Ubuntu 10.10: Lenovo Trackpad Scrolling not working

[Narretz]

Hello,

as you can read from the topic title, I cannot scroll in Ubuntu 10.10 on a Win 7 Host with a Lenovo L412 (VBox 4.0.4 OSE). When I press the middle "mouse" button, the mouse cursor changes to a scrolling symbol, but i cannot scroll moving the trackpad.
So far I have:

- updated and upgraded Ubuntu 10.10
- added the Virtual Box Guest additions
- updated my Lenovo UltraNav Drivers to the latest version

- made sure the Synaptics TouchPad driver for X is installed, but as far as I understand that doesn't do anything because VBox recognizes the trackpad as a generic mouse.
- I tried this workaround here: http://kailapis.wordpress.com/2009/08/2 ... irtualbox/ (adding some lines to some synaptics .dat files in Windows, to chnage the behaviour of the vbox)

In Ubuntu's mouse preferences, I can only change settings for left and right click, no middle mouse button seems to be available.

I think that's what I tried so far, I will add more if I can think of it.

Ok, the fix was actually kind of in the link I posted, but this one is better:

However, before that I updated my UltraNav Drivers.

Unlike the original poster, I am unable to get this going.

I did a search on C:\ and it found tp4table.dat in C:\Program Files\APoint2 but when I look at the access dates, it looks like the files haven't been accessed in years. Nevertheless, I tried changing the file as described in the above web pages, but it doesn't help.

Although I'm running somewhat old software (virtualbox 3.2.6 with Ubuntu 9.10), I think the problem is on the Windows side. Do I need to create a new tp4table.dat somewhere to get this to work?
