<pre>Yes,
root@alanz-laptop:~# echo 649450 >
/sys/class/backlight/intel_backlight/brightness
root@alanz-laptop:~# echo 2649450 >
/sys/class/backlight/intel_backlight/brightness
behaves as expected. The second value comes from
root@alanz-laptop:~# cat
/sys/class/backlight/intel_backlight/max_brightness
2649450
Thanks
