Comment 9 for bug 278585

blue, I'm trying to reproduce the issue and gain as much info as possible for both before and after things start working. When investigating how to enable SHMConfig I hit on this link. Notice the sentence "Ubuntu 8.10 (Intrepid Ibex) and later completely rework how touchpads are configured and detected" near the top of the page. Late in the page it mentions "Note: In Ubuntu 8.10 (Intrepid Ibex) and later, tools such as xinput can alter touchpad settings without needing SHMConfig to be enabled." I suspect there's some bad math or an exception going on.

I will continue my efforts to get what you asked for.

Cheers
