Comment 1 Valdis Kletnieks 2005-12-30 03:00:17 UTC 
Testing with 'xev' shows that what should be buttons 1-7 are in fact seen as 1,
2, 3, 6, 7, 8, 9.  I found the problem when xmodman complained:

xmodmap -e "pointer = 1 7 2 6 3 4 5"
xmodmap:  commandline:1:  bad number of buttons, must have 11 instead of 7
xmodmap:  1 error encountered, aborting.

Wow. It's not a bug, it's a feee-ture.

https://bugs.freedesktop.org/show_bug.cgi?id=4915

What I *used* to have was xmodmap -e "pointer = 1 7 2 6 3 4 5" (which basically
moved mouse buttons 2 and 3 to physical buttons I preferred).

Now I have to use xmodmap -e "pointer = 1 7 2 6 9 4 5 8 3 10 11" (injecting
gratuitous non-existent 8-11 - 8 and 9 as padding are irritating).

I'm not sure *how* to document this user-visible change - in particular, note
that xmodmap is usable by users, who will have to work around any ZAxisMapping
that the sysadmin set up.....

Please upgrade to xorg-x11-drv-mouse-1.0.3.1-1 and update the report to indicate
if the problem still exists in the current build.  Some bugs were fixed at the
last minute which may resolve this.

TIA
Comment 5 Mike A. Harris 2006-02-09 12:09:07 UTC 
Assuming this is resolved in the latest packages as there has been no
feedback for over a week.

If the problem still exists in the latest packages, after reconfiguring
the X server from scratch with system-config-display and system-config-mouse,
please reopen with updated details.

Setting status to "RAWHIDE".
