[ltp] "ThinkPad USB Keyboard with TrackPoint" in Linux?

Sat, 03 Jul 2010 12:26:34 +0100

I've got one. It works really well.

The only problem is that I haven't figured out a way to alter the 
default trackpoint sensitivity (I'd prefer to increase it).

If you just plug it in, it will work. However, you may wish to be clever
with xorg settings.

If you set up some udev rules such as below, you can then set Xorg.conf 
rules for each mouse-device. So for example, you might want 
emulated-scroll + emulated middle-click on the trackpoint, while setting 
the track-pad to disabled. You might also have different rules for an 
external mouse.

#Here are my rules, on mandriva 2009.0. Your specific values may differ.

#First, identify the devices. cat /dev/input/mouseX and cat 
/dev/input/eventX while moving the devices
#Second, find a relevant udev rule. Pick one stanza only for 
identification. udevinfo -a -n /dev/input/mouseX
#Third, write the rule here. Remember use "==" to match attributes, and 
"=" to define attributes.
#Fourth: run   udevcontrol reload_rules; udevtrigger to make it update, 
then test.  (if inotify is enabled, the udevcontrol reload_rules may be 
omitted)
#Fifth, use the symlink in xorg.conf
#See http://reactivated.net/writing_udev_rules.html for an excellent 
explanation of udev rules

#Be careful: the touchpad and trackpoint have very similar attributes.
