Comment 21 for bug 565543

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.
