And kernel(after 3.2) supports an interface to turn on/off the LED, user space app should take the responsibility to handle this, and I think gnome-settings-daemon is the best one. The interface is in /sys To turn on the LED echo 1 > /sys/class/leds/dell-laptop::touchpad/brightness To turn it off echo 0 > /sys/class/leds/dell-laptop::touchpad/brightness To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/914348/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
