Client screen not refresh on mint 22.1

[silviomg]

I have two PC with Linux Mint. One has “Mint 22.1 Cinnamon” the other “Mint 21.3 Cinnamon”.

When I operate from 21.3 on 22.1 I see what I do and the screen 21.3 reflect the 22.1 screen. When I operate from 22.1 on 21.3 I don’t see any change on screen 22.1 bat command are executed on 21.3.

Both PC have the last version of NoMachine 8.16.1

Why that?

This has been reported a couple of times but we have never been able to reproduce it. It could be that your xorg is crashing. You should send us the full logs (debug enabled) as per the instructions here:

Forgot to ask, please also tell us if either of your Linux systems are running in a VM.

The logs were not from the server unfortunately which is what we need in this case.

First, please try disabling hardware decoding on the computer you are connecting from when you encounter this issue. The instructions on how to do that are here: https://kb.nomachine.com/AR07U01202 but I will paste them here for convenience.

Exit the Player by going to the !M icon in the system tray and selecting “Quit NoMachine player”.

Edit the player.cfg file in the user’s home on the client side.

This file is:
$HOME/.nx/config/player.cfg on Linux and macOS and %USERPROFILE%\.nx\config\player.cfg on Windows.

Edit the “Enable hardware accelerated decoding” key and set the value to ‘disabled’.

For example:

<option key="Enable hardware accelerated decoding" value="disabled" />

Then open NoMachine again and connect to the problematic Linux host. Is there any change?

If that does not help, then we will require the full logs from the problematic server side with debug enabled. If I’ve understand you correctly, this is the Linux Mint 21.3 host.  You can extract them using the automatic procedure here: https://kb.nomachine.com/DT07S00243.
