ESE Key Daemon is a multimedia keyboard driver for Linux.



This program was inspired by discussion about Funkey and

2.6 Linux kernels. Just read what Vojtech Pavlik think

about Funkey patch. (at the end of file)



How to use this program?



1. Compile kernel with event interface input support.

(generic kernels should have it)



2. If compiled as a module (best choice) load module.

(type "modprobe evdev" as root)



3. If you know what permissions are set it correctly ;-P

(e.g. prevent users from installing key loggers)



4. Compile program.

(type "./bootstrap ; ./configure ; make")



5. Install program.

(type "make install" as root)



6. Run keytest and test if your keys works.

(type "keytest")



7. Run learnkeys and make config file.

(type "learnkeys config_file_name")



8. Edit config file generated by learnkeys.

(use your favorite editor)



9. Run it with the config file name.

(type "esekeyd config_file_name",

you don`t have to run it as root if you set permissions correctly,

if you want to do root need things (like init 5) use sudo,

my config file is included in examples directory)



10. Have fun!

You shouldn't need any patch for 2.6 to implement this functionality.

Basically you need to modify the funkey daemon to do this:



1) Open /proc/bus/input/devices and read it to find out which device

is the system keyboard.

2) Open the correct /dev/input/event? device

3) Program the scancode/keycode mappings using the EVIOCSKEYCODE

ioctl()

4) Use the EVIOCGRAB ioctl() to prevent any other program to get

keycodes from the keyboard.

5) Open /dev/uinput and create a new virtual keyboard

6) Read events from /dev/input/event? and process them. Either forward

them to /dev/uinput (normal keys) or do whatever action is needed

(fun keys)



Does that sound reasonable?



Another option is to omit steps 4 and 5, and just let the extra keys

reach the applications. If they're not mapped in kernel/xfree keymaps,

they'll be simply ignored.



One more thing: Microsoft standardized some of the WWW/Multimedia keys.

I'll be changing the default scancode/keycode/rawmode tables to support

them soon.
