A linux kernel module to control mouse pointer using keyboard. This is an experiment to fiddle with drivers. It may not have any real life use case but was fun to create. It still has some bugs and needs a lot of improvements.

• Use make to generate .ko file
• Install using insmod mousek.ko files
• Go to cd /dev and create sudo mknod /dev/mousek c 247 0 where 247 will be replaced by major number given while installing this module. This major number can be viewed in logs using dmesg
• Provide permission to this char file sudo chmod 666 mousek
• To remove rmmod mousek
• To view available kernel mods lsmod

Use the available commands: All of the commands are being fed into dev mousek char file. This can be done by echo in /dev directory. For example -

$ echo "i dllwW" > mousek
$ echo "ll" > mousek
$ echo "x 434" > mousek

First character will tell what command to follow i : instruction sequence followed by commands example

• echo "i udrrl" > mousek or echo "i ddrqQ" > mousek where -

  • "i" is command
  • "l" for -10 pixel X axis
  • "r" for 10 pixel X axis
  • "d" for 10 pixel Y axis
  • "u" for -10 pixel Y axis
  • "q" for left click down
  • "Q" for left click Up
  • "w" for right click down
  • "W" for right click Up

• x : relative value in X Axis

  • Example: echo "x 250" > mousek

• y : relative value in Y Axis

  • Example: echo "y 200" > mousek

• l : left click , ll : double left click

  • Example: echo "l" > mousek or echo "ll" > mousek

• r : right click

  • Example: echo "r" > mousek

• Input sequence command doesn't respect order of commands at the moment.
• Unable to move visible mouse pointer symbol on screen (for this, need to mess with x10 demon I guess).

This kernel module comes with a GPL license.
