Mouse Wheel Scroll
 

Is it possible to use the "scroll wheel" on your mouse in linux? its driving me nuts not been able to scroll down the page :rolleyes:

have a M$ IntelliMouse PS2

It works for me here. Do you mean clicking the scroll wheel and moving your mouse up and down? I haven't figured out how to do that either. :(

nope, I just mean moving the wheel to scroll :(

in /etc/X11/XF86Config...Oh, in Mandrake it might be /etc/X11/XF86Config-4

look for "Core pointer's input device Section"
or something similar. add:
You've probably got a line that says Option "Protocol" "Auto"
right now. Change it to:
Option "Protocol" "IMPS/2"
and add:
Option "ZAxisMapping" "4 5"
That should get your scroll wheel working.

You could also add
option "Emulate3Buttons"

to make your wheel act as the third button of your mouse, ie, if there are only two besides it. :D

I did excatly what timedsmith said. But it didn't work for me. In that file there is nothing like "Core pointer's input device Section". But there is options for mouse. It says Option "Protocol" "PS/2". I changed that to Option "Protocol" "IMPS/2" and at the end of it I also added the Option "ZAxisMapping" "4 5" part. But it still dosent work. I'm using mdk9.2 .

This is what my XF86Config-4 looks like. Look for the 2 changes marked with @@@@ sign.

Ditch the emulate three buttons business. This if for two button mice in Gnome - pressing both buttons at once is "emulated" as being a third button. Since your mouse has three buttons, there is no need to emulate a third button. Remove that option from the XFree86 config and see if the scroll wheel works.

k I'll try that.

Waaawoo kc8tbe..... thankssss it works now... also to timedsmith...
my biggest surprice is that unlike windows I dont have to restart the computer to changes to take effect.... It worked immideatly after saving the file...

:) glad you got it working!

very few things in Linux require that you reboot to get them to work.
It's quite nice after having to reboot in WinBloze after every tiny little change.

Amen to that, timdsmith.

A word of warning: updating X, recompiling your kernel, or updating your init system may cause the location of your mouse device to change from /dev/psaux to somewhere else. If you do one of these three things and your mouse stops working, don't panic :eek:! Find the new location of the mouse device and either update all your configs or simlink the new location to the old location.
