Before you go marking this as a dupe, I know about Ctrl+Shift+C and Ctrl+Shift+V
I try to use them, and it doesn't work. On one particular Ubuntu computer, normal copy paste commands do not work: They do not work locally, and they do not work via remote session.
My guess was that perhaps logging into a computer where these functions where acting normally, and logging in via ssh would bypass the issue. This was not the case. I still cannot gain this functionally, even though the Ubuntu PC I am using has functional copy and paste from the terminal.
So I am out of guesses.
How do I enable this? The affected computer runs Ubuntu MATE 16.04. The terminal is mate-terminal, except when I login via ssh, in which case it's Bash. Caja is the window manager.
