Someone with Teamviewer 12?

[kdemeoz]

Hi wonder, how are you? Yes i also have used TV for years, & also recently upgraded 11 to 12. The problem you're experiencing might be due to the TV daemon not starting [some previous TV versions also had this annoying problem]. See if this helps you.

1. In Konsole now, do sudo teamviewer --daemon start ... then retry your TV connection.
2, In Maui's Settings, Startup & Shutdown, Autostart ... create new entry "sudo teamviewer --daemon start".

Fingers crossed!
