Imagine my surprise when the usual X selection and clipboard techniques disappeared.
Normal behavior: - X11 - xterm or urxvt or gnome-terminal or whatever - copy text by selecting with mouse button 1 - move over to some other text input field and paste with button 3 except, vim stopped allowing the paste. Here's the change: /usr/share/vim/vim80/defaults.vim now contains: " In many terminal emulators the mouse works just fine. By enabling it you " can position the cursor, Visually select and scroll with the mouse. if has('mouse') set mouse=a endif That's nice. It doesn't actually work for the X cut and paste mechanism that I rely on, and it turns out that adding this to my .vimrc: set mouse=off or set mouse="" does not work. Instead you need to go to that defaults file and comment out the offending stanza. Use " as your beginning of line comment character. -dsr-
