I've been looking for a Linux clipboard manager to use over SSH but they all error out with for example (on running SSH in Windows Warp to access a LAN Linux box):

     echo "doodah" | xclip -selection c
    Error: Can't open display: (null)

Here I am trying to copy to the X-11 clipboard in order to paste elsewhere inside the Linux box -- hope that's not too confusing!

Will your (eventual) clipboard manager work over SSH for this use case?

You can just connect to a running X session from an SSH shell; if your X server is on display :0 (usually the default), then you just

  export DISPLAY=:0
  echo foo | xclip -selection clipboard

This even can work with Wayland, where it becomes

  export WAYLAND_DISPLAY=wayland-1
  echo foo | wl-copy

(Note that AFAICT Wayland sessions number from 1 instead of 0)
