Instructions for installing acpi_call:

 

sudo apt-get install git build-essential

git clone https://github.com/mkottman/acpi_call.git

cd acpi_call

make

sudo make install

sudo depmod

sudo modprobe acpi_call

sudo vim /etc/modules

acpi_call

 

You may then remove the acpi_call directory.

Note that you may have to recompile acpi_call when you update your kernel,

but probably not for minor updates.

 

Make acpi_call usable without sudo:

 

sudo chmod 666 /proc/acpi/call

sudo vim /etc/rc.local

chmod 666 /proc/acpi/call

 

 

You may then try changing the keyboard backlight value with:

 

You can now adjust the brightness with this command:

echo "\_SB.KBLT.KBCM 0" > /proc/acpi/call

or: /opt/kbd-backlight.sh 0

Use 100 to turn it fully on again. Use a value in between to adjust the brightness.

 

I recommend that you set your keyboard shortcuts in CCSM instead of the normal

keyboard shortcut manager, because many shortcuts set there will just stop

working after reboot. Be *very* careful with this tool!!!

 

sudo apt-get install compizconfig-settings-manager

ccsm

 

Enable the 'Commands' plugin and set these commands:

/opt/kbd-backlight.sh up

/opt/kbd-backlight.sh down

/opt/kbd-backlight.sh 100

/opt/kbd-backlight.sh 0

 

And then the key bindings:

<Alt>F7

<Alt>F6

<Shift><Alt>F7

<Shift><Alt>F6

 

 

Uninstall with:

sudo rm /opt/kbd-{backlight,lock}.sh /etc/pm/sleep.d/70-kbd-backlight

rm ~/.config/autostart/kbd-{backlight,lock}.sh.desktop

You may also want to remove your keyboard shortcuts in CCSM.

 

I recommend Chromebook users to also look at my other gist for mapping the

function keys with Xmodmap: https://gist.github.com/stefansundin/6987698
