What do you want to do? Turning off the display completely or just turn off the backlight? ACPI can only decrease the screen backlight to the minimum value that BIOS tells it. Sometimes this equals turning off the backlight while sometimes this just means dimming the screen. But this doesn't equal turning off the display. To turn off/on the display, you need to ask help for some graphics tools, say "xrandr --output LVDS --off"/"xrandr --output LVDS --auto". Anyway, this is not an ACPI problem, bug closed. |
