Can someone please help me. I'm NOT a linux user and I find this OS VERY FRUSTRATING!!!
I tried to double click on the Displaylink driver file, it ran and then stopped after about 15 minutes. I tried to run it in terminal, but I get "Command Not Found"
here's the terminal results:
sudo ./displaylink-driver-5.3.1.34.run
sudo: ./displaylink-driver-5.3.1.34.run: command not found
Why is everything in this OS so damned difficult? Does MS own double click and a software gets installed? Jeeez
