Evil emacs use `dd` change buffer and paste with `p`?

Question

I'm running evil emacs in terminal mode.

I have two files open in buffers I'm switching between with c-x, left/right.

I cut a line of text with dd then switch to another buffer and try to paste with p but I just paste some old text that I copied and pasted with right click earlier.

How can I move text like this when switching between buffers?

It sounds like you're pasting the contents of your primary selection rather than the clipboard. To check this you can watch the contents of your clipboards using xsel e.g. watch xsel -o -p (-p, -s, or -b flags for primary, secondary, and clipboard respectively).

Some possibly relevant stuff from the emacs wiki https://www.emacswiki.org/emacs/CopyAndPaste#toc2

X11 Copy & Paste to/from Emacs:

X copy and paste support has historically been a mess. This is relevant, as Emacs supports the various aspects of this mess.

Important for this discussion is the understanding that X generally distinguishes between two types of selection, the PRIMARY and the CLIPBOARD. Every time you select a piece of text with the mouse, the selected text is set as the PRIMARY selection. Using the copy function will place the selected text into the CLIPBOARD. Pasting using the middle mouse button will insert the PRIMARY selection, pasting using the paste function will insert the CLIPBOARD.

With this out of the way, starting with Emacs 24.1, GNU Emacs should already do the right thing here. If you dislike this behavior, there are two options you can customize:

x-select-enable-primary - default nil; set this to t if you want the Emacs commands C-w and C-y to use the primary selection.

x-select-enable-clipboard - default t; set this to nil if you want the Emacs commands C-w and C-y to use the clipboard selection.

Yes, you can have Emacs use both at the same time.
