Please attach dmesg output and the output of cat /proc/bus/input/devices for
working and non-working kernels.

Those all look sane what does your xorg.conf look like and the Xorg.0.log for
good/bad case.

Good / bad xorg.conf

I'm not making any changes to xorg.conf when switching kernels.

Comment 11 Paul Nasrat 2005-12-23 03:55:58 EST
auto-dev seems to be failing:

(II) Synaptics touchpad driver version 0.14.0
(--) Synaptics auto-dev sets device to /dev/input/event1

(II) Synaptics touchpad driver version 0.14.0
Synaptics no synaptics event device found (checked 1 nodes)

Both /proc/bus/input/devices list event1 as a handler for the synaptics touchpad
does /dev/input/event1 exist under both kernels?
Comment 12 Brian Gaynor 2005-12-23 12:35:08 EST
Paul -

On the working (released kernel) I have a /dev/input/event1 (as well as an
event0, mice, and mouse0). On Dave's test kernel (1771), I only see a
/dev/input/mice, NO event1. 

This machine is running up-to-date FC4, with only Dave's kernel-smp and
kernel-smp-devel installed for testing (no other testing software). 
Comment 13 Brian Gaynor 2005-12-23 12:40:19 EST
On this machine selinux is running in Targeted/Permissive mode.
Comment 14 Dave Jones 2005-12-23 22:57:51 EST
2.6.15 needs a udev update. that'll make this work again.

Comment 16 Niki W. Waibel 2006-01-11 17:00:13 EST
same problem using self-compiled linux-2.6.15:
$ ls -l /dev/input/
total 0
crw-rw----  1 root root 13, 63 2006-01-11 21:47 mice
-> no eventX entries for the synaptics touchpad (on a ibm thinkad t40) anymore ...

$ grep udevinfo linux-2.6.15/Documentation/Changes 
o  udev                   071                     # udevinfo -V

so, what about udev-071 for fc4?
if the kernel interfaces change, the userland-tools have to change as well!

on http://www.kernel.org/pub/linux/utils/kernel/hotplug/ there is version 080
available already...
Comment 17 Paul Nasrat 2006-01-24 16:19:24 EST
udev update required for fc4 by the looks
Comment 18 Harald Hoyer 2006-01-26 08:16:27 EST
does it work with udev-071 in the test update?
Comment 19 Niki W. Waibel 2006-01-30 19:28:55 EST
hmmm ... udev-078-8 from the development repos needs GLIBC_2.4
(glibc-2.3.90-30), and i am not sure if i want to upgrade the glibc already...
Comment 20 Harald Hoyer 2006-01-31 04:32:17 EST
udev-071 for FC-4 can be found here:
Comment 21 kmike 2006-01-31 11:00:51 EST
Entries for Synaptics appear again in /dev/input/ with udev-071 and kernel
2.6.15-1 from FC4-testing.
Comment 22 Niki W. Waibel 2006-02-10 19:16:44 EST
things are fine now with self compiled 2.6.15.x kernels...
Comment 23 Rodd Clarkson 2006-02-12 16:11:06 EST
This is working well with 2.6.15-1.1830_FC4
