comment Can't change brightness on Toshiba l755 laptop
In /sys/class/backlight/toshiba I have many files: "brightness" "max_brightness" "actual_brightness" which I can modify. But those files' values doesn't seem to really affect the actual screen brightness.

The thing is, I actually can change the value of it using function keys or from parameters, it's the screen that doesn't change the brightness. Moreover, I don't have the "acpi_bideo0" folder in backlight, just the "toshiba".
