ALPS Modification for 2 Finger Scrolling

@Rebellious,
What you are describing is as if the trackpad kext is not installed on your system.
Follow the instructions in this post:
http://www.insanelymac.com/forum/index.php?s=&showtopic=119654&view=findpost&p=1191163
There is also a link to a full voodoops2controller.kext.
I would also check if you have removed all previous voodoops2controller kexts. check your /system/library/extensions and /Extra/Extensions folder.
Hope this helps...

Hi, I'm not sure if I'm posting this in the right place. Supposed to be "no bugs" here but... I didn't see anything in the bugs department. Maybe you can start a thread there and have a link to it here.
I've got a Vostro 1720 with an Alps trackpad. I'll try to gather more info specific to the trackpad model.
Environment: System 10.5.6 (retail) with Chameleon 2 (rc 431), all ps2 nubs and controllers removed (I hope) from both /S/L/E and from Extra/Extensions. Installed voodooPS2 package 0.98. Removed the voodooPS2 control panel from /S/L/PP. Put your control panel in /S/L/PP. Put your modified ALPS for 2 Finger Scrolling into /S/L/E/.
It is close. Keyboard works great. Trackpad pointer, tapping works great.
Scrolling. Two finger scrolling doesn't work. If I try to use the right and bottom edge for scrolling... ah, the right edge does horizontal scroll to the right (but doesn't come back to left) and the bottom controls up and down scrolling in a very jerky manor.
Do I have things in the proper place? Any suggestions?

Khan,
Thanks for the feedback.
Could you run Utilities/Console and search for "abmod" in system.log.
If you get the following line:
ApplePS2ALPSGlidePoint: ABmod, Loading Clicking Settings at Boot: 1, 1, 1
You have installed the driver correctly.
If not, install the full VoodooPS2Controller.kext from the insanelymac link in the previous post.
If you have the driver installed, I think it's a 2 finger scrolling calibration issue.
To confirm this for me, could you use 3 or 4 fingers to scroll?
So to increase the area touched on the touchpad and try moving your fingers up and down simultaneously to scroll.
If this works i shall provide a way to calibrate this driver to suit different trackpads and finger sizes.
I look forward to your feedback.

Thanks AB for the system.log check. It turns out that I chose the voodootrackpad driver when I installed Voodoo 0.98 that was interfering. Might want to mention it.
Yes, once I got drivers sorted out I do have 3-4 finger vertical and horizontal scrolling.
There are some numbers/variables that look like they control track pad characteristics in: /S/L/E/VoodooPS2Controller.kext/Contents/Plugins/VoodooPS2Trackpad.kext/Contents/Info.plist
are these variables that I can play with?
I notice the multi-media buttons don't work to. Minor issue. PEBCAK :)
It would make sense to get the VoodooPS2 control panel working for Alps (and others) so that people can customize their own settings.

I tested this on my HP Pavilion DV2550se. Works great. Can't say thank you enough for this. I did find one problem though. When I bring mine back out of sleep the clicking function stops working until I go back into the system preferences and un-check Clicking and then re-check it.
Anything I can do to get you information about this? I would be more than willing to help with anything.
