问题描述：
昨天升级了ubuntu15.10，升级之后很多15.04让人不爽的东西消失了，大快人心，但是突然发现自己的触摸板不怎么好用了，原来可以点击，双指点击代表右键，三指点击代表鼠标中键的功能不见了，现在点击都不能够点击，真奇怪，最后看了下面这个教程终于高懂了。
参考这个
终端输入
synclient -l
显示
这里就是你的触摸板可以有什么功能，我要恢复到以前的功能
所以只进行了下面的修改
synclient EmulateMidButtonTime=1 //开启中键功能 synclient TapButton1=1 //1代表左键 synclient TapButton2=3 //3在未开启中键时代表回车，开启中键后代表中键 synclient TapButton3=2 //2代表右键
我没有找到配置文件（不会找啊，大家知道的告诉我吧，感激不尽）
我只好将命令写到了/etc/rc.local里面～_~||
哈哈，我明白了，根据他的教程我locate了一下synaptics.conf然后在/usr/share/X11/xorg.conf.d/下面发现了50-synaptics.conf这个文件，名字跟教程里的差不多
打开看一下
# Example xorg.conf.d snippet that assigns the touchpad driver # to all touchpads. See xorg.conf.d(5) for more information on # InputClass. # DO NOT EDIT THIS FILE, your distribution will likely overwrite # it when updating. Copy (and rename) this file into # /etc/X11/xorg.conf.d first. # Additional options may be added in the form of # Option "OptionName" "value" # Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" # This option is recommend on all Linux systems using evdev, but cannot be # enabled by default. See the following link for details: # http://who-t.blogspot.com/2010/11/how-to-ignore-configuration-errors.html MatchDevicePath "/dev/input/event*" EndSection Section "InputClass" Identifier "touchpad ignore duplicates" MatchIsTouchpad "on" MatchOS "Linux" MatchDevicePath "/dev/input/mouse*" Option "Ignore" "on" EndSection # This option enables the bottom right corner to be a right button on clickpads # and the right and middle top areas to be right / middle buttons on clickpads # with a top button area. # This option is only interpreted by clickpads. Section "InputClass" Identifier "Default clickpad buttons" MatchDriver "synaptics" Option "SoftButtonAreas" "50% 0 82% 0 0 0 0 0" Option "SecondarySoftButtonAreas" "58% 0 0 15% 42% 58% 0 15%" EndSection # This option disables software buttons on Apple touchpads. # This option is only interpreted by clickpads. Section "InputClass" Identifier "Disable clickpad buttons on Apple touchpads" MatchProduct "Apple|bcm5974" MatchDriver "synaptics" Option "SoftButtonAreas" "0 0 0 0 0 0 0 0" EndSection
我们看到注释里面有要求
# Example xorg.conf.d snippet that assigns the touchpad driver # to all touchpads. See xorg.conf.d(5) for more information on # InputClass.
//不要编辑这个文件，你的发行版很可能被重写当他被升级的时候，你需要将这个文件复制到/etc/X11/xorg.conf.d # DO NOT EDIT THIS FILE, your distribution will likely overwrite # it when updating. Copy (and rename) this file into # /etc/X11/xorg.conf.d first. # Additional options may be added in the form of # Option "OptionName" "value" #
那我们就复制呗
当然我没有xorg.conf.d文件
新建一个
/etc/X11$ sudo mkdir xorg.conf.d
然后复制
/etc/X11$ sudo cp /usr/share/X11/xorg.conf.d/50-synaptics.conf ./xorg.conf.d/
然后修改为他要求的模样
