            Bug ID: 96225
           Summary: Logitech M500 behavior
           Product: Wayland
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)

          Severity: normal

Hello,

I have a Logitech M500 mouse and I find it not really pleasant to use on Fedora
23 with libinput 1.2.4 in comparaison to Netrunner 14.2 (based on Kubuntu 14.04
with synaptics driver I guess and updated with latest KDE 4).

On Netrunner I use these (default I think) settings in the mouse settings and
it's perfect :

Pointer Acceleration: 2x
Pointer Threshold: 4 pixels

On Fedora the cursor is too slow both for small or large mouvements by default.
If I increase the pointer speed in the mouse settings I can't obtain the same
behavior. Depending on how much I increase the speed the pointer can be too
slow for small and large movements or too slow for small movements and too fast
for large one or almost ok for small movements and far too fast for large one.

Is it something that can be improved in libinput or do I have to make some
custom config ?

Thanks !
