vim：更改显示编号

Question

How do I tell tell vim to use a non-default display number. The searches I've done so far just show me line numbers, which is not what I want. The xserver crashed and restarted, so I'm not on the default display, but instead am on :2. I would have assumed it would be something like :set display=:2 , but that is not the case.

Answer 1

Check that the terminal the vim was invoked from has the correct value in the DISPLAY environment variable and restart vim. Vim will use the display number from that variable.

I don't see a way of changing the display without restarting vim and will accept that over this current answer.
