From c17bf408252681edd095ba9e2c38d0caf3c386ba Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 17 Apr 2015 16:48:07 +0200 Subject: udev: keyboard-builtin: Add support for setting IBM trackpoint sensitivity IBM / Lenovo trackpoints allow specifying a sensitivity setting through a ps/2 command, which changes the range of the deltas sent when using the trackpoint. On some models with normal usage only deltas of 1 or 2 are send, resulting in there only being 2 mouse cursor movement speeds, rather than the expected fluid scale. Changing the sensitivity to a higher level than the bootup default fixes this. This commit adds support for setting a POINTINGSTICK_SENSITIVITY value in hwdb to allow changing the sensitivity on boot through udev / hwdb. Signed-off-by: Anthony G.
