Touchpad stops responding

[Emil Oppeln-Bronikowski]

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:

I am using a HP Pavillion 8000 Series Notebook. The exacty Type is this one dv8391dv.

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.

[David Caro (dcaro)]

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.

[Mike Dahlgren (dahlgren)]

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.
