Weird mouse behaviour in Debian Wheezy (jumpy cursor)

Question

When I move my mouse slowly over the desktop the pointer jumps often a few pixels (one or two) in the opposite direction of which I move my mouse. Horribly when trying to set the cursor around some semicolons in eclipse. I guess this is the result of a wrong set resolution. I suppose this is because the mouse was set initially really fast and even if I do xset m 1/2 3, the mouse is just to fast and unprecise for me.

It aready tried to configure the xorg.conf like this:

Section "InputDevice"
    Identifier  "Configured Mouse"
    Driver      "mouse"
    Option      "Device"    "/dev/mouse"
    Option      "Protocol"  "Auto"
    Option      "Name" "Logitech G3"
    Option      "Resolution" "2000"
EndSection

But with no effect.

EDIT But one new thing I recognized is that, in the mouse settings, I can slide the slider to max or to min. Mouse behaviour (sensitivity) does not change. I found somthing curoious too in /var/log/Xorg.0.log:

Still my question is:

How do I setup my mouse correctly in Debian wheezy?

Answer 1

Okay well that took a while. But I got a solution. Meanhile I even bought a new mouse.

When you have a mouse with a high dpi you can use its standard dpi with minimum acceleration (which is anyway going to be to fast) follow these steps:

1. Get xinput

   $ sudo apt-get install xinput

2. List your input devices

   xinput --list

   You should get an output like this:

   ⎡ Virtual core pointer                      id=2    [master pointer  (3)]
   ⎜   ↳ Virtual core XTEST pointer            id=4    [slave  pointer  (2)]
   ⎜   ↳ HID 1d57:0005                         id=8    [slave  pointer  (2)]
   ⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
       ↳ Virtual core XTEST keyboard           id=5    [slave  keyboard (3)]
       ↳ Power Button                          id=6    [slave  keyboard (3)]
       ↳ Power Button                          id=7    [slave  keyboard (3)]
       ↳ AT Translated Set 2 keyboard          id=10   [slave  keyboard (3)]
   

3. I my case my "HAMA uRAGE" is HID 1d57:0005. Remember its id.

4. Now comes the magic. I would prefer to be able to increase the resolution but debian obv dont want me to. Type in:

   xinput set-float-prop <id> 'Device Accel Constant Deceleration' <d>;
   

where is to be replaced by your mouse's id and the deceleration factor. Your have to play around a little bit. Like me. At least X doeas not need a restart for applynig the changes. Greets

EDIT:

To make it permanent edit X11 settings.

sudo nano /etc/X11/xorg.conf

Add: Option "ConstantDeceleration" "10"

Example:

Section "InputClass"
   Identifier "My mouse"
   MatchIsPointer "true"
   Option "ConstantDeceleration" "10"
EndSection
