Ubuntu 18.04 system freezes after plubing in display link docking station
 

Hello,

I am running Ubuntu 18.04 64bit system and after install when I connect the docking station to my laptop the system freezes. The mouse can move however no input and cannot user terminal. I have to reboot to regain control.

The install said everything was installed. I followed the instructions and only one thing to note from the install steps was that when I tried "Sudo apt-get install linux-signed-generic-lts-utopic the terminal window returned cannot find file.

I did a search on here however did not find a solution. Can anyone assist?
