usb mouse vs touchpad speed

wetweasel · 11-25-2010, 02:53 AM

when using my touchpad the pointer is on a good way to reach the speed of light. while this could be considered progress physics-wise, it's impractical.

my usb mouse works just about fine.

why the difference? touchpad drivers? how can I modify mouse speed per device?

First, identify your touchpad.
It's probably connected via usb, so type as root (or not) :

Seems the touchpad is Bus 003 Device 004: ID 04f3:0230 Elan Microelectronics Corp.

What is your Linux distribution ?
Can you post the output of :
lsmod

not many, I have most of my drivers compiled into the kernel - I don't really get the great thing about lkms: "you can load them when you need them" - well, I always need them, especially something like HID drivers, so why would I compile them as modules?

The less you have inside the kernel, the better it is. Smaller, faster, "less bugs" etc...
And maybe you have to specify parameters to you module, so right now, the only way is to pass a kernel parameter at boot.
If the "elan" was built as a module, you could have simply unloaded it then reloaded with the parameter.
Anyway, you first have to determine which hardware you use.
