Bug#437923: xserver-xorg-input-synaptics: Similar symptoms after a kernel upgrade
Package: xserver-xorg-input-synaptics
Version: 0.14.7~git20070517-2
Followup-For: Bug #437923
My touchpad stopped working after a kernel upgrade, too. My kernels are
built from linux-source-2.6.* with make-kpkg.
With the latest 2.6.18 kernel, touchpad works OK.
With 2.6.21 and 2.6.22 (from unstable), the touchpad doesn't work. I can be
more specific, though: it actually isn't detected by the synaptics driver.
When it works, here is the relevant part of Xorg.0.log:

####################################################
As I put my touchpad as a core device, X refused to start, hence I realized
it quickly. Nonetheless, with these kernels, "cat /dev/input/mouse0" shows
that the touchpad events are recognized, i.e. moving the finger on the
touchpad makes something appear on the console. The evdev driver of XOrg is
loaded, and the evdev kernel module in compiled in the kernel (putting it as
an independent module yielded the same result, anyway).
Hence I think the problem lies somewhere in the detection of the touchpad
and the kernel. Googling the problem directed me also to this page:
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/89517
While not totally similar, the symptoms seem related.
