Mint22 remote desktop unresponsive

[FumbleFingers]

In the past I’ve been able to connect from my mint pc “rambo” to my brother mike’s mint pc “newby” using NoMachine and actually control newby using rambo’s mouse and keyboard. We’re 200 miles apart, but both machines are on my Zerotier private network, and I seem to have full control when I log in via ssh (as user “mike”; we both have our own name as the only defined user on our machine). Now, although I can VIEW the newby screen, I can’t interact with it.

I’ve spent over an hour with chatgpt and got nowhere. Among other things, it had me edit the config file…
sudo nano /usr/NX/etc/server.cfg
…to add these lines…
PhysicalDesktopMode 1
EnableAdminAccess 1
EnableUserInput 1

…besides that edit, chatgpt had me try various other things, each followed by…
sudo /usr/NX/bin/nxserver --restart

…after which I would reconnect to the newby GUIthru NoMachine, but nothing worked.

Chatgpt agrees with my suspicion that remote desktop interactive access worked when we were both running Mint 21, and that it’s the upgrade to Mint 22 that’s causing the problem. My reason for thinking this is that under Mint21 we both used xbind to remap the otherwise-unused “back” mouse key to emulate typing our Linux password followed by <Enter>. That method stopped working after upgrading to Mint22, when we had to switch to using the input-remapper utility instead. This NoMachine problem looks like another manifestation of the same underlying security enhancement that prevents “untrusted” xbind emulated input being used in this way.

Hi, is there a monitor attached to the Linux Mint machine you are connecting to?

Is the image of the desktop you see totally frozen? Or do you see some screen changes when you are connected?

Logs would be useful. On the Newby machine, enable debug and try to reproduce. Please follow the instructions here: https://kb.nomachine.com/DT07S00243

Send them to forum[at]nomachine[dot]com or attach here. Please use the title of this topic as the subject of your email. Thanks!
