            Bug ID: 94953
           Summary: libinput api should be changed to allow window
                    managers/desktop environments to specify higher mouse
                    speeds
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libinput
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: jonasthiem at googlemail.com

Let me first say I have no idea of the internal libinput API and I'm only
filing this because apparently there seems to be an inherent limitation that
prevents the GNOME developers from doing anything about this:

libinput api should be changed to allow window managers/desktop environments to
specify higher mouse speeds. Basically, I like somewhat obscene mouse speeds
which I understand are beyond what a usual user might be using since I prefer
to use my input devices precisely rather than make huge movements.

On all Thinkpad laptops (3 entirely different models) I have seen the highest
trackpoint mouse device sensitivity possible in Linux/GNOME is below what I
find preferable, with varying degrees of uncomfortableness. Also, most low-dpi
cheaper mouses move way too slow for my likings even at maximum speed (tested a
logitech, acer and another vendor I forgot).

However, the GNOME developers say they cannot even provide a hidden(!) option
somewhere in gconf/dconf for a multiplier to speed up the mouse speed like 2x
or even 3x times in overall, since the libinput API clamps at some arbitrary
1.0 speed limit which is exactly the not-very-fast maximum available using the
slider in the GNOME mouse settings.

The corresponding bug report on the GNOME bugtracker is here:

https://bugzilla.gnome.org/show_bug.cgi?id=762889

It would be nice if you could somehow figure out together how to make at least
implementation of advanced/hidden mouse settings in linux desktops possible
that allow users to specify a notably higher mouse speed than the arbitrary 1.0
choice without going as far as editing the hardware database file manually or
things like that.
