Here are the requested informations. As you will see there are two folders in /sys/class/backlight
When I use the keyboards shortcuts to modify the brightness, the file /sys/class/backlight/acpi_video0/brightness is modified but it has no effect on the actual brightness. When I manually write the brightness into the file /sys/class/backlight/intel_backlight/brightness, the actual brightness is modified. Some software (like cairo dock manage to change the brightness). I guess they use the right folder.
