Keyboard backlight on VPCS11E7E with Ubuntu 10.10

Italiano | English

Useful especially to save your battery. First off download this program:

http://code.google.com/p/vaio-f11-linux/issues/detail?id=6#c10

extract and compile it

make && sudo make install

This will install kbd_lit in /usr/local/sbin, which has two options:

  • -d Disable backlight
  • -e Enable backlight

this command must be run with root privileges (sudo).

Since it’s inconvenient to open a terminal every time, I associated this program to the magnify function keys (F9 and F10), which on my laptop look like this:

if you want this shortcut too, paste this into a terminal:

sudo -s
cd /etc/acpi
wget -c http://dl.dropbox.com/u/737114/vpcs11e7e/keyboard-backlight.tar.gz
tar -xzvf keyboard-backlight.tar.gz
rm keyboard-backlight.tar.gz
service acpid restart

This way Fn+F9 will shut the light off and Fn+F10 will turn it on again.
