Is there another place that I can adjust the acceleration setting for the mouse? The slider bar in the mouse setting manager has no effect.
In the mouse settings, on the Devices tab, on the left side, what items are visible in the list?
If there's a couple, click the one that matches the description of your mouse brand/model, then change your accel/threshold.
If there's only one or two and neither match your mouse, welcome to my world. I've got a Logitech Cordless Desktop Wave, where both the mouse and keyboard use the same receiver and HAL incorrectly reports my mouse as an, "Unknown button", and attempts to configure it as a keyboard. As the evdev driver is used for both mice and keyboards, it's only by sheer luck that the mouse works, although I can't change my acceleration, or threshold, and changing the cursor theme requires me to change the system default.
I've spent a lot of time trying to fix this with custom .fdi files in /etc/hal/fdi/policy/, to no avail.
The only setting available is for a Mac mouse button emulation. I have a Logitec Trackman, trackball.
