart the
server after enabling the debug logging, just reproduce the issue and get a set
of logs:

1. sudo /etc/NX/nxserver --debug --enable all
2. Connect to the server, reproduce the issue and while the session is connected go to the next step
3. sudo /etc/NX/nxserver --debug --collect
4. sudo /etc/NX/nxserver --debug --disable all

Send everything as before 🙂

You could be encountering an already known issue,

Only a part of the desktop is rendered on 4k monitors scaled at 150%
https://www.nomachine.com/TR11T10690

Is there a scaling factor applied in the display settings of the server OS? The logs would help us to confirm that. You followed the instructions correctly, maybe try gathering the logs from outside the virtual environment?

From a terminal you can also try running tar -zcf nomachineLog.tar.gz /usr/NX/var/log and share with us nomachineLog.tar.gz.
