TeamViewer is a popular application for remote control, desktop sharing, file transfer, online meetings and more, that's available for Windows, Mac OSX, Linux, Android and iPhone.
The latest TeamViewer 8 (stable) for Windows was released back in December and today, the stable version is also available for Linux. While in beta, there were two bugs that affected for many users (myself included) until recently, which resulted either an "TeamViewer Daemon is not running. Please start teamviewerd and then restart TeamViewer" error message or a ghost window showing up.
But these issues seem fixed and TeamViewer 8 for Linux has worked properly in my tests under Ubuntu 13.04, 12.10 and 12.04. I'm not sure if these issues were present in other Linux distributions and if they were fixed or not.
