Can't scroll with laptop “pointing stick”

Question

I'm using ubuntu in virtualbox and cannot scroll. What can I do?

EDIT: My host is Windows 7. I'm using a laptop (Lenovo ThinkPad X201s) and I'm trying to scroll not with a mouse wheel but with the red dot which function as a mouse.

Answer 1

Problem solved. Here's how:

• In your host (Windows), go to the SynTP folder. Probably C:\Program Files\Synaptics\SynTP
• Locate the file TP4table.dat and copy it to your desktop (or to somewhere else).

• Open your copy of TP4table.dat and find the line marked in blue in the following screenshot (line 26, right after all the ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;).

• put the following line in there: *,*,VirtualBox.exe,*,*,*,WheelStd,0,9

• Now replace the original TP4table.dat (in C:\Program Files\Synaptics\SynTP) with the modified one (you can backup the original before you replace it).

• restart your computer.

• The thing works.
