# This file is part of systemd. # # Pointingstick const-accel configuration, to make different brand / model # laptop pointingsticks have the same speed / feel, and per model adjustment # of the IBM TrackPoint driver's sensitivity setting # # The lookup keys are composed in: # 60-evdev.rules # # Note: The format of the "evdev:" prefix match key is a contract between the # rules file and the hardware data, it might change in later revisions to # support more or better matches, it is not necessarily a stable ABI. # # Supported hardware matches are: # - Generic input devices match: # evdev:input:bZZZZvYYYYpXXXXeWWWW-VVVV # This matches on the kernel modalias of the input-device, mainly: # ZZZZ is the bus-id (see /usr/include/linux/input.h BUS_*), YYYY, XXXX and # WWW are the 4-digit hex uppercase vendor, product and version ID and VVVV # is an arbitrary length input-modalias describing the device capabilities. # # - Input driver device name and DMI data match: # evdev:name:<input device name>:dmi:bvn*:bvr*:bd*:svn<vendor>:pn* # <input device name> is the name device specified by the driver, # <vendor> is the firmware-provided string from the kernel DMI modalias. # # To add local entries, create a new file # /etc/udev/hwdb.d/71-pointingstick-local.hwdb # and add your rules there. To load the new rules execute (as root): # udevadm hwdb --update # udevadm trigger /dev/input/eventXX # where /dev/input/eventXX is the pointingstick in question. If in # doubt, simply use /dev/input/event* to reload all input rules. # # If your changes are generally applicable, open a bug report on # http://bugs.freedesktop.org/enter_bug.cgi?product=systemd # and include your new rules, a description of the device, and the # output of # udevadm info /dev/input/eventXX # (or /dev/input/event*). # # Allowed properties are: # POINTINGSTICK_CONST_ACCEL # POINTINGSTICK_SENSITIVITY # ######################################### # POINTINGSTICK_CONST_ACCEL # ######################################### # # Trackpoint const accel settings are specified as # POINTINGSTICK_CONST_ACCEL=<accel> # # Where <accel> is a floating point number, using a '.' seperator, specifying # 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=<sensitivity> # # Where <sensitivity> 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 ######################################### # Dell ######################################### # Latitude D620 evdev:name:*DualPoint Stick:dmi:bvn*:bvr*:bd*:svnDellInc.:pnLatitudeD620*:pvr* POINTINGSTICK_CONST_ACCEL=0.5 # Latitude E6400 evdev:name:*DualPoint Stick:dmi:bvn*:bvr*:bd*:svnDellInc.:pnLatitudeE6400*:pvr* POINTINGSTICK_CONST_ACCEL=1.5 ######################################### # Lenovo ######################################### # Lenovo Thinkpad X200s / X201s # Note these come with 2 revisions of keyboard, with the trackpoints having a # different sensitivity in the different revisions. 1.25 is a bit slow for the # least sensitive revision, but it is better to be a bit slow than too fast. evdev:name:TPPS/2 IBM TrackPoint:dmi:bvn*:bvr*:bd*:svnLENOVO:pn*:pvrThinkPadX20?s:* POINTINGSTICK_SENSITIVITY=200 POINTINGSTICK_CONST_ACCEL=1.25 # Lenovo Thinkpad T440s evdev:name:TPPS/2 IBM TrackPoint:dmi:bvn*:bvr*:bd*:svnLENOVO:pn*:pvrThinkPadT440s:* POINTINGSTICK_SENSITIVITY=200 POINTINGSTICK_CONST_ACCEL=1.0
