I am trying to hide the mouse pointer via:

(setq x-pointer-shape x-pointer-invisible)
(setq x-sensitive-text-pointer-shape x-pointer-invisible)
(setq void-text-area-pointer 'text)
(set-mouse-color (cdr (assoc 'mouse-color (frame-parameters))))

The last command is supposed to make the previous changes effective (it works with other pointer shapes), but in the case of x-pointer-invisible I get the error can't set cursor shape: BadValue.

Any ideas on how to fix this, or another way to make the mouse pointer invisible? I am looking for temporary invisibility that can be toggled on the fly.

  • The error is produces by x_set_mouse_color in src/xfns.c:1282 and is an error that is returned by the X server after the function XCreateFontCursor is called, so outside of emacs control. I suspect that you either are doing it wrong or you cannot use this method at all, but that's all I can say: I don't know how to do it right or whether another method exists. Some searching uncovered this but AFAICT the situation is far from satisfactory.

  • A guess is that x-pointer-invisible isn't supported on your platform (or perhaps by Emacs?).

  • Thanks, @NickD and @Drew. For context, I have tried several x-pointer-* shapes and only x-pointer-invisible gives problems. I am on Linux/X11.

  • Maybe google to see if x-pointer-invisible is supported on GNU Linux/X11?
