Ubuntu 18.04 LTS and hdmi connection

[Dietmar]

Hello Ubuntu-friends,

Maybe I write in English as either I know you nor your language used 
normally.

I would like to explain my problem with a hdmi-connection to our SAMSUNG TV.

We want to connect my Laptop to our tv.   After having succeeded to 
install the  cyberghost vpn on my Ubuntu 18.04 system,  we can now 
neutralize geo-blocking of french television f.ex.

Unfortunately SAMSUNG blocks the connection from my smartphone by use of 
the "Smart Thing" App once I activated the cyberghost on my smartphone.  
That's the reason why I try to connect our tv with my laptop (via usb cable)

As I have installed Ubuntu 18.04 LTS and windows 10 on my Laptop 
(dual-boot) I tried the hdmi connection which worked without any problem 
with windows 10 (except that windows 10 is very slow on my ASUS D553S) 
and I prefer working with Ubuntu.

I use Ubuntu for 99% of my daily tasks.  So I would like to resolve the 
problem for the hdmi connection un my Ubuntu operating system.

When I connect the hdmi cable with my laptop nothing happens and the 
screen of my laptop turns on black display.

The SAMSUNG tv does not recognize the external source.

So, I made some investigations in the internet and detected some 
commands concerning the controller.

Unfortunately my laptop does not use a NVIDIA, but the following 
integrated VGA controller:

lspci -v | perl -ne '/VGA/../^$/ and /VGA|Kern|3D|Display/ and print'


  hwinfo --gfxcard --short

So my question:  Did you have already experience with hdmi-connections 
to tv?

If yes, any idea how I can resolve my problem?

I'm not an UBUNTU specialist, but I'm a great supporter of this 
operating system.

Best regards,

Dietmar Schumacher
