What is xinput
xinput is a tool used to configure and test X input devices, including but not limited to keyboard, mouse, etc. This is used to close the touchpad. Based on the same principle, you can close the keyboard, etc.
xinput is an artifact for configuring and testing X input devices under Linux. It has the following functions (which we will use)
xinput (list ): Type xinput directly or follow the list parameter, and all the input devices of the machine will be listed, including name, ID, level
- ##xinput list –id-only: only list the devices ID (serial number, may change every time you boot up)
- xinput map-to-output: Map the input device to the output, such as mapping the touch screen to a certain screen
- xinput list-props: List the detailed information of a device, followed by the device ID.
xinput list
xinput list-props 12
xinput set-prop 12 'Device Enabled' 0
xinput set-prop 12 154 0
xinput set-prop 12 'Device Enabled' 1 # 或 xinput set-prop 12 154 1
Compile xinput without Makefile under Linux
xinput is a tool in xorg, used to set the input device to match the screen. It is compiled to make it easier to call the functions inside. There is configure in the source code that can generate a Makefile, but because the installation source of the Linux version used is invalid, the dependent packages cannot be completed (yum install is invalid), and the makefile cannot be generated. Now I have found a similar version of the source code, from which I can extract what I need.Directly using gcc to compile the source file *.c
will prompt that some header files cannot be found, such asUnknown type name 'XIDeviceInfo'
The header file selection error caused by the lack of macro definition, can Specify gcc -DHAVE_XI2#VERSION in the compilation command.
is not declared. A macro definition is required, but it cannot be specified on the command line. Add#ifndef VERSION #define VERSION "xinput 1.6.2a" #endif
'XineramaQueryExtension' undefined reference in xinput.h
There are some library files that need to be linked, such as -lXineramaCheck whether there is a correct library file or link in the lib64 path, just end with so
sudo ln -s /lib64/libXinerama.so.1 /lib64/libXinerama.so
Correct installation of the software package should generate a *.pc file
configure detects the pc file and generates a makefile based on the dependencies in the PC fileprefix=/usr
exec_prefix=/usr
libdir=/usr/lib64
includedir=/usr/include
