I just picked up a cheap cicero mini optical mouse (PS/2) and it gives some choppy movement. My regular ball mouse worked just fine. Any suggestions as to how I may be able to fix this?? I tried adjusting the mouse pointer acceleration and threshold, but no improvement. Maybe I'm doing it wrong?

BTW, this is on Debian.

Are you using 'moused'?

"moused"? What's that?

moused is the mouse daemon. I'm pretty sure you can run X without it but you can have problems. If you're not sure if you're using it, you can check using 'ps' or top.

Oh yeah, you might also want to reconfigure xfree86. I had some problems with an optical mouse once, and I just reconfigured X and it went away. Also, pase us the 'InputDevice" section for your mouse from /etc/X11/XF86Config

Nope, no moused. Here's what I have in my /etc/X11/XF86Config-4 files for my mouse:

Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/psaux"
Option "Protocol" "ImPS/2"
Option "Emulate3Buttons" "true"
Option "ZAxisMapping" "4 5"
EndSection

Section "InputDevice"
Identifier "Generic Mouse"
Driver "mouse"
Option "SendCoreEvents" "true"
Option "Device" "/dev/input/mice"
Option "Protocol" "ImPS/2"
Option "Emulate3Buttons" "true"
Option "ZAxisMapping" "4 5"
EndSection

Hm, I'm not familiar with some of those options. Try setting the Protcol to "auto". Do you know what the "SendCoreEvents" and "ZAxisMapping" do? I've never used them in an XF86Config file, and I use optical mouses all the time, so try commenting out ZAxisMapping.

That's about all I can think of to do, sorry I couldn't be of more help.

Did you compile your kernel with Input Core Support? If not you should try that. Under Input Core Support add mouse support and then set the horizontal and vertical screen resolutions to whatever resolution you will be runnning X in. Hope that helps.
