I have a lenovo thinkpad and the center scrolling button isn't working with the trackpoint anymore… it worked in prior versions of Ubuntu with GPointing Device Settings, but not with 10.10.
Now, it works when I log in, but if i close the lid to my laptop and reopen it, it no longer works. I have to log out then back in. also, i can not uninstall GPointing Device Settings and reinstall because of this error:
There seems to be a programming error
in aptdaemon, the software that allows

related tasks. Please report this

This might mean you need to manually fix this package.
Any ideas? Also, the center click is working like clicking the center of a scroll button it seems. Like, in Chrome, clicking a link opens it in a new tab, etc. How can i fix this?!
===HOW I FIXED IT===
As per the answer i checked as correct i did the following steps in Ubuntu 10.10 and it seemed to work.
First: Go to (in terminal)
Next: create a file named (as root)
Next: Add the following to the file:
Section "InputClass" Identifier "Trackpoint Wheel Emulation" MatchProduct "TPPS/2 IBM TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad / TrackPoint|ThinkPad USB Keyboard with TrackPoint|USB Trackpoint pointing device|Composite TouchPad / TrackPoint" MatchDevicePath "/dev/input/event*" Option "EmulateWheel" "true" Option "EmulateWheelButton" "2" Option "Emulate3Buttons" "false" Option "XAxisMapping" "6 7" Option "YAxisMapping" "4 5" EndSection
Next: Save the file
Lastly: Reboot your computer! (or manually save and reboot Xorg)
