Scrolling with the mouse wheel doesn't work for me in emacs. When I try, I get the messages:

mouse-4 [[or mouse-5]] is undefined

I tried M-x mouse-wheel-mode, but get the error:

Symbol's value as variable is void: mouse-wheel-mode

Possibly useful information:

  • I recently installed Ubuntu 13.04, dual-booted with Windows 8 on my laptop.
  • I installed emacs using apt-get install emacs, which pulled version 23.4.1
  • I'm a fairly comfortable Linux user, but I have very little system management experience so it's entirely possible I'm missing something obvious.

Have you loaded library mwheel.el[c], where mouse-wheel-mode is defined?

  1. Make sure the library is in your load-path:

    (add-to-list 'load-path "/your/path/to/dir/where/mwheel.el/is/located/")

  2. Then load it:

    (require 'mwheel)

  • Thanks for the answer. I missed it when you replied. I actually fixed the problem myself recently. Only root had access to my .emacs.d directory; adding full access for everyone made emacs start behaving.

Dan hit it with the perms on .emacs.d - the current emacs package installer assigns root:root ownership and no user perms on that (empty) directory. Changing the ownership fixes the scroll wheel problem. I'd call that permissions issue a bug. I'd vote up the answer but it's in a comment - thanks, Dan!
