罗技木星轨迹球具有四个按键，且是对称的，因而不论左右手都适合使用。Picture缺点是不具滚轮功能，但可以设定来启用此功能。

安装[编辑 | 编辑源代码]

无缺额外驱动程式。在系统启动或在已开启系统中连接时，即可侦测到罗技木星。罗技木星虽然可以当作一般鼠标来使用，不进行设定，然而你可能想要启用滚轮功能或客制化按键。

基本功能[编辑 | 编辑源代码]

无论何种硬件设定，木星的硬件ID固定的。

当没有额外设定时，按钮会为下列功能：

ID	硬件动作	结果
1	左大按键	左键
2	双击（大按键）	中键 †
3	右大按键	右键
4	“无”	-
5	“无”	-
6	“无”	-
7	“无”	-
8	左小按键	上一页
9	右小按键	下一页

ID	硬件动作	结果
4	球体向下	鼠标向下
5	球体向上	鼠标向上
6	球体向左	鼠标向左
7	球体向右	鼠标向右

Template:Note (繁体中文)

Template:Note (繁体中文) 在“滚轮模式”使用轨迹球时，也可使用一些鼠标手势的功能，例如，在同时按压Ctrl键跟滚动滚轮可以缩放浏览器中的字体。使用轨迹球时，则需同时按压Ctrl与“滚轮模式按压键”来触发功能。

Two expositions help you configure a trackball with buttons for click, middle-click, right-click, and scrolling. The first exposition uses Xorg Input Hotplugging; the second does not. Edit them to suit your preferences.

Add this entry to your /etc/X11/xorg.conf:

Section "InputClass"
    Identifier   "Logitech Trackball"
    MatchProduct "Trackball"
    Option       "ButtonMapping"      "1 8 3 4 5 6 7 2 9"
    Option       "EmulateWheel"       "True"
    Option       "EmulateWheelButton" "9"
    Option       "XAxisMapping"       "6 7"
EndSection

To learn more about the used parameters you should read the apropriate section in the evdev man page.

Without Xorg hotplugging[编辑 | 编辑源代码]

Template:Note (繁体中文)

The mouse device entry in /etc/X11/xorg.conf should look like this:

Section "InputDevice"
    Identifier "Mouse0"
    Driver     "mouse"
    Option     "CorePointer"
    Option     "Device"             "/dev/input/mice"
    Option     "Protocol"           "ExplorerPS/2"
    Option     "Buttons"            "9"
    Option     "ZAxisMapping"       "4 5"
    Option     "XAxisMapping"       "6 7"
    Option     "EmulateWheelButton" "9"
    Option     "EmulateWheel"       "true"
EndSection

The "Auto" option for "Protocol" works fine, too. Of course you can use the name you prefer as the Identifier, as long as it is the same you use as InputDevice in the Section "ServerLayout" .

Sample configuration[编辑 | 编辑源代码]

The sample configuration modifies and extends the basic function of the Marble Mouse.

In this example, either of the two small buttons may be clicked to send a wheel-click. Wheel-click means the same as "middle-click" here. In addition, one of the small buttons provides scrolling in conjunction with the trackball. Note that only one small button has the ability for scrolling, although both small buttons are able to wheel-click.

Finally, clicking both large buttons simultaneously sends the browser back event. There is no button to send browser forward.

ID	Hardware Action	Result (this configuration)	New assignment
1	Large button left	normal click	1
2	Both large buttons	browser back	8
3	Large button right	right-click	3
8	Small button left †	wheel-click	2
9	Small button right ‡	wheel-click	2

Configuration file[编辑 | 编辑源代码]

The following lines are appended to /etc/X11/xorg.conf.d/10-evdev.conf

Note: Users of other Linux distributions may find the configuration file in another location. Ubuntu uses /usr/share/X11/xorg.conf.d/10-evdev.conf

This example is set up for right-hand placement with horizontal scrolling disabled.

#       The Logitech Marble Mouse buttons are mapped [A-D] from left to right:

Restarting X[编辑 | 编辑源代码]

Changes made to xorg configuration files do not take effect until the X session is restarted. To restart the X session, simply log out from your window manager and log back in.

Or, depending on what display manager you use, you can use one of the following commands:

Default Ubuntu (with LightDM) : sudo restart lightdm

Gnome (with GDM) : sudo restart gdm

KDE (with KDM) : sudo restart kdm

Minimal configuration[编辑 | 编辑源代码]

Using evdev[编辑 | 编辑源代码]

At times it can be useful to start with the absolute minimum and build from there. This is one facet of The Arch Way. In this spirit, I decided to see how few lines I might use to create a usable Marble Mouse configuration.

You can omit all configuration lines and the Marble Mouse is still usable for basic pointing and clicking. However, it will not be able to scroll. The "both-large-button" simultaneous click produces indeterminate results — experimentation shows this.

Given that you are satisfied with default button settings and you wish only to enable scrolling and the "both-large-button" click, you need these lines. The following lines are appended to /etc/X11/xorg.conf.d/10-evdev.conf.

Section "InputClass"
        Identifier  "Marble Mouse"
        MatchProduct "Logitech USB Trackball"
        Option "EmulateWheel" "true"
        Option "EmulateWheelButton" "8"
        Option "XAxisMapping" "6 7"
        Option "Emulate3Buttons" "true"
EndSection

Using libinput[编辑 | 编辑源代码]

As of version 3.16 GDM/Gnome uses libinput. For the device to work as described in the above section (note that wheel click emulation is not yet supported by libinput) you need to install xf86-input-libinput^包 and instead append this to /etc/X11/xorg.conf.d/10-libinput.conf.

/etc/X11/xorg.conf.d/10-libinput.conf

Section "InputClass"
        Identifier      "Marble Mouse"
        MatchProduct    "Logitech USB Trackball"
        Driver          "libinput"
        Option          "ScrollMethod" "button"
        Option          "ScrollButton" "8"
EndSection

Additional tweaks[编辑 | 编辑源代码]

Console (gpm)[编辑 | 编辑源代码]

See Console mouse support for details. Within the console you can use gpm with type option set to imps2. Edit /etc/conf.d/gpm such that:

GPM_ARGS="-m /dev/input/mice -t imps2"

This lets you use the large left button for selecting text and the right button to extend the selection. The small left button acts as a middle-click; it pastes the selection.

Chromium browser[编辑 | 编辑源代码]

By default, Chromium treats a middle-click as a paste command. This choice stems from "Linux tradition", not the capricious whim of one developer. Like myself, you may prefer a Windows approach. I want the middle button(s) to initiate automatic scrolling, not pasting:

A browser extension AutoScroll allows middle-click to initiate automatic scrolling.
This extension is helpful for any Linux user with a wheel mouse, not just Marble Mouse users.
A middle-click initiates automatic scrolling when clicked on a blank area of a web page.

When you program both small buttons to emit middle-click, either button can initiate automatic scrolling. That is a click function.
When you program one of the small buttons to act as scroll modifier (mouse setup), you can manually scroll web pages without fixing the browser. That is a press‑and‑hold function. (I recommend installing AutoScroll even though it is not absolutely necessary for scrolling.)
After you assign the scroll modifier to one of the small buttons, the small buttons act a bit differently from one another. The difference is seen when you compare their "press‑and‑hold" behaviors.

Be sure to install AutoScroll; the similarly-named Auto Scroll extension implements a different feature.

This information also applies to the browser called Google Chrome.

Firefox browser[编辑 | 编辑源代码]

Older versions of Firefox map horizontal-scrolling hardware to perform browser back and browser forward navigation.

This makes vertical scrolling using the trackball almost impossible.

The slightest horizontal motion triggers a URL redirection. To fix this:

Enter about:config in the location bar
Find the internal variable named mousewheel.horizscroll.withnokey.action. Set its value to 0.
It may be useful to set mousewheel.horizscroll.withnokey.numlines to 1 as well.
