official ivad homepage
This page provides information about the improvedvaio daemon created as a substitute for these various command line tools with the same functionality.
ok. what is it?
the ivad listens for sony vaio specific events like the jog dial, Fn-XX keys or the blue tooth button by using the sonypi linux kernel driver. after receiving these events it can do whatever you want, e.g. changing brightness, volume or executing a program.
Unfortunately ivad is permanently wasting about 2% of the cpu power. I'm gonna fix it later.
alpha versions can be found here
