Laptop touchpad vert scroll broken upon update

[Zeikcied]

I updated my Uncle's laptop from the previous LTS to 12.04 a few months ago. For some reason, the vertical scrolling with the right edge of the touchpad was broken in the process.

He has an Acer Aspire laptop.

I tried resetting the touchpad settings to default and messing with some of the variables, but nothing has worked. I have no idea what to do.

Try Synaptic touchpad. Its in the repos.

He has xserver-xorg-input-synaptics installed. Heck, I have it installed by default, and I'm on a desktop.

I'm talking about the configuration tool. It has a few options that the normal KDE thing doesn't.

[Zeikcied]

I ran synclient -l and it says that VertEdgeScroll = 1, which is how it's set in the System Settings. So as far as I can tell, it should scroll via the right edge of the touchpad, but it doesn't.

[Zeikcied]

I still could use help with this issue. Someone elsewhere told me that it was a change in the kernel, but I'm not sure of that.

Please show the output of

apt-cache policy xserver-xorg-input-synaptics

I'd like you to try downgrading to the older version of the driver. Run this:

sudo apt-get install xserver-xorg-input-synaptics=1.5.99.902-0ubuntu5

Log out and then log back in for the change to take effect.

If this fixes your problem, then you can place a hold on the package to prevent it from being upgraded:

sudo apt-mark hold xserver-xorg-input-synaptics

[Zeikcied]

That didn't work.

Like I said, it worked fine in the previous LTS release, but it broke after upgrading to Precise back in November. (I procrastinated on upgrading his computer.) So I don't know if I should go further back in versions, or try something else. If it makes any difference, it was a software upgrade, not a fresh install.

How did you perform the upgrade? I.E., did you use the package manager (GUI) or from the console (CLI)?

The GUI.

From the console, what is the result of:

dmesg | grep pad

[Zeikcied]

~$ dmesg | grep pad

Okay. Now, what is the result of:

lsmod | grep mouse
