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
@markosjal, if you don't have a tray icon, then (most likely) either your desktop environment does not support them or TeamViewer could not start successfully.
If TeamViewer is started automatically on login, it is started in the background (like all well-behaving applications do). If you start it manually from the menu, it should always start in the foreground, or come to the foreground if it was already running.
After installing [Update: 13.0.9865] File Transfer & Chat, if you still experience these problems, I need more data to get them fixed for the March release. Name your desktop environment and the exact steps how you start TeamViewer and what happens then.
