 Posted: Tue Feb 22, 2005 11:16 am Post subject: USB mouse problems [solved] |
 |
|
Hello,
I'm having a few problems getting my usb mouse to work correctly.
Problems:
- The cursor moves to fast. The shortest possible distance I can move the cursor is something like 3 pixels. This is with all acceleration turned off: xset m 1 1.
- The cursor is extremely laggy on heavy cpu loads.
- The scroll wheel doesn't work. (middle mouse button does work)
I don't know if these problems are related.
System info:
xorg 6.8.0-r4
kde 3.3.92
kernel gentoo-dev-sources 2.6.10-gentoo-r7
xorg.conf mouse section:
| Code: |
Section "InputDevice"
Identifier "Dell Mouse"
Driver "mouse"
Option "Device" "/dev/usbmouse"
Option "Protocol" "IMPS/2"
Option "ZAxisMapping" "4 5"
EndSection
|
I tried setting the mouse resolution to different values in the xorg.conf but I noticed no difference in the mouse behaviour.
[edit]
If I do 'cat /dev/usbmouse' I get no response from the scrollwheel. All other actions (moving, other buttons) produce data.
[/edit]
[edit2]
I solved all the problems. Most mouse problems where caused by not enabling UHCI in the kernel.
The laggy mouse was caused by not enabling DMA on my disk.

what if you change your device to /dev/input/mice? That's what I have and my usb mouse runs perfectly.

/dev/usbmouse is a symlink to /dev/input/mice
But thanks for replying  |

Specify the number of buttons your mouse has.
Also, do you know who the maker of the mouse is? I know it says Dell, but someone else usually makes the mouse, Logitech etc...
If its a logitech, I can help you out more if the following doesnt work: | Code: |
Section "InputDevice"
Identifier "Dell Mouse"
Driver "mouse"
Option "Device" "/dev/usbmouse"
Option "Buttons" "5"
Option "Protocol" "IMPS/2"
Option "ZAxisMapping" "4 5"
EndSection
|
Replace the number of buttons with however many you have, including the mousewheel up and down as buttons.
On my mouse, which has left, right, 2 more left and right buttons, mousewheel down and up, and the mousewheel itself, I have 7 buttons.
You can also try changing the protocol from IMPS/2 to ExplorerPS/2 |

Thanks for you help, but sadly it didn't work.
My mouse has 5 buttons (left, right, middle, scroll up, scroll down). So I put the 5 button option in my mouse input section, but it didn't help.
Changing the protocol from IMPS/2 to ExplorerPS/2 also didn't make a difference.
I don't think the scrollwheel problem has something to do with xorg.conf because the device itself doesn't generate data when I use the scrollwheel. |

The problem is even worse then I first thought. When the cpu is busy, like >80%, the mouse not only gets laggy, it also sends click events. When I move it across the screen in KDE in drags windows and presses buttons. And it's not only the mouse, the keyboard has the same problems.
I'm pretty sure that I have configured something wrong in the kernel. Any insight into this problem is appreciated.
[edit]
Ok, it's not the CPU load. It's the disk. Whenever the disk is busy reading or writing something the mouse behaviour becomes erradic.

From looking around mailing lists and whatnot, it seems that Dell mice have issues in general.
To be honest, the easiest way to fix this is to go and buy a new mouse. Even a bog standard mouse would probably be better. |

Thanks for the replies.
I figured out the laggy mouse problem. I didn't turned on DMA on my disk.....  |
