Hi,
I've recently installed Arch Linux on my new laptop (Toshiba A500). I'm pretty sure that the touchpad was working fine the other day in Arch, but something has gone wrong, and I have no idea what.
Whenever two fingers (or a wrist) touch the pad at the same time, the pointer goes insane. It moves all over the screen very quickly, and then the edge scrolling stops working. Edge scrolling works fine before the pad gets touched by two fingers at once. This is quite frustrating, as the position of the touchpad is right under my thumbs / wrists. (The pad is flush with the laptop, not sunken in).
Here is some output from synclient, if it is any help.

Does anyone know how to fix this?
Thanks.
Edit:
Hi. It seems to have come right overnight.
Thanks.

is a multi-touch touchpad? www.toshiba.com should tell
if it is, try force disabling it via synaptics

Hi,
Thanks for the quick reply. I'm pretty sure that this is a multitouch pad (In windows it had pinch and rotate etc).
I've disabled anything that uses more than one finger, but that doesn't seem to have made a difference.
Here is my configuration, if anyone can see something wrong with it.

Hmmm - you marked this thread as [SOLVED] without a hint what you did to solve it?
I have similar issues: If I put more than 1 finger on the trackpad, then the second touch does not get recognised. I can't even drag a window...
What was your solution?

That sounds different to what was happening to me. I was still able to tap and drag.
I can't think of what fixed the issue for me. I disabled anything that used more than one finger, and restarted. That didn't make a difference. I then shut down, and went to sleep. The next day, the touchpad was working fine. I'm not sure if the shutdown had any effect or not.
