*** This bug has been marked as a duplicate of 2589 *** I'm sorry, but I fail to see how this bug is a duplicate of 2589, which talks about general configuration of the X server. This bug report is specific to mouse wheel configuration. I'm afraid that my report will get lost, since 2589 has no mention of mouse wheel/button configuration. This seems to not be quite a duplicate of 2589 |

Currently, mouse configuration is not a trivial task. Many new devices come with more than 3 buttons in addition to the mouse wheel. Buttons 4-7 are in practice reserved for the mouse wheel, which means extra buttons should begin counting from 8, but they do not. When mapping the wheel to buttons 4 and 5, extra buttons are by default ignored. Patches are available to "push" the button assignment when the wheel is detected, but this often means extra buttons get assigned as button 6 and up. This means that extra buttons will be treated as a horizontal scroll wheel, which is not the desired behavior. To make a 5 button mouse with wheel work "properly", you have to first configure the mouse with 7 buttons, with the wheel mapped to buttons 6 and 7: Option "Buttons" "7" Option "ZAxisMapping" "6 7" Then, once the X server is running, you have to use xmodmap to remap the buttons: xmodmap -e "pointer = 1 2 3 4 5 8 9" Documentation explaining the proper setup would certainly help, along with an explanation as to why extra buttons begin at 8 instead of 4. This would also server as an official statement from X.org to toolkit and applicaiton developers as to how the mouse wheel is presented in the X11 protocol. Support in the X server for mapping extra buttons starting at 8 would be even better. The ideal solution is a protocol revision or extension that added a wheel event type (and enumerated buttons in logical order), but this requires changes to existing applications and toolkits which won't happen quickly.
