KDE scroll speed is not proportional to wheel speed

This is a bug that has been known for nearly ten years, and the community, for whatever reason, has intentionally ignored it. The developers who have made an attempt to fix this appear to get frustrated and quit. This appears to be most common in wireless or optical mice produced by Microsoft. That might have something to do with their choice to ignore a bug that end-users have been reporting for a decade. There is no setting for scroll speed in either Gnome or KDE. I think this is more of an issue with the X window system than either window manager. There's a way to fix this permanently, in Firefox, only. http://ubuntuforums.org/showthread.php?p=7416951

Otherwise, try unplugging the mouse's wireless dongle from your USB port, leave it for a few seconds, then plug it back in. Seems to work.

Having the same issue here. I'm learning that a scroll wheel is a luxury... It makes me miss the old Macintosh.

It seems that only the mouse pointer has the acceleration settings.

There are wish reports:

The Xorg report seems to have a patch. So maybe the acceleration is soon available ? The latest comment is 2011-10-09.
