I need to use Teamviewer 7 to do remote support on my company, but when I try to connect to any host, the system just break everything and goes to the Login Screen. If I install 12.04 and then upgrade to 14.04, the error doesn't appear, but if I upgrade again to 16.04 or do a clean install of 16.04, the error appears again. Can anybody help me please? I think it's suposed to be the Xorg because the same error occurs on Ubuntu with Unity, Gnome, Mate, Xubuntu, Lubuntu, LightDM or GDM... I just don't tried Edubuntu or Kubuntu (don't like KDE). If I run Teamviewer for Windows from Wine, this error doesn't appear, but I'm migrating some Windows machines to Ubuntu, and Teamviewer for Windows doesn't allow to connect to it, just connect to another machines from it.
