I currently own a Lenovo X60t (tablet) and am experimenting with putting linux on it. Here are a few random notes, tips, and tricks about the process.
I'm currently using Ubuntu.
I like the trackpoint sensitivity to be rather high so I don't have to put too much pressure on it to move it. To chance the sensitivity execute the following commands at a shell terminal:
$ sudo -s
$ echo -n 235 > /sys/devices/platform/i8042/serio1/input\:mouse1/device/sensitivity
$ echo -n 97 > /sys/devices/platform/i8042/serio1/input\:mouse1/device/speed
You can tweak the 235 and 97 as long as they're between 0 and 255. I'm not sure what the difference between sensitivity and speed is. Feel free to post it if you know.
