    I’m connecting from Windows 10 to Ubuntu 22.04.2. NoMachine version 8.4.2. All updates have been installed. I’m using a wireless Logitech mouse with the Logitech G Hub installed on Windows. After logging into the Ubuntu computer, I can not use the scroll wheel while moving the mouse. If I keep the mouse perfectly still, scrolling works fine. I haven’t been able to find a solution. Any suggestions?

    Are you able to test with a different mouse? Does that work without issues?

    It would be useful to see the xev output. Start the ‘xev’ utility on the Ubuntu machine and show us the output when you reproduce the problem with the mouse.

    Well, I was able to find something weird. If I connect via NoMachine remotely from Windows then log in to Ubuntu from the client, the move and scroll at same time does not work. If I connect via NoMachine but don’t log in, then flip my monitor over to the Ubuntu box and log in from there, then it works. It even works if I flip back and use the client afterwards. So it has something to do with the login to Ubuntu via the NoMachine client.

    Hi,

    It would still be useful to see the xev output from the Ubuntu machine (see my earlier reply).

    If you login to the desktop through the NoMachine session and then you flip the monitor over to the server, do you reproduce the same behaviour using the mouse attached to the server?

    Thanks for helping. Sorry I forgot to include the xev output.

    Here is the xev output when it is working:

    Move mouse inside or outside the box:

    Switching between monitor outputs doesn’t seem to be doing anything anymore so it must have been something else I was doing. I never had the mouse plugged into the server. I think it was just showing the movement through the NoMachine client. I can’t replicate the steps for it to be working again anymore.

    We were not able to able to reproduce the problem. If the issue returns, please grab the xev output and submit.  You can always open a new topic if this one is closed.
