1. s1bl:

s1bl (S1 Brightness Level) is a program to get and set the LCD brightness level of a Toshiba Tecra S1.


2. Installation:

It is just a simple:

gcc -o s1bl s1bl.c

3. Usage:

As s1bl has to write to the extended BIOS the program has to be run with root privileges.

To read out the LCD brightness level use

# ./s1bl -g
brightness level: 4

To set the LCD brightness level use "s1bl -s level" where "level" can be a value between 0 and 7.
The darkest level is 0, 7 is the brightest.

# ./s1bl -s 6
brightness level: 6

4. License

s1bl is released under the GPL.
