[Intel-gfx] Question about how brightness up/down to call the code of xf86-video-intel like intel_output_dpms_backlight etc

[Li, Hao H]

Hi

When we press the key like brightness up/down from keyboard, kernel will receive the keyevent.
My question is how the keyevent from kernel call the code of xf86-video-intel like intel_output_dpms_backlight etc to adjust the backlight.
Can someone help to explain more details about it?


Thanks!

Li Hao
