UltraNav Touchpad - Poor Scrolling

I just got my first thinkpad (x201), and can't seem to get used to the touchpad scroll. No matter what I select for scrolling speed in the control panel, I can't disable scrolling acceleration. This leads to either really slow unresponsive scrolling, or hypersensitive scrolling that jumps down the page with poor feedback in between.

With a USB mouse attached to the computer, the scroll wheel obeys the normal 3 lines per click behavior. I was hoping there was some way to force the touchpad to behave this way as well. Anyone have any suggestions on how to disable scrolling acceleration for the touchpad?

 

I would love to get an answer to this one as well.

It's one of the few things that drive me crazy about this laptop! (some little things I don't like, but this is my least favourite part of an overall good machine)

 

Y'all might try Synaptics' own drivers to see if it will make a difference. I replaced the Lenovo driver with Synaptics for other reasons, but it's working fine.

BTW, I am not having problems with the touchpad at all (it is a T510 though). Scrolling is smooth. Palmcheck setting works fine, etc. I also have the sensitivity set on high and it takes barely any pressure at all to move the pointer so the bumps haven't been an issue.

FWIW...........

For those that use Firefox, I found these settings for Firefox 3.6+ that allow you to control Firefox-specific scrolling. In about:config, I set:

mousewheel.withnokey.numlines=3 (windows default)
mousewheel.acceleration.factor=1 (set to constant multiplying factor)
mousewheel.acceleration.start=0 (this setting really doesn't matter since the constant is 1)

I set my scrolling speed in the Touchpad Properties to the slowest. The result is much more consistent scrolling, similar to your regular mouse wheel, no matter how hard or soft I flick the scroll area. Since the majority of my scrolling is web-browser related, I'm happy. Hope this helps anyone who uses Firefox as well. IE, from what i can tell, works pretty good with their smooth scrolling, but I don't use IE.

See this wiki for more info:

For even more fine grained control, check the firefox extension " Yet Another Smooth Scrolling."

Mozilla YASS page for install.

anything for chrome users?

p.s. Thanks!

 

Little late reply, but I came across this thread when looking myself.

There is a Chrome extension SmoothScroll ( https://chrome.google.com/extensions/detail/cccpiddacjljmfbbgeimpelpndgpoknn)

This definitely made scrolling a lot smoother with the trackpoint and center button.

 

I found disabling "Enable Scroll Region Filtering" in the Ultranav utility helped with my erractic scrolling
