Hi, I'm confused. There is a commit 8c16f3303c34 in linux-stable. Its idea is to reduce calls to low level backlight drivers. But what happens now, at least in my case, is that on first blank event after boot bd->fb_bl_on[node] is false, backlight_update_status is not called and backlight is left on. As I understand it all FBs must change their state at least once before backlight driver is completely synced with framebuffers. I don't understand how is this supposed to work. I could initialize fb_bl_on and use_count for the initial state where FBs are unblanked but then backlight driver had to know how many backlights there are. I have not found any hints how other drivers might solve this. Could anybody enlighten me in my confusion? -- Timo -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
