I'm the kind of person who wants a touchpad so good that I don't feel the urge to use a mouse, so maybe I'm just picky. But I really really really do notice the difference. With Greg's patch, I have to use a -0.75 accel value, and it feels perfect. But there may be hardware-specific factors at play. My touchpad hardware is definitely not the highest quality in the world. I'm not married to Greg's patch per se; my issue with libinput's default acceleration curve is pretty simple to articulate: it accelerates too much at slow and slow-medium speeds. Check out the graph attached at <a href="https://bugs.freedesktop.org/attachment.cgi?id=136584">https://bugs.freedesktop.org/attachment.cgi?id=136584</a>: Up to 50 mm/s, the default acceleration is faster than with Greg's patch, and there's a very abrupt cliff where the acceleration increases. Aside from technical matters, I'm just not sure what the justification is for accelerating small movements that much. It makes precise control very difficult. I do not have a HiDPI screen (didn't know it was directed at me, sorry). Regular old 1920x1080 @ 13". Not sure it's relevant now since I'm using KDE Plasma with KWin, not GNOME with Mutter.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
