So far it looks like acpi_video attaches, but the lcd0 device is not active. More interestingly, if you press brightness shortcuts, acpi_video can see the brightness value change while screen does not actually change. My conclusion based on bullshit and poking around in the acpidump, is that possibly either: 1) We need to call some ACPI handle to put ACPI in charge of brightness (google acpi brightness trapdoor) 2) acpi_video is attaching to the nvidia optimus hooks (yes, they're there, I know we don't have that option) and is missing the IGD video (VIGD/PEG etc) 3) Something else is wrong with either acpi, acpi_video, or bios that is preventing ACPI from working? I am going to take more of a look tonight. I think I can just hack in some ACPI calls straight to the ec if that will work, which might also include the correct ones to resume the display without KMS? Calling some _ON function or something perhaps Thanks! Matt
