FnFX enables owners of Toshiba laptops to change the LCD brightness,
control, the internal fan and use the special keys on their keyboard
(Fn-x combinations, hot-keys).
The internal functions will give the possibility to map the Fn-Keys to
functions like volume up/down, mute, suspend to disk, suspend to ram
and switch LCD/CRT/TV-out. These functions heavily depend on the
system and/or kernel configuration. You will need at least a kernel
(v2.4.x, v2.5.x, v2.6.x) with ACPI and Toshiba support (CONFIG_ACPI
and CONFIG_ACPI_TOSHIBA).
