下一篇：There are many ways to control brightness. According to this discussion[1] and this wiki page [2], the control method could be divided into these categories: brightness is controlled by vendor specified hotkey. And there is no interface for OS to adjust brightness. brightness could be controlled by ACPI ACPIIt is often possible to adjust the backlight by ACPI. This controls the actual LEDs or cathodes of the screen. When this ACPI option is available, the illumination is controllable using a GUI slider in the Display/Screen system settings or by simple commands on the CLI. Different cards might manage this differently. Check /sys/class/backlight to find out: # ls /sys/class/backlight/intel_backlight The directory contains the following files and folders: actual_brightness brightness max_brightness subsystem/ uevent # cat /sys/class/backlight/acpi_video0/max_brightness # echo 5 >/sys/class/backlight/acpi_video0/brightness acpi_osi=Linux acpi_backlight=vendor acpi_osi=Linux acpi_backlight=legacy 看了这个之后，很显然，问题就在于acpi_backlight=vendor will prefer vendor specific driver (e.g. thinkpad_acpi, sony_acpi, etc.) instead of the ACPI video.ko driver. 本文来源：博客园作者：浮沉雄鹰
