Public bug reported:
Sometimes when I boot my laptop up scrolling area on a TouchPad doesn't work
and Touchpad configuration pages are not present in Preferences->Mouse menu. In
such cases I just reboot my laptop, and then everything works fine.
But in most times it boot's up having all TouchPad functionality Ok.
System version: Hardy 8.04.1
Laptop: Toshiba Tecra M7 (it's a Tablet PC)
Kernel: 2.6.24-22-generic #1 SMP Mon Nov 24 18:32:42 UTC 2008 i686 GNU/Linux
I've figured out that it happens (no scrolling) because of Synaptics
TouchPad not being detected in such cases.
Here goes what I can find (related to mouse) at /proc/bus/input/device in cases
of scrolling failure:

ThinkFinger is a fingerprint scanning device built into my Tablet.
What is a GlidePoint I don't know, but I suppose that it may be a sort of a
mini joystick built into the lid that is used to operate this laptop in Tablet
mode.
sudo lshw shows this:

-----------------------
I've tried to rmmod and modprobe psmouse just to be sure that it does
not solve the problem. So, it really does not :) , 'cause the device is
not even detected properly.
Thanks everyone in advance and anyway. :)
P.S. Haven't tested that on Intrepid, 'cause I use LTS version and the
bug is not persistently showing up. So I can not just boot once into
Intrepid and check if the bug is still there.
