Download it from

Installation for the desperate:
1) type 'make' to compile this package.
2) type 'make install' to install the module and make it autoboot each time your Linux box starts
3) type 'make uninstall' if you want to uninstall the package
4) type 'make clean' if you want to remove the acpi_lcd.o (module) that the 'make' command created
5) type '1' in your shell in order to lower your brightness to level 1 (keys 1 through 9 should work)
--------------------------------
Detailed Installation Instructions:
1) type 'make' to compile this package.
IMPORTANT: In order for the compiler to work, you must have your kernel sources installed.
Type 'uname -r' to see the version of your kernel.
You NEED to have the /usr/src/KERNEL-VERSION folder in your system for this to work
For instance, if I type 'uname -r' this is what I see:
2.4.22-6mdkcustom
Since I have the '/usr/src/2.4.22-6mdkcustom' folder in my system, I can proceed
2) type 'make install' to install the module and make it autoboot each time your LInux box starts
This will:
- copy the 'acpi_lcd.o' file to your '/lib/modules/KERNEL-VERSION/kernel/drivers/acpi' folder
- create a copy of your '/etc/modules' file (/etc/modules.acpi_lcd) as a backup
- add the following line to your '/etc/modules'file:
acpi_lcd
- create the '/usr/local/acpi_lcd' folder with 10 little scripts that should help you control your brightness
- Create symbolic links from '/usr/local/acpi_lcd/*' to '/usr/local/bin/'. This will help you control your brightness with a touch of a button
I have Mandrake 9 and that file allows me to add modules I want to autostart with my box.
3) type 'make uninstall' if you want to uninstall the package
This will:
- Unload the 'acpi_lcd' module if you're running it
- replace the '/etc/modules' file with the original one (/etc/modules.acpi_lcd)
- remove the '/lib/modules/KERNEL-VERSION/kernel/drivers/acpi/acpi_lcd.o' file from your system
4) type 'make clean' if you want to remove the acpi_lcd.o (module) that the 'make' command created
This command will remove the 'acpi_lcd.o' file from your source directory (This one!)
This is in case you want to have a fresh source in order to install the 'acpi_lcd' module to a new kernel
/lib/modules/KERNEL-VERSION/kernel/drivers/acpi
5) type '1' in your shell in order to lower your brightness to level 1 (keys 1 through 9 should work)
You should now be able to control the brightness of your Toshiba laptop by going to the shell and typing any of the numeric keys. Key# '1' stands for the lowest resulotion (level1) while the key # '9' stands for the highest resolution
You can also control the brightness of your screen by typing 'echo "brightness: xx" > /proc/acpi/lcd"
Where 'xx' is a value between 00 to 99
(Use multiple of ten here)
BETA TESTING:
This Kernel module has been sucessfully installed in a Mandrake 9 (2.4.22-6mdk) Distro.
It should work on most distros though
Any comments?
