From 5defbb5ff664f141293f800c486bc5b723f985ce 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. --- hwdb/70-pointingstick.hwdb | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'hwdb/70-pointingstick.hwdb') diff --git a/hwdb/70-pointingstick.hwdb b/hwdb/70-pointingstick.hwdb index 9fd5fb886a..e87d753339 100644 --- a/hwdb/70-pointingstick.hwdb +++ b/hwdb/70-pointingstick.hwdb @@ -41,6 +41,7 @@ # # Allowed properties are: # POINTINGSTICK_CONST_ACCEL +# POINTINGSTICK_SENSITIVITY # ######################################### # POINTINGSTICK_CONST_ACCEL # @@ -53,6 +54,17 @@ # by how much to multiply deltas generated by the pointingstick to get # normalized deltas. # +######################################### +# POINTINGSTICK_SENSITIVITY # +######################################### +# +# TPPS/2 IBM TrackPoint driver sensitivity sysfs setting +# POINTINGSTICK_SENSITIVITY= +# +# Where is a number between 0 and 255, note this property +# only applies to TPPS/2 IBM TrackPoint devices, see +# drivers/input/mouse/trackpoint.c in the Linux kernel sources. +# # # Sort by by brand, model -- cgit v1.2.3-54-g00ecf
