I'm following this tutorial to ajust the TrackPoint speed for my Lenovo T420. However, setting a value in /sys/devices/platform/i8042/serio1/serio2/speed has no effect.

The trackpoint is unaffected and cating the file after executing the echo -n shows the old value.

By the way I'm running Fedora 15, with kernel id –  Olivier Toupin Jun 18 '11 at 17:34
