That indeed changes the speed, thanks! However, please let me ask again: Isn’t the sysfs interface supposed to work, too? I’ve got my problem resolved for Xorg now, but about every article on the internet refers to the sysfs interface for changing the speed, cf. <https://www.google.com/search?q=trackpoint+speed>. I’m also fine with the assertion that Lenovo shipped a broken firmware, but I’d expect some warning in dmesg then and a reasonable fallback (to a regular PS/2 mouse?) then. Can we at least agree that there is a driver bug that ought to be fixed or a firmware bug that ought to be worked around?
