I noticed that once I upgraded from Zorin 16.x to 17.2 now my Teamviewer (installed via Zorin SW Manager back in Zorin 16.x version) does not allow my mouse nor keyboard to interact with a GUI of a PC I am connected to (machine with Zorin OS) - whereas in 16.4 this was not a problem.
Now, after connecting, user at the other end has to allow my connection (I get it, this is because of security), but even if they do, I cannot move the mouse or interact in any way with their screen, keyboard included (this was not a problem back in Zorin 16.x).
I checked the settings, there doesn“t seem to be anything set in a wrong way.
I am connecting from Windows 10 Pro 64 bit -> Zorin, if it is of any relevance.
Does anybody know what should I do to enable interaction with the connected screen (i.e so my input via keyboard + mouse will be registered/reacted to)?
Haven't used teamviewer so much in the recent times, but did it upgrade versions while you went through the upgrade? It may also now have an option you have to enabled where you "allow remote connections to control the screen via mouse/keyboard" or something to that effect. I've run into it a couple times here and there, but it's been so long since I've dealt with teamviewer that I'm not sure what settings that has to choose from anymore.
I think this may be an issue due to Wayland, which is the new default window display manager starting in Zorin OS 17. Wayland is notorious for it being restrictive when sharing window access across programs, and remote sharing is one of the most iconic examples where it lacks the most.
You can quickly test this by switching to Xorg, instead. Logout of your account and use the wheel icon at the lower right corner, where you will have an option for "Zorin Desktop on Xorg", and try again.
That's really interesting, I don't use Teamviewer myself so I didn't know about the prompted options... I'll bookmark this answer as I suspect will come in handy in the future. Thanks for sharing!
The problem you found is not limited to any software or OS. When I was working, Head IT guy came to look at an issue on manager's PC. He quickly diagnosed the issue being PICNIC. Problem In Chair Not In Computer!
