[Bug 565543] Re: horizontal scrollbar does not work in VAIO VPCEB15EL touchpad.
simar, thank you for your attention into this problem.
As Segitz stated, VAIO E series area ALPS (multitouch) touchpad.
I think original summary was ok because default 10.04 installation
detect it as AlpS and neither vertical/horizontal scrollbar works.
In a effort to make both work, I blindy updated my kernel to 2.6.34,
which made vertical scrollbar work, later to 2.6.35-rc3 but nothing else
changed.
Then I upgraded Xorg with xorg-edgers's ppa, wich I might say, worsen
the situation as I lost the ability to simulate 3rd button click (mouse
wheel click / middle button click).
I already had installed xserver-xorg-input-synaptics when doing the
xev's test.
$ cat /var/log/Xorg.0.log | grep -i TouchPad
<nothing>
$ cat /var/log/Xorg.0.log | grep -i Synaptics
<nothing>
I had a optical mouse connected last time, so a new grep -i mouse:
$ cat /var/log/Xorg.0.log | grep mouse
$ cat /var/log/Xorg.0.log | grep -i -n1 mouse

That's how my xorg is actually detecting (2) mouse in my system.
It calls my attention the "Vaio Jogdial". I think my laptop does not
physically have one.
