Variable Mouse Acceleration - Movement

[mr.pipo]

Hello, first sorry for my bad english.
It is possible to turn off this new OSX feature - variable mouse acceleration in OSX? If I make a slow movement with my mouse, the mouse cursor moves slowly. But if I do the same distance quickly, the mouse cursor moves very fast. OS 9 doasn't have this feature that' s why I like this old system much more.

1) Don't worry about good or bad English. You have better English than many of the members of this board.

2) Try USB Overdrive.

Take a look at MouseZoom

... these applications don't solve this problem. I've tried them. They can only increase the accleleration more then apple original panel (more than 1.7)
:-( and they have additional features as well.

You do not need to be logged in as root to perform this mod.
For modifiction of the variable I will use the app "TextEdit". Open TextEdit from your Applications folder. Press "Command+O" to open a document.
In the "Go to" location type this:
/Users/your_username/Library/Preferences/.GlobalPreferences.plist

The location is case-sensitive and don't forget the little period before GlobalPreferences.plist. It is invisible and will not be found without that initial period.

Now you should have this file in front of you:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist SYSTEM "file://localhost/System/Library/DTDs/PropertyList.dtd">
<plist version="0.9">

Blah,Blah,Blah-- Lots of variables in here, Blah, Blah, Blah--
Look for this line near the bottom of the document:

<key>com.apple.mouse.scaling</key>
<real>1.700000000000000e+00</real>

Just alter the number to what you would like your new speed to be and save the document and you are done with the configuration.
Be sure to not get out of control with your number, my adjusted mouse setting is

<key>com.apple.mouse.scaling</key>
<real>3.000000000000000e+00</real>

...and that ‘s it.

Log out and then back in.
You can change it to what you want and try it, 1.0 mybe or lower.

=====================

You can also do this;

Type this in terminal:

defaults write -globalDomain com.apple.mouse.scaling -float 3.0

3.0 being the speed of your choice

Hallo boys,
you haven't understood me. Your advices are completly wrong.
Here is the description of this problem
once again from another user from another forum:
(He is better in english then me)
He exactly explains the problem in OSX

I notice an inconsistency in its movement. The cursor seems to only move fast when you jerk your mouse around quickly, but when you move the mouse slowly, the tracking speed drops much lower than it should. In other words, you can move the mouse the same physical distance, but how far the cursor travels across the screen seems to depend on how fast you move your mouse, not how much. Is there any way to fix this?

 

[Arden]

This is mouse acceleration. It is there to allow you to move the cursor to another part of the screen quickly, to try to reduce repetitive strain injury (RSI). I don't know if acceleration is enablable in USB Overdrive in OS X (which doesn't work for me ), but it is in 9.

What kind of problem is this presenting for you?

 

[mr.pipo]

I had to make a clean install of OSX 10.2.6, because USBOverdrive X couldn't recognise the mouse. It works now. Thanx. This appl. is cool, but 80dpi is too slow ...

 

[Arden]

Cool. If 80 DPI is too slow, try 100 or 110.

 

[mr.pipo]

... but 80 dpi is fast in and 1400 is slow in USBOverdriveX.
I red on the web they are working on better speed. (40 dpi ? maybe).

 

[Arden]

Hmm, either I forgot or I didn't know that. Try 60 or thereabouts, in that case.

 

[mr.pipo]

80 dpi is the maximum at this time in Overdrive

 

[Arden]

Well, I'm sorry, then. Use Bob's method to speed up your mouse a bit, maybe .5 points.

 

[monktus]

Related mouse problem (maybe). Every so often my cursor will fly to a random corner of the screen which can be quite annoying, especially when selecting something. Anyone else had this problem? I'm using a Logitech 2 button wheel mouse (optical) but I'm pretty sure that it happened a couple of times when I used my puck mouse (eeuch). Machine specs in sig. Any ideas? Danke.

 

[mr.pipo]

What about your mouse pad. If you use an optical mouse be careful to use a mouse pad with one color areas. Try to change it or use your mouse on a table only.

 

[Arden]

Yes, if you have a mousepad with light and dark areas, moving over one from the other will confuse the sensor in your mouse and cause the cursor to skip.

 

[monktus]

Ah, hadn't thought of that. Interesting, as my mouse pad is a picture of Buffy, that could well be the problem. Cheers.
