Hi, I've got Gentoo 2005.1 running on my Insprion 9300 (love this setup!). I also have the Microsoft Optical Desktop Elite for Bluetooth 2. However, I cannot get my mouse wheel to scrool in any application. The thumb buttons (4,5) do, however, perform the wheel functions.

For example, in any app with a vertical scrollbar, the thumb buttons (4,5) scroll vertically, and the wheel (6,7) performs forward/back browse in firefox.

Both the mouse and keyboard work fine. My kernel (2.6.13) is patched with the Bluez patch, so I most definitely receive input in /dev/input/mice from all buttons on the mouse. Running 'xev' also shows the events from the buttons are occurring correctly.

I know I have to use xmodmap to switch the functions, but I cannot for the life of me, get it to work. Everything I've read says to use this command and imwheel. I uninstalled imwheel, though, because all of my button events are working in X, but are not mapped correctly.

xmodmap -e "pointer = 1 2 3 6 7 4 5"
But I receive this output:
xmodmap: commandline:0: bad number of buttons, must have 12 instead of 7
xmodmap: 1 error encountered, aborting.

I'm not sure why this occurs, but I tried this and received no error:
xmodmap -e "pointer = 1 2 3 6 7 4 5 8 9 10 11 12"

This, however, doesn't fix the problem. Can't I simply switch their functionality? What am I doing wrong?

Thank you in advance.


Relevant sections of xorg.conf (synaptics device is my touchpad):

It is easier than you think actually.

To switch the button mapping of the scrollwheel and the side buttons:

Change This:
xmodmap -e "pointer = 1 2 3 6 7 4 5"
To this:
xmodmap -e "pointer = 1 2 3 4 5 6 7"

However, I found upon rebooting, it did what I wanted to originally, so do that first, if that doesn't do it, then switch the maps.

Now, assuming you really do need 12 buttons, change the button count to 12, then add 8-12 on the end of the mapping, they shouldn't do anything though, honestly. I am wondering why it wants 12 buttons... that is odd.

A note, I have no "SendCoreEvents" I wonder what that is and does...

No dice. thanks, though

I am guessing it has something to do with your odd 12 button problem. Most likely it is mapping some of the latter and not all of 1-7 like it should...

Ahhh.... I have a thought about that, actually...probably the xmodmap isn't mapping to a single pointing device, as you have a touchpad AND a mouse setup... the touchpad is 5 buttons, and the mouse is 7. As for which comes first and which comes later...or if it even makes that much sense...Logically... you would think either-
"1 2 3 4 5 6 7" Intellimouse
"8 9 10 11 12" Touchpad
or
"1 2 3 4 5" Touchpad
"6 7 8 9 10 11 12" Intellimouse

If it is type 2... instead of swapping the ones I expected 4 5 and 6 7... you would need to swap 9 10 and 11 12...to-
"1 2 3 4 5" Touchpad
"6 7 8 11 12 9 10" Intellimouse

The above assumes it makes logical sense and goes in order. Which it may or may not. I don't know.

If you don't use the touchpad, try disabling or deleting its section entirely. Then instead of haiving to worry about which of the 12:
1 2 3 4 5 6 7 8 9 10 11 12

You will know already which of the 7 you need to mess with:
1 2 3 6 7 4 5

Otherwise, you may have to mess around swapping the map until you figure out which 7 of the 12 affect the Intellimouse, and which 5 affect the touchpad.

xev generates the same button event numbers as the bluetooth mouse. i.e. left click is 1, right click is 3, etc...
