Mouse motion in KDE - can I make it linear, turn off acceleration?
 

My cursor is darting around way too fast for my liking! I've failed at all attempts at trying to get it feeling right with KDE. Gnome wasn't a problem--I just turned the mouse sensitivity all the way down and the acceleration down to a comfortable level, but KDE is a different story. I turned the acceleration multiplier down to 1.0x and messed with the pointer threshold, but nothing's doing the trick. I really don't want an acceleration curve at all. I just want nice linear movement at a speed that I can control specifically to my comfort level. what can a n00b do?

Welcome to LQ!

I have had success with setting resolution in /etc/X11/xorg.conf
In that file, find the Section "Inputdevice" that refers to your mouse, and add the following line:
Option "Resolution" "4000"
Save the file (you'll need to be root to do this)
Then restart the X-server with <CTRL><ALT><BACKSPACE> and login again.
You may have to adjust the value of "4000", try 40, 400 etc, till you find a value that works for you.
