------- Comment #9 from [EMAIL PROTECTED]  2008-03-07 10:06 -------
I am able to change brightness via sys I/F. Valid values for brightness are
0,25,50,75 or 100. Any other value sets monitor brightness to maximum (and
actual_brightness to 100). dmesg output after I changed brightness from 0 to 25
(echo 25 > /sys/class/backlight/acpi_video0/brightness):
