Where are the config files stored for the mouse trackpoint? My resolution is terrible and I want to see if I can improve it. The mouse pointer seems to jump 3-4 pixels at a time and not glide smoothly across the screen. It makes pointing and clicking on things a little difficult.
I have a Thinkpad X60s which uses the trackpoint nipple between the keys as opposed to a touchpad.
Ok, I resolved the problem. It was something quite basic in the end and was a misinterpretation of one of the settings.
In the Mouse preference setting GUI there is a slider for sensitivity. I understood this to be how sensitive you wanted the trackpoint to be, i.e. less or more fingure pressure to move it. It turns out that yes, while it does affect the sensitivity it also messes up the resolution, so low sensitivity=less pressure required but low resolution; high sensitivity=more pressure required but high resolution.
I found this a bit strange in that it affects both parameters. Is there a way of just adjusting the pressure sensitivity on the trackpoint as I prefer a light feel?
UPDATE
For those who may be interested. I found out how to change the sensitivity (how hard you need to push the nipple) of the trackpoint.
Issue this command where 180 is a value between 0-250 (higher number more sensitive):
Speed is adjusted with # echo -n 90 > /sys/devices/platform/i8042/serio1/speed
Not the above is for Thinkpads with trackpoints only, if you have a trackpoint and touchpad then the path is a little different.
