Hello All,

I have a logitech USB optical mouse. Under Gnome, the mouse works fine 80% of the time, however, under heavy CPU and/or hard-drive use, the movement becomes jumpy and erratic, with the cursor often "flung" to the edges of the screen. I have reproduced this behavior under Redhat 9.1 and Mandrake 9.1.

It's more annoying than anything else, but if someone knows a fix, I'd be eternally gratefull

I have a problem which i belive is similar to yours.
I too have a logitech usb optical mouse.
My cursor jumps to the edge of the screen (the bottom most of the times)

I use debian with icewm and this is the only real problem i have
with my os... it is really anoying when you work on graphics that require
finetuned mousemovement.
Ive looked at the configurations in .icewm/preferences etc without finding
anything related to this.
The mousemovement confuses everybody i ask, no one i know knows
the answer.

Altough i searched the forum i did not find this;

i came up on a search on evreka.
read the bottom post. (it states that the driver may be the problem)(ive suspected this
but dont now how to get the right driver yet)
anyway, im a newbie like you, hope you can get some help from the posts.

i dont know if your still around since you made the post a long time ago but im going to post this anyway.

I finally fixed the problem. i edited my configuration in the XF86Config-4 file
located in /etc/X11 as follows:

Section "InputDevice"
Identifier "Mouse1"
Driver "mouse"
Option "CorePointer"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/psaux"


#Option "Emulate3Buttons" "true"
Option "Buttons" "5"
Option "ZAxisMapping" "4 5"

I dont know if this could solve your problem but it could be worth a try. Dont forget to
edit

Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
InputDevice "Generic Keyboard"
# InputDevice "Configured Mouse"
InputDevice "Mouse1"

at the bottom of the file to the name of your device name (in my example "Mouse1")
i made a backup of the original file before editing and testing.

this is a newbies advice. good luck

o i forgot, i used a ps2adaptor for my mouse (as you can see in the configfile)
