关闭时禁用 x1 carbon 上的触摸屏

我喜欢将 x1 carbon 的盖子合上，然后将其插入外部显示器。问题是，触摸屏出现故障，导致 USB 鼠标出现奇怪的跟踪问题（光标跳动）。

我编辑了 /usr/share/X11/xorg.conf.d/10-evdev.conf 如下：

Section "InputClass"
        Identifier "evdev touchscreen catchall"
        MatchIsTouchscreen "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
        Option "Ignore" "on"
EndSection

这解决了我使用外接显示器时的问题，但当我后来在没有外接显示器的情况下使用笔记本电脑时，触控板无法工作。

有人知道如何禁用触摸屏但保持触控板功能正常吗？

这是文件的全部内容（不包括选项"Ignore"）。

# Catch-all evdev loader for udev-based systems
# We don't simply match on any device since that also adds accelerometers
# and other devices that we don't really want to use. The list below
# matches everything but joysticks.

Section "InputClass"
        Identifier "evdev pointer catchall"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev keyboard catchall"
        MatchIsKeyboard "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev tablet catchall"
        MatchIsTablet "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev touchscreen catchall"
        MatchIsTouchscreen "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection
