I tried team viewer 13 on a couple of remote sessions from my Ubuntu 14.04 based system .
Connection to a windows system was fine, no issues.
I connected to a Linux Mint 17 system successfully and had multiple disconnects each one requiring a reboot to close the failed connection.
Installed on a Linux Mint 18.x system for remote access to that system, and it would never show the icon in lower right corner . When you ask to launch a program you should not then have to look for a small icon to actually open it! Tried reverting back to team viewer 11 and now it says the daemeon is not running.
I have spent (wasted) the better part of a day on team viewer today and mty time is worth something.
your forced upgrades cause more headaches than its worth.
I may be kissing team viewer goodbye keeping machines on same version across platforms is too challenging
