next/prev на мышке

Вот лог иксов, связянных с мышкой:

(II) evdev brain: Rescanning devices (1).
(**) Option "CorePointer"
(**) Configured Mouse-: Core Pointer
(II) Configured Mouse-: Found 2 relative axes.
(II) Configured Mouse-: Configuring as pointer.
(II) Configured Mouse-: Found 3 mouse buttons
(**) Configured Mouse-: Configuring 2 relative axes.
(II) Configured Mouse-: Configured 3 mouse buttons
(WW) <default pointer>: No Device specified, looking for one...
(II) <default pointer>: Setting Device option to "/dev/input/mice"
(--) <default pointer>: Device: "/dev/input/mice"
(==) <default pointer>: Protocol: "Auto"
(**) Option "AlwaysCore"
(**) <default pointer>: always reports core events
(==) <default pointer>: Emulate3Buttons, Emulate3Timeout: 50
(**) <default pointer>: ZAxisMapping: buttons 4 and 5

(--) <default pointer>: PnP-detected protocol: "ExplorerPS/2"
(II) <default pointer>: ps2EnableDataReporting: succeeded
(II) 3rd Button detected: disabling emulate3Button

Всё, отбой. Разобрался.
Во-первых раньше xmodmap видел только 3 кнопки.
Из информации от "cat /proc/bus/input/devices" заменил event0 на event2
xmodmap -pp стал видеть все 9 кнопок.
Далее сделал вперёд назад к событиям 6 7
xmodmap -e "pointer = 1 2 3 4 5 8 9 6 7"

И всё заработало.
