Bug#343728: 097_mouse_zaxis_mapping_pushes_up_buttons should be dropped as of 6.9/7.0 RC3
Christopher Martin
Version: 6.8.99.903.dfsg.1-1
Severity: normal
Tags: experimental
Debian's X.Org packaging includes the patch
097_mouse_zaxis_mapping_pushes_up_buttons.diff, which serves to adjust
mouse button mappings so that users didn't have to use xmodmap to make all
available physical buttons available for use.
In X.Org 6.9/7.0 RC3, upstream made changes to the mouse button handling.
The default ZAxisMapping is "4 5 6 7", accommodating scroll wheels with two
axes. Also by default the mouse physical : logical button mapping is now "1
2 3 8 9 ...", so that all physical buttons can be used (thumb buttons are 8
and 9) without conflict with the scroll wheel.
These changes make Debian's 097 patch obsolete, since now all buttons are
properly exposed by default. Indeed, continuing to include the 097 patch
causes problems, since the buttons are shifted around twice, and it all
becomes very messy. (When wondering why imwheel stopped working with the
latest experimental X, I read up on upstream's changes, and had to rebuild
X without 097 to get the expected new behaviour).
FYI, since you'll probably get questions/bug reports, this change in
behaviour has other implications. Mozilla uses buttons 6 and 7 for
"forward" and "back", but this doesn't work anymore, since those buttons
are now assumed to represent the horizontal axis of the scroll wheel,
whether your mouse has one or not. Users can of course use xmodmap or the
new ButtonMapping xorg.conf option to work around this. As far as I can
tell, Qt applications seem to use 6 and 7 for horizontal scrolling already,
so they shouldn't generate too many reports of brokenness.
Cheers,
Christopher Martin
I'd also like to append this obligatory nag to have bug #237877 looked at :)

Since this patch is still included in the X.Org packaging in unstable,
imwheel is now broken. Please drop the patch (made obsolete by upstream
changes, as explained below) in the next upload.
