Public bug reported:
Binary package hint: hal
Brightness notification always shows the same value for laptops with
hardwired brightness control, ex T42.
Problem is get_backlight () function in: hald/linux/addons/addon-
generic-backlight.c
Line 67 reads: g_snprintf (sysfs_path, sizeof (sysfs_path),
"%s/brightness", path);
should be: g_snprintf (sysfs_path, sizeof (sysfs_path),
"%s/actual_brightness", path);
'actual_brightness' holds the current value of brightness.
'brightness' is used to set the brightness, and when read gives the last writen
value!
** Affects: hal (Ubuntu)
Importance: Undecided
Status: New

Generic get_brightness function should read 'actual_brightness' not 'brightness'
