[vim/vim] Clipboard and primary selection registers not working despite +clipboard (Issue #15111)
Enrico Maria De Angelis
Steps to reproduce
- The version of Vim reported below is installed on a Debian 12 system
- I connect to it via
ssh -Y user@host(same behavior forssh -X user@host) yanking in+or*registers is not effective, norputting in them; indeed, after I attemptedyaking in them, they're still not listed in:registers.
Expected behaviour
If I run xterm-256color in a GUI session on the host, + and * work. Indeed, when I'm in the office they do work.
And if I connect via SSH from a xterm-256color on my computer, + and * don't work.
So I think the problem is unrelated to the terminal emulator, but to SSH. Indeed, I would have expected the observed behavior if I had not passed -X nor -Y.
Version of Vim
9.0 (2022 Jun 28, compiled May 04 2023 10:24:44) Included patches: 1-1378, 1499
Environment
- Operating system: Debian 12
- Terminal: what is this?
- Value of $TERM:
rxvt-unicode-256color, but I've tried withxterm-256color, and obeserve the same behavior - Shell:
bash
IMPORTANT I'm connecting to the machine via SSH, so the value of $TERM is the one on my system (Arch), not on Debian 12.

@nv-quan , I think it doesn't
- I'm not on a Mac
- I know I don't need any mouse-settings different that what I already have, considering that the clipboard does work on a Debian 11 I still have access to (I'll copy more detail from the stackexchange question to here, sorry)
- I am already using
ssh -Xas suggested by the last bullet point in the accepted answer.

Then could it be a X-forwarding issue? Did you try copying to clipboard using another app through the ssh x-forwarding?

Would you suggest a way to use the clipboard via SSH that doesn't involve Vim?

Maybe you can try xclip

I worked from the office today, so I could try this:
- open a terminal emulator
- select some text with the mouse
- execute
xclip -o - SSH to oneself (with
-X) - execute
xclip -o
At step 3, the selected text is correcly echoed.
At step 5, I get
Error: Can't open display: (null)

Ok, nevermind, it turns out IT department had disabled X11 forwarding :|
The solution was to add a whatever.conf file under /etc/ssh/sshd_config.d/ with content
X11Forwarding yes
which has clearly nothing to do with Vim.
I suppose this thread can be closed, ... unless Vim could have a way to test for such a lack of x11 forwarding and throw a warning/error?
If not, I guess we can truly close this.
