I am using this screen version on arch linux.

$ screen --version
Screen version 4.05.00 (GNU) 10-Dec-16

I am using the following screenrc commands to integrate xsel with gnome 3.22 for copy&paste to/from the clipboard.

bindkey -m y eval 'stuff \040' 'writebuf' "exec sh -c 'xsel -bi </tmp/screen-exchange'"
bind p exec setsid sh -c 'xsel -bo >/tmp/screen-exchange; screen -X eval readbuf "paste ."'

For the second line, I had to use "setsid" in the exec line in order for the paste to work.

Without setsid, the paste command will paste the content to the current screen window, however, the pasted string appears to be not really inserted to the stdin of the receiving process. I.e. the string will appear on the screen, but bash or vi doesn't see to receive it. If I press enter after the paste command with bash, bash acts as if no input is received.

If I paste the content into vi and then save the file, the file size is 0.

Only after the "setsid" change, I can make the pasting work.
