Best to just leave off the "buttons" option. >Question 2: what is the difference in the use of ZAxisMapping, >XAxisMapping, YAxisMapping?? ZAxisMapping is for the vertical scroll operations and as far as I know always needs exactly two button numbers as arguments (one for scroll up, the other for down). I'd assume X and Y are similar for different scroll directions (though I'm not sure why Z is for vertical scrolling, you'd think that would be Y :-). I use a usb trackball with 4 buttons and a scroll ring in addition to the ball (a kensington expert mouse) and getting it setup was a little tricky. Here's the input device section I wound up with: Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "Auto" Option "Device" "/dev/input/mice" Option "ZAxisMapping" "4 5" Option "Emulate3Buttons" "no" Option "DragLockButtons" "2 1" EndSection The "auto" protocol was important. There are uncounted zillions of things you can apparently say there, all utterly undocumented, but "Auto" means "Hey, X, figure it out for yourself!" which is the only setting I ever got to work for any mouse :-). I have no idea where /dev/input/mice comes from either, but it has always worked, so that's what I use. The drag lock is important to me with a trackball, but probably not so important for a regular mouse. The definition above says that button 2 when clicked once will act as though button 1 is held down until I click again (it is very difficult to hold down a button and roll the mouse at the same time :-). That may seem like I have "used up" the real button two, but I also have the following Xmodmap entry defined: ! Setup buttons for trackball pointer = 1 8 3 4 5 6 7 2 9 That swaps buttons 2 and 8. The confusing part is that you have to use the pre-xmodmap button numbers in xorg.conf. I turn off the emulate 3 buttons since I really have 4 buttons, I don't need the emulation. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
