touchpad no longer works after update

[Sussch]

After a successful system update and reboot, touchpad was no longer working.
However, an external USB mouse worked just fine.

root@sussch-laptop:/# cat /dev/psaux
was silent during mouse movement.

root@sussch-laptop:/# modprobe -l | grep psmouse
/lib/modules/2.6.24-24-generic/kernel/drivers/input/mouse/psmouse.ko

So, the module was loaded, but the touchpad still wasn't working.

root@sussch-laptop:/# rmmod psmouse
root@sussch-laptop:/# modprobe psmouse proto=imps

And the touchpad works again (without scrolling though) until a reboot / shutdown is made.

root@sussch-laptop:/# lsb_release -rd
Description: Ubuntu 8.04.3 LTS
Release: 8.04

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we can't fix it because your description didn't include enough information. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at https://wiki.ubuntu.com/DebuggingTouchpadDetection

Thanks!

Thanks for the link.
The problem fits in the section "touchpad doesn't work at all".

My touchpad has the following features: horizontal and vertical scrolling, tapping, dragging.
Interestingly though, after reloading the module, scrolling no longer works and tapping can't be switched off.

Hope this helps.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner.
There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test the current Ubuntu development version (10.04). If you can test it, and it is still an issue, we would appreciate if you could upload updated logs by running "apport-collect 419080", and any other logs that are relevant for this particular issue.

10.4 has been working fine so far.
