禁用触摸板中间按钮的复选框在哪里？

这是 Debian 9。我以前没有过这个功能，也许是因为我一直使用带有单独按钮的触摸板。现在，在无按钮触摸板上有中间按钮功能，它可以不断关闭我的浏览器选项卡，以及它所发挥的其他奇怪的有用技巧。我已经搜索了关闭此功能的选项，但在“所有设置”或通过调整工具都找不到它。网上对此很沉默，或者我不知道如何询问。复选框/开关是否存在？那它在哪里呢？或者CLI方法是什么？

安装就足以xserver-xorg-input-synaptics停止中间按钮功能。需要重新启动。 （也许还有另一种更温和的方法来应用更改。）安装禁用了 Gnome 中“所有设置”中可用的一些选项，例如边缘滚动。这些是安装后的选项：

$ synclient -l
Parameter settings:
LeftEdge                = 1668
RightEdge               = 5354

SingleTapTimeout        = 180
ClickTime               = 100
EmulateMidButtonTime    = 0
EmulateTwoFingerMinZ    = 282
EmulateTwoFingerMinW    = 7
VertScrollDelta         = 109
HorizScrollDelta        = 109
VertEdgeScroll          = 0
HorizEdgeScroll         = 0
CornerCoasting          = 0

LockedDragTimeout       = 5000
RTCornerButton          = 0
RBCornerButton          = 0
LTCornerButton          = 0
LBCornerButton          = 0
TapButton1              = 0
TapButton2              = 0
TapButton3              = 0
ClickFinger1            = 1
ClickFinger2            = 3
ClickFinger3            = 2
CircularScrolling       = 0
CircScrollDelta         = 0.1
CircScrollTrigger       = 0
CircularPad             = 0
PalmDetect              = 0
PalmMinWidth            = 10
PalmMinZ                = 200
CoastingSpeed           = 20
CoastingFriction        = 50
PressureMotionMinZ      = 30
PressureMotionMaxZ      = 160
PressureMotionMinFactor = 1
PressureMotionMaxFactor = 1
GrabEventDevice         = 0
TapAndDragGesture       = 1
AreaLeftEdge            = 0
AreaRightEdge           = 0
AreaTopEdge             = 0
AreaBottomEdge          = 0
HorizHysteresis         = 27
VertHysteresis          = 27
ClickPad                = 1
RightButtonAreaLeft     = 3511
RightButtonAreaRight    = 0
RightButtonAreaTop      = 4066
RightButtonAreaBottom   = 0
MiddleButtonAreaLeft    = 0
MiddleButtonAreaRight   = 0
MiddleButtonAreaTop     = 0
MiddleButtonAreaBottom  = 0

这些设置似乎驻留在/usr/share/X11/xorg.conf.d/70-synaptics.conf.

配置调整可以写入/etc/X11/xorg.conf目录或目录中/etc/X11/xorg.conf.d/。 （显然需要重新启动。也许还有另一种方法......）
