Does TeamViewer run on Linux?
Verdict: Yes
Yes. TeamViewer publishes an official Linux version, and it connects to Windows, Mac and phones exactly as the Windows one does.
TeamViewer has a Linux download on its own site, offered for Ubuntu and Debian systems among others. It is the same product with the same interface, and your account and computer list come across when you sign in.
Both directions work. You can sit at the Linux machine and take control of a Windows computer, and someone on Windows can connect in to help you with the Linux one. File transfer and chat work as before. This is one of the easier programs on the list to carry over.
Licensing is unchanged too. The free tier for personal use is still free, and a paid licence covers the Linux version the same as the Windows one. TeamViewer's habit of interrupting heavy free users with commercial-use warnings follows you across as well.
If you are helping family who are still on Windows, this is worth setting up before you wipe the old machine, so the computer list is already there when you sign in on the new one.
