我是一名左撇子 ThinkPad 用户，习惯于使用默认右手配置的 TrackPoint。但是，当我使用蓝牙鼠标时，我希望按钮采用左手布局。在 11.04 (Natty) 中，我可以使用以下方法手动配置新输入，但我希望在鼠标连接时自动应用它。我按照 xorg 文档创建/etc/X11/xorg.conf/99-ms500mouse.conf并将以下内容放入其中：
Section "InputClass"
Identifier "Microsoft Bluetooth Mouse 5000 button remap"
MatchProduct "Microsoft Bluetooth Notebook Mouse 5000"
MatchDevicePath "/dev/input/event*"
Option "ButtonMapping" "3 2 1 4 5 0 0 0 0 0 0 0"
EndSection
这最初似乎有效（GDM 似乎正确使用了它），但是当我登录并启动我的 X 会话时，按钮神秘地恢复了：
$ xinput get-button-map "微软蓝牙笔记本鼠标 5000"
1 2 3 4 5 6 7 8 9 10 11 12
以下是我的/var/log/Xorg.0.log：

如您所见，它似乎应用了我想要的按钮映射（即交换按钮 3 和 1 并禁用所有其他按钮），但会话启动后，这个映射就消失了。我如何确保这些设置保持不变？
多谢！

找到问题了。gnome-settings-daemon 正在用系统范围的设置（设置为右手）覆盖我为鼠标提供的设置。避免此行为的唯一方法是启动gconf-编辑器并找到钥匙：
/apps/gnome_settings_daemon/plugins/mouse/active
并取消设置。这将阻止它覆盖 xorg.conf（或 etc/X11/xorg.conf.d/ 中的片段文件）中指定的设置。
