Hi Thanks for you reply !!, if I want to copy from any place to any other place a text, lets say from a web page that I open in chrome, I choose the text inside the web page then I do ctr+c or right click with the mouse and click on copy, then I go to my text file and press ctr+v or mouse right click paste, but nothing is copied. I am using Fedora gnome -Xorg. I could not pass an interview because I wrote my code in IntelliJ then I could not paste in the web page of the code interview or in an email !!! It never worked copying and pasted from a text file to the ssh terminal, but now It does not work at all. any help is welcome !! thanks again !!
