Why do I get a circle when using scroll on trackpad? Especially when using adobe acrobat?
Also sometimes get circle when moving mouse when moving mouse normally?
It’s called Chiral Motion (or perhaps ChiralScroll(TM)) in the trackpad settings. In theory it lets you scroll by moving your finger in a circle on the pad, with scrolling speed determined by how fast you move your finger. In my experience it came up somewhat randomly and was almost uncontrollable, so I turned it off. YMMV, of course.
How do you turn it off? Didn’t see anything under mouse settings. ?
Here’s the steps for the original XP and Synaptics driver that came with my NC10:
Open the Control Panel.
Open the Mouse control panel.
Switch to the Device Settings tab.
Select the Synaptics TouchPad, then click Settings….
Select Virtual Scrolling.
Uncheck Enable ChiralMotion Scrolling.
OK out.
Hope this helps.
Thanks. But now I have scroll bar icon when I try and scroll. And scrolling is very slow. I am accessing pdf which has completely loaded.
You may be interested in the thread Make your touchpad work like a trackball (Synaptics Momentum). Applying momentum has made my trackpad much more usable.
If you poke around the Synaptics panel, you’ll find a whole bunch of settings to play with that may improve your experience.
I was never able to find a set of settings I was comfortable with, so I disabled scrolling completely. (Unfortunate since I really liked trackpad scrolling on my big laptop, but the trackpad on the NC10 is just too small for me.)
In Acrobat/Adobe Reader I use the arrow keys and Page Up/Down to scroll as well as the normal scroll bar and Hand tool.
iv enabled momentum and its awesome,it feels like the kinetic scrolling on the iPhone.
