teamviewer 12 on Ubuntu 16 Desktop extremely slow without display connected

Hi,

I have two identical computer running Ubuntu 16.04 Desktop, they runs Teamviewer 12.0.85001 and both have this issue: incoming connection is extremely slow. There are other computers in the same network, with Ubuntu 14.04 and teamviewer (same version) works without any problem, so it's not a network problem. All these computers run without a display physically connected.

Is there any issue related to teamviewer 12 on Ubuntu 16 instead of Ubuntu 14? I can I solve this issue is a software way (I'd avoid dummy plug o something like that).

Thank You

Solved !

I simply connected a HDMI->VGA adapter to the computer, that solved my problem. Now the resolution for the remote screen is bigger and not lag at all. Probabily a dummy plug is the best solution, as also suggested in teamviewer website for headless systems. Seems that some video card gives troubles to TW in headless mode while others don't, and this is not related to the OS version (in my case Ubuntu 14 was working while Ubuntu 16 don't)..

Have the exact same issue. Bootup with a display attached and no problems, but bootup the server without one and things get REEEEEAAAAALLLY slow. 

Any news, ideas or fixes related to this?

I find it hard to consider it solved. More like temporary workaround available until TV can fix this properly.

The tower I have just has vga out.  What would I need that would be equal to the hdmi to vga adaptor?

 

Thanks

I have a old Graphics card sitting around. I have just plugged it in to the pcie slot, without plugging in monitor and it seemed to solve the problem. I will do this until i get a hold of a headless display plug. However, this could be a solution if you don't have hdmi out, or don't have a headless plug.

Dave, You can use a VGA dummy plug, you can even build one yourself

Or you can use a software solution:

But the software solution won't let you use a real monitor, so it's not recommended in my opinion!
