From a1566e3492ae0f62901349c746421676630de1e4 Mon Sep 17 00:00:00 2001 From: Dmitry Maluka Date: Thu, 26 Aug 2021 23:06:30 +0200 Subject: [PATCH] quirks: Thinkpad T470 trackpoint multiplier Set multiplier for T470 to 0.4, same as for T480. Trackpoint behavior on T470 was good before 1.9.0 (more precisely, before the commit 87b568) when a new trackpoint acceleration algorithm was introduced instead of the traditional linear filter. Since then it is too sensitive and seems impossible to fine-tune using hw settings or libinput accel speed setting. With multiplier set to 0.4 it is as good (or better) as in 1.8.4. Sensitivity feels the same as in 1.8.4 with the same hw settings for speed and sensitivity.
