erratic mouse movement

[jnev]

hey guys, this one has been annoying me for a while now. my mouse has really erratic movement in breezy, and it's really starting to get on my nerves. at slow speeds, it moves very slow, with almost zero acceleration, then all of a sudden jumps to a much higher speed when i start to move it a bit faster. also, it jumps a lot across the screen. when i'm doing a cpu-intensive task (like ripping a cd for instance), it becomes 10x worse, as in my comp is barely useable to the extent of the mouse moving so erraticly. in windows, it works 100% normal, the way it should. the mouse is a logitech mx510. here is the xorg.conf for it in case it matters:

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ExplorerPS/2"
Option "ZAxisMapping" "4 5"
Option "Buttons" "10"
EndSection



thanks for any help.

Since I'm assuming your using gnome, you can check Desktop-->Preferences-->Mouse and adjust sensativity and the like, that should help, if its more complex then that, check that its not a hardware issue first (ie same surface, same mouse under win or liveboot)

i already did that (yes i am using gnome). i just tried kde, and my mouse works fine there, no jumping or anything. i dont mind kde, so i might just stay in there instead of using gnome.

except kde has wierd colors, the colors seem to have some distortion and it's a bit blurry in some places. why cant either DE work the way it's supposed to?? lol

can someone please help me with either my mouse problems in gnome or my color problems in kde?

Option "Device" "/dev/input/mice"

Try to change with "Device" "/dev/psaux"

that didn't help. is there a way to change the dpi of the mouse in gnome? in kde there was an option to change the dpi of the mouse from the defualt 400 to 800, which i'm sure is why the mouse performed so much better in kde than in gnome.

Well, having your mouse set to 400 dpi is not an explanation for the problem. Before you set the mouse to 800 dpi in KDE I'm sure it was working fine. At least it didn't change much for me.

I'm using Gnome with a Logitech MX500.

Section "InputDevice"
        Identifier      "Configured Mouse"
        Driver          "mouse"
        Option          "CorePointer"
        Option          "Device"                "/dev/input/mice"
        Option          "Protocol"              "ExplorerPS/2"
        Option          "Buttons"               "7"
        Option          "ZAxisMapping"          "4 5"

Make sure you choose "use X settings" when you login in Gnome.

10 buttons... well that's right I should try that.
