Pseudo-Brightness-Driver

A linux kernel module to control brightness 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.

To run

• Use make to generate .ko file
• Install using insmod bright.ko files
• Go to cd /dev and create sudo mknod /dev/bright c 242 0 where 242 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 777 bright
• To remove rmmod bright
• To view available kernel mods lsmod

To provide input from keyboard

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 "b" > /dev/bright
$ echo "v" > /dev/bright

• "b" is to increase brightness
• "v" is to decrease brightness

Aslo there is a shell scipt run it as that reads in input from user infinitely: ./b.sh
