sk-8845 – ubuntu linux...middle button scroll and disabling...

时间：2010-08-10 来源：plupy

IBM Ultranav USB Keyboard是我的最爱，但在UBUNTU10.04上的支持还是不够，虽然能使用指点杆，但最喜爱的中键滚轮不能配，还有不喜欢的触摸板也不能关掉。我用的型号是SK-8845。因此从网上搜下，真发现了一些有用的方法，下面是我用之有效的方法：

一、中键滚轮：

Step 1. Create a new file
sudo nano /usr/lib/X11/xorg.conf.d/20-thinkpad.conf

Step 2. Insert the following
Section "InputClass"
Identifier "Trackpoint Wheel Emulation"
MatchProduct "TPPS/2 IBM TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad / TrackPoint"
MatchDevicePath "/dev/input/event*"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "2"
Option "Emulate3Buttons" "false"
Option "XAxisMapping" "6 7"
Option "YAxisMapping" "4 5"
EndSection

Step 3. Save file, restart computer, and enjoy!

二、关闭触摸板

网上找的一些资料都是给笔计本上的触摸板用的，给这个键盘用的只有一个帖子，但系统太旧，我用了没有效果。

自己搞了一下，竟然能行，下面是步骤：

1. 使用cat /proc/bus/input/devices查看Touchpad映射的是哪个设备： $ sudo cat /proc/bus/input/devices I: Bus=0003 Vendor=04b3 Product=3019 Version=0100
N: Name="Lite-On Tech IBM USB Travel Keyboard with UltraNav"
P: Phys=usb-0000:00:1d.0-1.3/input0
S: Sysfs=/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.3/2-1.3:1.0/input/input4
U: Uniq=
H: Handlers=kbd event4
B: EV=120013
B: KEY=10000 7 ff9f207a c14057ff febeffdf ffefffff ffffffff fffffffe
B: MSC=10
B: LED=7

I: Bus=0003 Vendor=04b3 Product=3019 Version=0100
N: Name="Lite-On Tech IBM USB Travel Keyboard with UltraNav"
P: Phys=usb-0000:00:1d.0-1.3/input1
S: Sysfs=/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.3/2-1.3:1.1/input/input5
U: Uniq=
H: Handlers=kbd event5
B: EV=13
B: KEY=7fff8000 0 0 0 0 0 0 1f 0 0 28 c000d000 1e0000 0 0 0
B: MSC=10

I: Bus=0003 Vendor=06cb Product=0009 Version=0100
N: Name="Synaptics Inc. Composite TouchPad / TrackPoint"
P: Phys=usb-0000:00:1d.0-1.4/input0
S: Sysfs=/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:1.0/input/input6
U: Uniq=
H: Handlers=mouse1 event6
B: EV=17
B: KEY=70000 0 0 0 0 0 0 0 0
B: REL=3
B: MSC=10

I: Bus=0003 Vendor=06cb Product=0009 Version=0100
N: Name="Synaptics Inc. Composite TouchPad / TrackPoint"
P: Phys=usb-0000:00:1d.0-1.4/input1
S: Sysfs=/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:1.1/input/input7
U: Uniq=
H: Handlers=mouse2 event7
B: EV=17
B: KEY=70000 0 0 0 0 0 0 0 0
B: REL=3
B: MSC=10 2. 然后用cat /dev/input/mouse1来测试mouse1是不是触摸板，不行就试mouse2： $ sudo cat /dev/input/mouse1 经测试，mouse1即触摸板，重点看这句：H: Handlers=mouse1 event6 3. 查看/var/log/Xorg.0.log，找到与触摸板相关的行，可以看到/dev/input/event6即为触摸板了，它是由evdev来驱动的： (II) config/udev: Adding input device Synaptics Inc. Composite TouchPad / TrackPoint (/dev/input/event6 )
(**) Synaptics Inc. Composite TouchPad / TrackPoint: Applying InputClass "evdev pointer catchall "
(**) Synaptics Inc. Composite TouchPad / TrackPoint: Applying InputClass "Trackpoint Wheel Emulation"
(**) Synaptics Inc. Composite TouchPad / TrackPoint: always reports core events
(**) Synaptics Inc. Composite TouchPad / TrackPoint: Device: "/dev/input/event6"
(II) Synaptics Inc. Composite TouchPad / TrackPoint: Found 3 mouse buttons
(II) Synaptics Inc. Composite TouchPad / TrackPoint: Found relative axes
(II) Synaptics Inc. Composite TouchPad / TrackPoint: Found x and y relative axes
(II) Synaptics Inc. Composite TouchPad / TrackPoint: Configuring as mouse
(**) Option "Emulate3Buttons" "false"
(II) Synaptics Inc. Composite TouchPad / TrackPoint: Forcing middle mouse button emulation off.
(**) Option "EmulateWheel" "true"
(**) Option "EmulateWheelButton" "2"
(**) Option "YAxisMapping" "4 5"
(**) Synaptics Inc. Composite TouchPad / TrackPoint: YAxisMapping: buttons 4 and 5
(**) Option "XAxisMapping" "6 7"
(**) Synaptics Inc. Composite TouchPad / TrackPoint: XAxisMapping: buttons 6 and 7
(**) Synaptics Inc. Composite TouchPad / TrackPoint: EmulateWheelButton: 2, EmulateWheelInertia: 10, EmulateWheelTimeout: 200
(II) XINPUT: Adding extended input device "Synaptics Inc. Composite TouchPad / TrackPoint" (type: MOUSE)
(II) Synaptics Inc. Composite TouchPad / TrackPoint: initialized for relative axes.
(II) config/udev: Adding input device Synaptics Inc. Composite TouchPad / TrackPoint (/dev/input/mouse1)
(II) No input driver/identifier specified (ignoring) 4. 修改/usr/lib/X11/xorg.conf.d/05-evdev.conf中内容，将event6排除出去： Section "InputClass"
    Identifier "evdev pointer catchall"
    MatchIsPointer "on"
    MatchDevicePath "/dev/input/event[!6] "
    Driver "evdev"
EndSection 5. 或者，我们将需要的input pointer加上即可，如我们需要trackpoint和鼠标，它们分别对应/dev/input/evnet7和/dev/input /evnet8，因此修改如下： Section "InputClass"
    Identifier "evdev pointer catchall"
    MatchIsPointer "on"
    MatchDevicePath "/dev/input/event[7,8] "
    Driver "evdev"
EndSection 6. 最后重新启动X： $ sudo service gdm restart
