Installed Teamviewer 13 on Ubuntu Mate 18.04. Having problems starting it. (On the host). It tries to start, shows the outline of a gui window temporarily, then closes. Of course, guest systems are not able to connect to it, either.
Well, I narrowed it down to a problem with the Nvidia driver. I reverted back to the Nouveau driver and Teamviewer now works well. Wish it would work with the Nvidia driver enabled, though.
OK, now I am confused. Today I’m using Nvidia drivers, and Teamviewer works again.
Wish I could tell you what happened and how, but I can’t.
Just glad it’s working.
