Bug Description

While working with Ubuntu, touchpad stops responding. Here's the syslog happenings:

rmmod/modprobe cures it, but it's very unhandy.

It's Dapper Flight nr. 5 up-to-date. Dell Latitude c600.

Same problem here. Touchpad stops without any other warning on latitude C600.
When I plug in an usb mouse it works well.

I also have the same problem on a HP ze5170 but a rmmod modprobe doesn't fix it.

Hi

Got the same problem here with my touchpad on edgy (official release). Touchpad frequently stops working. This is my log:

Update... this seems to fix it. Add pci=noacpi noapic to the end of your kernel options not sure if this will apply to everyone but it works for me.

Great, it seems it fixed it for me too! I have a compaq presario v5000 (well, i don't remember the exact model, sorry) with a clean Ubuntu Edgy Eft.

I have a Compaq presario v5120 and it does the same thing, haven't tried it without noacpi yet. I can confirm though that it does this in both Edgy and Feisty but not Dapper.

Most likely this bug is a duplicate of #47971, #34501, and #69322.
