11.04mousewheel
I have done a clean Natty install having bought a new SSD and find that in applications (ahem) such as Minecraft, and in the default web browser Firefox, the mouse scrolls too far .
So for example in Minecraft the mouse wheel jumps multiple items rather than one with each mouse wheel roll. With Firefox the page leaps quite a distance with each mouse wheel roll.
Any ideas where I might adjust this?
Above solutions didn't work for me however...
The fix for me for this (I had the problme for months!) was kinda surreal and like most folks I didn't believe it until I did it:
Turns out some MS mice have a scrollwheel bug.
Try unplugging the USB cable / dongle then plug back in.
That's it!
Now my mouse moves normally (one line at a time, not half a screen!)
This worked even though I use a 4-port screen/keyboard/mouse KVM box ! Yeah!
You can use some firefox options to both disable the default action which is to paste on clicking the middle-mouse button and also to turn on auto-scrolling.
First - in the Firefox - Preferences - Advance settings ensure you have the following options checked:
Then in the Awesome bar type about:config
Search for *autoscroll and double click *general.AutoScroll to change from "false" to "true"
Now search for middlemouse
Then restart firefox
When you middle click you should now see this symbol to scroll:

As a workaround, try unplugging your mouse and plugging it back in. I run into this issue when the mouse is plugged into my laptop when Ubuntu boots up. Using this workaround fixes the issue for me.
