问题描述
我知道我可以检查触摸板是否处于活动状态
gconftool-2 --get /desktop/gnome/peripherals/touchpad/touchpad_enabled
我可以将其设置为禁用/启用
gconftool-2 --set --type boolean /desktop/gnome/peripherals/touchpad/touchpad_enabled true
使用 lsusb，我可以看到所有连接的 USB-devices。这是我的鼠标：

如何在连接 USB-mouse 时使用它自动停用我的触摸板，并在 USB-mouse 消失后再次激活它？
最佳回答
This project 似乎不再维护。
对于 natty，有一个触摸板指示器应用程序。它可以设置为在插入或拔出鼠标时禁用/启用触摸板。我不知道它是否也适用于较旧的 Ubuntu 版本。
https://launchpad.net/touchpad-indicator
sudo add-apt-repository ppa:atareao/atareao
sudo apt-get update
sudo apt-get install touchpad-indicator
次佳回答
您可以设置 udev 规则来禁用/启用触摸板。 ArchLinux wiki 有以下规则用于从 udev 切换 Synaptic 触摸板：
ACTION=="add", SUBSYSTEM=="input", KERNEL=="mouse[1-9]", ENV{DISPLAY}=":0.0",
ENV{XAUTHORITY}="/home/USERNAME/.Xauthority", ENV{ID_CLASS}="mouse", RUN+="/usr/bin/synclient TouchpadOff=1"
ACTION=="remove", SUBSYSTEM=="input", KERNEL=="mouse[1-9]", ENV{DISPLAY}=":0.0",
ENV{XAUTHORITY}="/home/USERNAME/.Xauthority", ENV{ID_CLASS}="mouse", RUN+="/usr/bin/synclient TouchpadOff=0"
第三种回答
我不确定是否所有笔记本电脑都使用 Synaptiks，但您可以尝试使用它。如果您尚未安装，请在终端中写入： $sudo apt-get install kde-config-touchpad ，然后是 $synaptiks ，最后在菜单 \xabTouchpad management\xbb 中检查：
-
登录时自动启动
-
如果插入鼠标，则自动关闭触摸板
我希望这些信息对您很有价值！
第四种回答
您可以创建一个脚本，并在您想要禁用/启用触摸板时执行它。
/usr/local/bin/touchpad_toggle.sh
#!/bin/bash
declare -i ID
ID=`xinput list | grep -Eio 'touchpad\s*id\=[0-9]{1,2}' | grep -Eo '[0-9]{1,2}'`
declare -i STATE
STATE=`xinput list-props $ID|grep 'Device Enabled'|awk '{print $4}'`
if [ $STATE -eq 1 ]
then
xinput disable $ID
# echo "Touchpad disabled."
# notify-send 'Touchpad' 'Disabled' -i /usr/share/icons/Adwaita/48x48/devices/input-touchpad.png
else
xinput enable $ID
# echo "Touchpad enabled."
# notify-send 'Touchpad' 'Enabled' -i /usr/share/icons/Adwaita/48x48/devices/input-touchpad.png
