I installed Ubuntu on my new laptop and I need to connect it to a Samsung LED TV.

When I was in Windows 10 I was able to connect to my TV by just pressing the combination of Windows+K. Then it would automatically connect to it. I can't connect now.

• Dell Inspiron 15 3552


• Ubuntu 16.04 LTS

For the wireless projection You will need miraclecast to cast your screen over using the wireless display technology. To install miracle cast in Ubuntu via PPA:

sudo add-apt-repository ppa:thopiekar/miraclecast
sudo apt update
sudo apt install miraclecast ubuntu-restricted-extras check

To start casting

1. 
   

   Shutdown wpa_supplicant and NetworkManager:

   
   
   

   sudo killall wpa_supplicant && sudo service network-manager stop
   

   
   


2. 
   

   Launch wifi daemon:

   
   
   

   sudo miracle-wifid &
   

   
   
   

   Now run miraclecast as a peer (peer is your device that is casting its screen to the TV):

   
   


3. 
   

   Launch wifi control:

   
   
   

   sudo miracle-wifictl
   

   
   
   

   this should give you the miraclecast CLI and a link number. select the link with select link

   
   



4. Enable wifi-direct visibility on the other device (if possible)



5. 
   

   From the CLI locate the TV using:

   
   
   

   p2p-scan
   

   
   
   

   you get something like

   
   
   

   12:34:ab:cd:45:43.
   

   
   
   

   ie the mac address

   
   
   

   Then from the CLI initiate connection:

   
   
   

   connect <mac addr> [pin] 
   

   
   
   

   the pin could be the pin of the tv
