clipboard: error invoking xclip: Error: Can't open display: 172.19.176.1:0

After pressing the "" key I have about 1 minute of nothing happening. Then I get a message

clipboard: error invoking xclip: Error: Can't open display: 172.19.176.1:0

and peekup window is open.

The error is presumably due to xclip: are you by any chance redirecting the vim registers or vim yanks to xclip?

In order to identify the problem I would suggest to:

• show the output of :echo getreg("*") (which is the unnamed register)
• show the output of set clipboard?
• yank some text and then try to execute "": do you still see the error?

Moreover does the output of the command :registers show fine?

What system are you on and does it happen also if you deactivate xclip altogether?

@gennaro-tedesco
:echo getreg("*") gives me fed8bd897e410cc34b2734e142882028
clipboard is clipboard=
yanking text doesn't change abything.
:registers also have this lag and also show me error message.

I'm on Ubuntu 20.04 WSL, don't use xclip explicitly but I have $DISPLAY env variable.
If I unset it everything works fine.

:registers also have this lag and also show me error message.

this means that the error is not generated by the plugin, rather by vim loading the registers content. Looking around I have found this and this, which may shed some light on why $DISPLAY generates such error.

What happens if you set clipboard+=unnamed in your vim configurations?

[horseinthesky]

With set clipboard+=unnamed the issue is still there.

Actually, I can just get rid of $DISPLAY since I don't use it right now.
Just want to understand what is going on.
Please correct me:

1. :h clipboard says NVIM is using xclip if there is $DISPLAY env variable.
2. xclip is supposed to be connected to some x11 server.
3. If there is no x11 server that ~1 min interval is some sort of timeout interval for this connection?

[gennaro-tedesco]

I believe what you are saying is correct however I am not an expert on this, so don't take my word for granted. Ideally one could test if any other process involving xclip --> x11 works correctly without lag, but I wouldn't really know what to look into, in that direction.

[horseinthesky]

Ok. Thank you.
