Teamviewer 15

Post by REG » 2020/03/04 07:46:31

Hello, I am trying to install Teamviewer 15. When my Server is in graphical.target, everything works OK. When I change it to multi-user.target, Teamviewer will not start, even though the daemon is running. The answer I got from Teamviewer is:

The whole thing only occurs if no monitor is emulated via X. In this case, TeamViewer has no way of tapping the image and remains at "Initialize display parameters".

When I logged in and started startx, it still didn't work. I get a connection, but no Picture.
I am not sure what I need to do or check. Can anybody help me?

What stops you from bypassing it altogether and using ssh X forwarding like everyone else?

That's hard to do when I am 100 miles away.

I wasn't aware that ssh had a distance constraint...

OK, how can I tell if the Frame Buffer is installed and working?
How can I set up x-terminal-Emulator?
I tried for the last week to Google this, but never found a direct answer.

You run X on your local machine, you ssh -X to the target and make sure that the xorg-xauth package is installed on the target then reconnect if it wasn't and check that echo $DISPLAY says something like locahost:10.0 and then whatever X app you invoke sends its display over ssh to your local desktop. If you run windows then there are Windows X implementations that can be installed.

The forwarded X11 tends to be sluggish.

A faster alternative is NoMachine's protocol. The desktop is on the remote host and mere screenshots are passed over the network.
(I presume that the TeamViewer horror show is similar.)

Alas, NoMachine is commercial. However, there is X2Go.

x2goserver is in EPEL. X2Go has Windows and OS X clients too.

Oh sorry, forgot again.

You have to set up “sudo” so that a user can execute “systemctl isolate graphical.target”. Now a user can log in and then click on the user and GUI starts with teamviewer. To go back, "systemctl isolate multi-user.target" must be entered with sudo.
