Scroll (wheel) speed, mouse acceleration, threshold, sensivity

[Seregwethrin]

Hello;

In Windows, if you move your mouse faster than your mouse's acceleration increases. For example you may move mouse 10cm to move pointer most left of screen to most right by slowly, but if you move fastly, you could take the same distance with moving 3cm. I want to do this in my Ubuntu 9.04, but I couldn't find a setting.

Sensivity: I checked the help file but I didn't understand. Can somebody give an example for what this setting does?

Threshold: I didn't understand same as sensivity.

Also I want to increase my mouse's scrolling speed (wheel speed). Is there any setting or any way to do this?

Thanks.

Still waiting for a solutions...

Go to System > Preferences > Mouse

On the general tab, the slider labeled "Acceleration" next to Pointer speed should do what you want. I tried moving mine up and I can fling my cursor all over the screen with a quick flick.

These sliders are somewhat interdependent, so only move one of them at a time and see what happens. The changes take place instantly with the window still open, so you don't have to click OK or anything.

As far as setting the scroll wheel, I am not aware of any system wide setting for that. It may be possible to change the setting in firefox.
Run Firefox and in the address bar type

about:config

In the Filter field at the top, put in:

mousewheel.withnokey

My default setting shows .numlines as 1 and .sysnumlines as true.

This gives me the default behavior of 3 line scroll with each click of my mouse wheel.

Double click the line that ends in .sysnumlines and the value will change from true to false.

Next, double click the line that ends in .numlines and put in the number of lines you want the page to scroll with each click of the mouse wheel.

The changes take place immediately without having to restart Firefox.

Edit:

I have edited the above for better clarity.

It's what I'm asking for, It's actually the speed of pointer. I want my pointer runs faster when I run mouse faster but not proportional. I want pointer more faster when mouse moves faster.... I want it to adjust itself by the speed of mouse.

I've already done it mate but it just works for firefox, I want scrolling faster at other programs too

This is a known issue. There used to be a fix for this by editing xorg.conf, but all the mouse hardware config is now done by hal and is supposed to be automatic. There will hopefully be a change in the upcoming gnome that will allow us to adjust more of the mouse features including the scroll wheel, but for now, I don't think it can be done.

Thanks for explanation mate, I hope new gnome will support as you said.

Is there still no fix for the scroll speed? It is making my ubuntu experience really bad, almost unbearable, having my wheel scrolling half a page even with a gentle touch

Here are settings within firefox itself that affect scroll wheel speed. Only for Firefox though, not the rest of Gnome.

How to change the number of lines that scroll in Firefox with each click of the mousewheel.

Run Firefox and in the address bar type
Code:

about:config

In the Filter field at the top, put in:
Code:

mousewheel.withnokey

My default setting shows .numlines as 1 and .sysnumlines as true.

This gives me the default behavior of 3 line scroll with each click of my mouse wheel.
